新的Rails應用程序捆綁程序/安裝程序（LoadError）

Question

嘗試創建新的Rails項目時出現此錯誤：

我將cd bundle install到我的項目中並運行bundle install ，但出現此錯誤：

Errno::EACCES: Permission denied @ rb_sysopen - /Users/jameslett/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/nokogiri-1.6.7.1/.autotest
An error occurred while installing nokogiri (1.6.7.1), and Bundler cannot continue. Make sure that gem install nokogiri -v 1.6.7.1 succeeds before bundling.

如果我運行gem install nokogirl再次出現“ Errno :: EACCES”錯誤。

我不確定該怎么解決。 我閱讀了Bundler和Nokogirl文檔，但沒有幫助。

以防萬一，我正在跑步：

ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]

我的寶石ENV是：

我的gem路徑是否引起此錯誤？

Answer 1

你可以試試這個

sudo gem update --system

Answer 2

確保您擁有.rbenv文件夾中的.rbenv文件。

$ sudo chown -R $(whoami) /Users/jameslett/.rbenv

此外，所有文件都應可讀可寫。

$ chmod -R u+rw /Users/jameslett/.rbenv

將sudo與實際用戶的環境結合使用時，權限可能會混亂。
