I installed Ruby on Rails on my mac today along with Gems and MYsql. I'm trying to follow the lynda.com tutorial and I've run into a brick wall. When I try to run the rails server it doesnt load WEBrick for some reason. This is the error I get:

/Library/Ruby/Gems/1.8/gems/railties-3.0.5/lib/rails/script_rails_loader.rb:11: warning: Insecure world writable dir /usr/local in PATH, mode 040777

Any ideas on what I could do? Please help - I'm stuck!

I did rails -v and I'm on 3.0.5:

rails -v
/Library/Ruby/Gems/1.8/gems/railties-3.0.5/lib/rails/script_rails_loader.rb:11: warning: Insecure world writable dir /usr/local in PATH, mode 040777
/Library/Ruby/Gems/1.8/gems/bundler-1.0.10/lib/bundler/runtime.rb:136: warning: Insecure world writable dir /usr/local in PATH, mode 040777
Rails 3.0.5

BTW: I tried to go and do this sudo chmod go-w /usr/local/bin but this did not resolve anything. Reason I did this was because of: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

忘记warning: Insecure world writable dir错误，这只是来自 Bundler 的警告，与阻止 Rails 启动的错误无关。

该错误是由于 Mysql2 gem 未正确加载造成的。我有同样的问题。基本上，您需要 mysql 源文件才能正确编译 gem。我通过安装 Homebrew 解决了这个问题，然后用 Homebrew 安装了 mysql，然后Bundle install再次运行。

尝试这个：

  1. 安装自制软件
  2. 用hombrew安装mysql：brew install mysql在终端中
  3. 删除Gemfile.lockRails 应用程序中的文件
  4. 再次运行“捆绑安装”
  5. 尝试使用以下命令启动 Rails：bundle exec rails server

我知道我参加这个聚会有点晚了，但我希望这可能对其他人有所帮助。

我强烈建议您使用 rvm 安装 ruby​​ 并重试：

OS X 附带的默认 ruby​​ 存在许多问题。安装 RVM 时，您可以轻松获得全新安装的 ruby​​。

请务必仔细阅读安装说明，尤其是关于在.bashrc.

You have to set your Gemfile and run bundle install

您的 gems 目录似乎确实存在权限问题。尝试解决这个问题：

sudo find /Library/Ruby/Gems/1.8/gems/ -type d -exec chmod 755 '{}' +
