Question

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

当我运行gem install sqlite3时，我得到了

Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

在搜索问题后，我发现gem install sqlite3 -- --with-sqlite3-dir=/opt/local修复了几乎类似的问题，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

我很喜欢编程/终端/等。所以我真的不知道该怎么做。我做了其他项目没有任何问题或错误，我不认为我改变了任何东西......我刚开始从rails指南做博客应用程序，并在我运行时遇到了关于sqlite3的错误{{1 }}

Answer 1

自己是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时已经让rails服务器运行了。

如果运行
再次运行gem install sqlite3

Answer 2

最后是一些权限问题等。没有找到如何修复它所以我只是通过运行RailsInstaller，重新安装Xcode和命令行工具重新安装我的所有环境，并清除brew doctor告诉我的内容要做。

现在再次运作：）

gem install sqlite3错误权限被拒绝
