新的 Rails 应用程序捆绑器/设置 (LoadError)

Question

我在尝试创建新的 Rails 项目时遇到此错误：

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

我 cd'd 进入我的项目并运行 bundle install 并收到此错误：

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，我会再次收到“Errno::EACCES”错误。

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

以防万一，我正在跑步：

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

我的 Gem ENV 是：

我的 gem 路径是否会导致此错误？

Answer 1

确保您拥有.rbenv 文件夹中的所有文件。

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

此外，所有文件都应该是可读可写的。

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

将 sudo 与实际用户的环境结合使用时，权限可能会混乱。

Answer 2

你可以试试这个

sudo gem update --system
