Có thể xảy ra vấn đề đá quý sprockets-ray?

Question

Tôi vừa tạo một hộp Vagrant mới để có thể phát triển ứng dụng Rails của mình. Hộp là thương hiệu mới và có Ruby, MySQL, vv được cài đặt để có thể phát triển.

Tôi đã cài đặt tất cả các đá quý vv nhưng khi tôi cố gắng để bắt đầu ứng dụng tôi nhận được như sau:

Tôi đã nhìn nhưng dường như không thể tìm ra những gì đang gây ra nó.

Bất kỳ ai cũng có thể chỉ cho tôi đúng hướng?

Answer 1

Trường hợp ngoại lệ được ném vào this line, vì vậy tôi đoán bạn có sau đâu đó trong các tập tin cấu hình của bạn:

config.assets.precompile = false 

thiết lập cấu hình này nên xác định một loạt các tài sản mà bạn muốn được biên dịch sẵn, nó không được đặt thành false. Xem Rails guides để biết thêm thông tin.

Để kiểm tra giả thuyết này, tôi cấu hình 5 dự án Rails thử nghiệm với dòng trên và có những ngoại lệ như nhau:

.../gems/sprockets-rails-3.2.0/lib/sprockets/railtie.rb:108:in `block in <class:Railtie>': undefined method `+' for false:FalseClass (NoMethodError)
