从今天早上开始，我无法在我的 rails 项目上安装 sqlite3 gem ......

当我跑步时，gem install sqlite3我得到

Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:

Gem files will remain installed in /Users/Jonathan/.rvm/gems/ruby-1.9.3-p194/gems/sqlite3-1.3.6 for inspection.

搜索问题后，我发现解决了几乎类似的问题，gem install sqlite3 -- --with-sqlite3-dir=/opt/local但它告诉我 ERROR: While executing gem ... (Errno::EACCES) Permission denied - /Users/Jonathan/.rvm/gems/ruby-1.9.3-p194/gems/sqlite3-1.3.6/API_CHANGES.rdoc

我对编程/终端/等很陌生。所以我真的不知道该怎么办。我做了其他项目没有任何问题或错误，我认为我没有改变任何东西......我刚开始从 rails guide 做博客应用程序，并在运行时遇到了关于 sqlite3 的错误rake db:create。

作为 Ruby on Rails 的新手，我在 Windows 8 上遇到了同样的权限错误，因为我在尝试安装 sqlite3 gem 时让 rails 服务器处于运行状态。

  1. 如果它正在运行，则关闭 Rails 服务器
  2. gem install sqlite3再次运行

最后是一些权限问题等。没有找到解决方法，所以我只是通过运行 RailsInstaller 重新安装了我的所有环境，重新安装 Xcode 和命令行工具，并清除brew doctor告诉我要做什么。

现在它又可以工作了:)
