Untuk beberapa alasan setelah menginstal Express secara global di mesin saya dengan npm install -g express
jika saya cd
masuk ke direktori dan mencoba menjalankan ekspres saya mendapatkan kesalahan berikut:
express: command not found.
Bahkan jika saya menjalankannya dengan sudo
saya masih mendapatkan hasil yang sama. Saya telah mencoba beberapa solusi berbeda untuk masalah ini dan tidak ada yang berhasil. Saya telah menginstal node di homebrew
mana beberapa utas di Stack Overflow yang diindikasikan mungkin menjadi masalah jadi saya benar-benar menghapus node dan menginstal ulang melalui penginstal di nodejs.org (Saya sekarang menjalankan v0.10.26) dan masalah masih berlanjut.
Jika saya masuk ke /usr/local/lib/node_modules
Express saya ada di sana tetapi di dalam / usr / local / bin tidak ada apa-apa tentang Express. Saya tidak yakin apakah itu masalah atau tidak tetapi mengingat ada binari untuk paket node yang diinstal secara global lainnya di direktori itu, saya pikir mungkin ada yang salah di sana.
Ini adalah keluaran tepat yang saya dapatkan ketika saya menginstal:
