Gagal menginstal paket Python Cryptography dengan PIP dan setup.py

Ketika saya mencoba menginstal paket Kriptografi untuk Python melalui pip install cryptographyatau dengan mengunduh paket dari situs mereka dan menjalankannya python setup.py, saya mendapatkan kesalahan berikut:

Saya menemukan posting kesalahan egg_info lainnya (di sini dan di sini ) tetapi solusi yang disediakan tidak akan menyelesaikan masalah saya. Saya juga dapat menginstal paket lain melalui PIP.

PIP versi 1.5.4 setuptools versi 2.2

Saya memiliki masalah yang sama, dan menemukan saya hanya kehilangan ketergantungan (libssl-dev, untuk saya). Sebagaimana dirujuk dalam https://cryptography.io/en/latest/installation/ , pastikan semua dependensi terpenuhi:

Di Windows

Jika Anda menggunakan Windows, Anda harus memastikan bahwa Anda telah menginstal OpenSSL. Ada binari yang telah dikompilasi sebelumnya. Jika instalasi Anda di lokasi yang tidak biasa atur variabel lingkungan LIB dan TERMASUK untuk memasukkan lokasi yang sesuai. Sebagai contoh:

C:\> \path\to\vcvarsall.bat x86_amd64
C:\> set LIB=C:\OpenSSL-1.0.1f-64bit\lib;%LIB%
C:\> set INCLUDE=C:\OpenSSL-1.0.1f-64bit\include;%INCLUDE%
C:\> pip install cryptography

Membangun kriptografi di Linux

kriptografi harus dibangun dengan sangat mudah di Linux asalkan Anda memiliki kompiler C, tajuk untuk Python (jika Anda tidak menggunakan pypy), dan tajuk untuk pustaka OpenSSL dan libffi yang tersedia di sistem Anda.

Untuk Debian dan Ubuntu , perintah berikut akan memastikan bahwa dependensi yang diperlukan diinstal:

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

Untuk Fedora dan derivatif RHEL , perintah berikut akan memastikan bahwa dependensi yang diperlukan diinstal:

sudo yum install gcc libffi-devel python-devel OpenSSL-devel

Anda sekarang seharusnya dapat membangun dan menginstal kriptografi dengan yang biasa.

pip install cryptography

Ini adalah versi ringkas informasi yang ditemukan pada halaman dokumentasi instalasi kriptografi . Lihat halaman itu untuk perincian terbaru.

Karena pertanyaan SO ini terus muncul, saya akan memberikan respons di sini juga (saya adalah salah satu pengembang pyca / kriptografi). Inilah yang Anda perlukan untuk menginstal pyca / cryptography dengan andal di 3 platform utama.

Harap dicatat dalam semua kasus ini, sangat disarankan agar Anda menginstal ke virtualenv dan tidak ke dalam ruang paket global. Ini bukan khusus untuk kriptografi, tetapi lebih merupakan saran umum untuk menjaga agar instalasi Python Anda dapat diandalkan. Ruang paket global dalam OS yang disediakan Python dimiliki oleh sistem dan menginstal hal-hal melalui pip ke dalamnya meminta masalah.

Windows

Tingkatkan ke pip terbaru (8.1.2 pada Juni 2016) dan adil pip install cryptography

kriptografi dan cffi keduanya dikirim sebagai roda yang terhubung secara statis.

OS X

Tingkatkan ke pip terbaru (8.1.2 pada Juni 2016) dan adil pip install cryptography

kriptografi dan cffi keduanya dikirim sebagai roda yang terhubung secara statis. Ini akan berfungsi untuk pyenv Python, sistem Python, homebrew Python, dll. Selama Anda menggunakan pip terbaru, Anda bahkan tidak memerlukan kompiler.

Linux

Pada versi 2.0, kriptografi mengirimkan roda manylinux1. Ini berarti pengguna dengan pip 8.1+ berjalan pada distribusi berbasis glibc (hampir semuanya kecuali Alpine Linux) dan pada x86 / x86-64 (maaf orang Raspberry Pi) tidak lagi memerlukan kompiler atau header karena Anda akan mendapatkan roda yang dikompilasi secara otomatis . Jadi, hal pertama yang harus Anda coba adalah meningkatkan pip Anda!

