Saya mengalami masalah yang sangat membuat frustrasi: Rake menjadi bodoh.
Begini caranya masalah muncul:
$ rails new test_app
$ rails generate scaffold new_scaffold field1:string field2:text
Keduanya bekerja dengan baik, tetapi ketika saya melakukan ini,
$ rake db:migrate
Saya mendapatkan kesalahan berikut.
(in /home/mikhail/test_app)
rake aborted!

Saya sudah mencari di Internet untuk kesalahan yang sama / sama, dan orang-orang sudah memilikinya. Sepertinya tidak ada yang bisa menyelesaikan masalah!
Bagaimana saya memperbaiki masalah ini?
bundle update rake
dulu. Lalu aku memeriksanyabundle show rake
. Seharusnya mengatakan 0.8.7. Lalurake db:migrate
.
