tôi đã làm một số tìm kiếm và thử như sau

1. tôi đã cố gắng để thêm sau đây trong boot.rb, sau đó config/deploy.rb tập tin, Nó đã không làm việc.

require 'yaml' 
YAML::ENGINE.yamler = 'syck' 

2. tôi đã cố gắng loại bỏ manifest.yml và tập tin asset_manifest.yml, sau đó cố gắng để triển khai một lần nữa. Nó không hoạt động

3. Tôi đã kiểm tra tệp .bashrc và không có lỗi cú pháp.

Vui lòng giúp đỡ nếu bạn tìm thấy những gì tôi thiếu ở đây.

Answer 1

Đã xảy ra lỗi trong tệp ~/.bashrc của tôi, đang tải phiên bản Ruby cũ.

Có en lỗi khi tôi xem rvm list

default [usr/bin missing ruby] 
ruby-2.1.2 

tôi loại bỏ 'default' thư mục của tôi từ ~/.rvm/rubies/ sau đó giao 'ruby-2.1.2' như ruby ​​mặc định sử dụng rvm use ruby-2.1.2 --default và vấn đề đã được giải quyết.
