Ruby On Rails，錯誤運行命令“ rails generate controller”，輸入/輸出錯誤@ rb_sysopen，（Errno :: EIO）

Question

開始時，當我運行rails generate controller welcome homepage到我的項目目錄中時，該命令運行正常，並生成app/controllers/welcome_controller.rb並發送路線get welcome/homepage

User1@My-Machine:~/MyProject$ rails generate controller welcome homepage
/home/User1/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-4.2.6/lib/rails/app_rails_loader.rb:39: warning: Insecure world writable dir /home/User1/.rbenv/versions in PATH, mode 040777
      create  app/controllers/welcome_controller.rb
       route  get 'welcome/homepage'

之后，該命令立即遇到以下錯誤：

/home/User1/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/thor-0.19.1/lib/thor/actions/inject_into_file.rb:98:in `binread': Input/output error @ rb_sysopen - /home/User1/MyProject/config/routes.rb (Errno::EIO)

然后是文件列表。

有人知道如何解決嗎？

Answer 1

這個答案有點不合時宜，但是我對當前版本的WSL的經驗是rbenv在WSL中運行時有問題，而RVM似乎可以正常工作。 最初的問題聽起來像是您可能正在從Windows界面移動linux特定文件，例如/ home / user / file（來自appdata區域）-絕對不要這樣做。 僅從bash操作這些文件，因為會發生損壞和奇怪的情況 。

不確定為什么無法在您的設置中創建或正確顯示事物，但是總的來說，這對我有用：

使用RVM，並在這個家伙的幫助下，我得出結論，我需要

bundle config --delete bin
rake rails:update:bin
git add bin

和使用

bash --login

從Windows登錄到bash的交互式版本。

我已經成功地從Bash和Windows的掛載空間（即/mnt/c/Users/Tim/Desktop/railsapp創建和使用項目

我從bash運行生成器而不是其他東西，但是在Windows中從Sublime編輯文件的內容。

祝好運！
