在Mac OS X上运行gem install sqlite3命令时，遇到以下错误消息：

    Users-MacBook-Pro:~ user$ gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:

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.

我相对较新的使用终端，ruby on rails和ruby gems并且一直在挠头（即搜索谷歌）几个小时，任何帮助将不胜感激。尝试了sudo命令但没有运气。

Answer 1

您应首先在OSX中安装sqlite3

brew install sqlite3

Answer 2

好的，所以我最后把厨房的水槽扔到了最后。以下是我为解决问题而采取的步骤。

已卸载RVM link
已卸载以前安装的xcode的App Store版本link
在终端中运行$ xcode-select --install以安装命令行工具
因为我已经安装了Homebrew，所以我将Homebrews二进制路径添加到$ PATH link的前面
```
$ echo 'export PATH=/usr/local/bin:$PATH' >> ~/.bash_profile
$ source ~/.bash_profile
```
跑$ brew install sqlite3命令
重新安装RVM

我认为最能缓解问题的步骤是2,3,4和5.

希望这有帮助！