Jika Anda tidak kompatibel dengan banyaklinux1 maka inilah yang perlu Anda lakukan:

Anda memerlukan kompiler C, libffi + header pengembangannya, dan openssl + header pengembangannya.

Distribusi turunan Debian atau Ubuntu

apt-get install build-essential libssl-dev libffi-dev python-dev diikuti oleh

pip install cryptography

Distribusi Red Hat

yum install gcc openssl-devel libffi-devel python-devel diikuti oleh

pip install cryptography

Bagi Anda yang menjalankan OS X, inilah yang bekerja untuk saya:

brew install openssl
env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib" CFLAGS="-I/usr/local/opt/openssl/include"
pip install cryptography

(Menjalankan 10.9 Mavericks)

Anda mungkin juga ingin mencoba menggabungkan flag dan perintah pip ke yang berikut sesuai komentar di bawah ini:

brew install openssl
env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib" CFLAGS="-I/usr/local/opt/openssl/include" pip install cryptography

Ini bekerja untuk saya di El Capitan

brew install pkg-config libffi openssl
env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography

Anda juga dapat memeriksa utas di sini: https://github.com/pyca/cryptography/issues/2350

Ini memecahkan masalah bagi saya (Ubuntu 16.04):

sudo apt-get install build-essential libssl-dev libffi-dev python-dev python3-dev

dan kemudian berfungsi seperti ini:

pip install cryptography
pip install pyopenssl ndg-httpsclient pyasn1

Rupanya pada versi OSX terbaru ini mungkin disebabkan oleh Apple mengirimkan versi OpenSSL mereka sendiri, yang tidak berfungsi dengan pustaka kriptografi.

Versi terbaru dari pustaka kriptografi dikirimkan dengan dependensi asli mereka sendiri, tetapi untuk mendapatkannya, Anda harus memutakhirkan pip, dan mungkin juga env virtual. Jadi bagi saya, solusinya adalah:

pip install --upgrade --force-reinstall pip virtualenv

Bagaimana saya memecahkan "Dir build gagal gagal untuk kriptografi"
(Saya datang ke sini dari google untuk mencari kesalahan ini.)

catatan : menggunakan virtualenv

TL; DR:

file saya /etc/apt/sources.listtidak dikonfigurasi dengan benar untuk debian 8 saya.

Penjelasan:

Saya ingin menginstal paramiko. paramiko membutuhkan kriptografi.

Saya mendapat kesalahan ini: pertama dengan pip install cryptography:

(...)

dan kemudian dengan sudo apt-get install build-essential:

(Tidak persis kesalahan yang sama dengan OP tapi saya di sini untuk membantu akhirnya )

Memecahkan:

Setelah menguji hampir setiap perintah dari setiap posting saya akhirnya pergi di
https://wiki.debian.org/SourcesList
dan menyalin disisipkan konfigurasi yang memadai saya di file/etc/apt/sources.list

kemudian:

sudo aptitude update

lalu

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

lalu

pip install cryptography

hth

Saya mencoba banyak solusi di atas, tetapi hanya setelah instalasi lib berikut saya dapat menginstal cryptography:

sudo apt install libssl1.0

Saya menggunakan Ubuntu 18.04, tetapi akan bekerja pada Ubuntu 18.10 juga.

Ini bekerja untuk saya (saya menggunakan Ubuntu 14.04):

instal dulu libffi-dev libssl-dev libpython2.7-dev:

sudo apt-get install libffi-dev libssl-dev libpython2.7-dev

kemudian di dalam virtualenv:

pip install cryptography
pip install pyopenssl ndg-httpsclient pyasn1

Jawaban Nick Woodham tidak bekerja pada OSX 10.11 untuk saya, tetapi ini berhasil.

brew install openssl
CFLAGS="-I/usr/local/opt/openssl/include" pip install cryptography==0.8

Jika Anda menggunakan python3, Anda harus menginstal python3-dev. Ini memperbaiki masalah saya sudo apt-get install python3-dev.

Saya mengalami masalah dengan pemasangan cryptography==1.7.1di Ubuntu 16.04 dan tidak ada jawaban di atas yang membantu. Jadi, saya memutakhirkan persyaratan ke 1.8.2 yang kompatibel dan pengaturannya berhasil. Perhatikan bahwa Anda masih perlu membangun esensi & dependensi lain yang disebutkan dalam jawaban teratas (paling banyak dipilih) .

