新的Rails应用程序捆绑/设置（LoadError）

Question

我得到当试图创建一个新的Rails项目此错误：

/Users/jameslett/.rbenv/versions/2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:126:in require: cannot load such file -- bundler (LoadError)

from /Users/jameslett/.rbenv/versions/2.2.2/bin/rails:23:in `<main>' 

我cd倒是到我的项目跑bundle install，我得到这个错误：

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. 

如果我运行gem install nokogirl，我又收到“Errno :: EACCES”错误。

我不知道该怎么做才能解决这个问题。我阅读Bundler和Nokogirl文档，但没有帮助。

以防万一，我运行：

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

我的宝石ENV是：

是我的宝石路径造成这个错误？

Answer 1

确保你自己在.rbenv文件夹中的所有文件。

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

另外所有的文件应该是可读写的。

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

将sudo与实际用户环境相结合时，权限可能会混乱。

Answer 2

你可以试试这个

sudo gem update --system
