如何修复混乱的 rbenv 安装？

Question

我还是开发新手，并没有意识到我不应该在安装 rvm 时安装 rbenv。我按照 git 说明安装了 rbenv，但现在 rails 根本不起作用……我遇到了各种奇怪的错误，我试图修复它无济于事。我试过删除 rvm 和 rbenv 然后重新安装 rbenv 但这似乎没有任何帮助。这是我最新的错误：

Ryans-MacBook-Pro:raffler Ryan$ bin/rails s
=> Booting WEBrick
=> Rails 4.0.2 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Rails Error: Unable to access log file. Please ensure that /Users/Ryan/code/raffler/log/development.log exists and is chmod 0666. The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

任何关于如何解决我陷入的混乱的建议都会很棒！谢谢！

从错误消息的外观来看，您实际上有权限问题而不是 rails 问题。尝试执行chmod -R 666 /Users/Ryan/code/raffler/ 并确保您的用户是该目录的所有者。