Saya mengalami masalah saat menjalankan sudo pip install cryptographykarena tidak menemukan ffi ketika mencoba mengompilasi. (OSX - Yosemite)

Saya menyelesaikannya dengan mengunduh libffi dan mengatur env var.

$ brew install pkg-config libffi
$ export PKG_CONFIG_PATH=/usr/local/Cellar/libffi/3.0.13/lib/pkgconfig/
$ pip install cryptography

Ini berfungsi pada El Capitan dengan MacPorts:

$ sudo port install openssl
$ env LDFLAGS="-L/opt/local/lib" CFLAGS="-I/opt/local/include" pip install cryptography

Jika Anda sedang membangun sebuah distribusi paket python di .gitlab-ci.yml file dalam untuk GitLab CI yang menggunakan pelari gitlab dikerahkan di mesin AWS EC2

 - apk add --update alpine-sdk && \
 - apk add libffi-dev openssl-dev && \
 - apk --no-cache --update add build-base

Saya perhatikan poster asli jelas menggunakan instalasi windows ... dan jawaban terbaik di atas semua untuk OS lain ... jadi begini. Ini mengasumsikan Anda telah menginstal Python 2.7 yang merupakan versi yang paling banyak didukung (meskipun lama).

1. Instal " Visual C ++ Compiler untuk Python "
2. Buka jendela prompt perintah Administratif

3. Jalankan kembali instalasi pip (paket) mis

   cd C:\Python27\Scripts
   pip install cryptography  (or pycrypto, fabric, etc)

Saya mengalami masalah serupa baru-baru ini. Dalam kasus saya, versi cffidan yang cryptographyditulis di requirement.txt tidak kompatibel (cffi == 1.8.9 dan kriptografi == 1.9). Saya memecahkan pembaruan cffidengan versi terakhir yang tersedia.

Saya benar-benar berlari ke prob yang sama ini mencoba menginstal Scrapy yang tergantung pada kriptografi yang diinstal terlebih dahulu. Saya menggunakan Win764-bit dengan Python 2.7 64-bit diinstal. Jawaban @ jsonm akhirnya bekerja untuk saya, tetapi pertama-tama saya harus menyalin C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvarsx86_amd64.batke x86_amd64subdir dalam direktori bin jadivcvarsall.bat akan berhenti melempar kesalahan mengatakan itu hilang konfigurasi. Jika Anda perlu mengkonfigurasi env vars untuk pengaturan yang berbeda, pastikan untuk menyalin ke file vcvars bat yang sesuai ke subdir yang sesuai atau perintah pertama di bawah ini mungkin tidak berfungsi.

Kemudian saya menjalankan berikut ini dari commandline sesuai instruksi @ jsonm (tweak untuk konfigurasi saya) ...

C:\> "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86_amd64 
C:\> set LIB=C:\OpenSSL-Win64\lib;%LIB% 
C:\> set INCLUDE=C:\OpenSSL-Win64\include;%INCLUDE% 
C:\> pip install cryptography

Dan itu berhasil.

Saya memiliki kesalahan ini juga. Setelah terus mendapatkan kesalahan ini bahkan setelah menginstal openSSL, saya akhirnya mencoba menginstal dari file beroda dari https://pypi.python.org/pypi/cryptography/0.2.2##downloads . Berhasil!

saya mengunduh paramiko kode sumber lengkap dari pypi dan melakukannya

instal setup.py python

itu bekerja dengan sempurna

semua paket pythondev / openssl / libffi default sudah ada di rhel.

mengunduh rpms memiliki ketidakcocokan rpm dan lebih banyak masalah

Saya mengalami masalah yang sama:

pip install cryptography

.
.
.
Installing collected packages: cffi, cryptography
     Running setup.py install for cffi ... error

Kemudian saya menginstal libffi-devel dan masalah terpecahkan

yum install libffi-devel

Kedua perintah itu memperbaikinya untuk saya:

brew install openssl
brew link openssl --force

Saya menyelesaikan ini dengan memutakhirkan dari kriptografi 1.9 ke 2.4.2
