Question

所以我尝试使用本指南安装Rails： http://guides.rubyonrails.org/getting_started.html

我一直收到这个错误（见下文）。

有什么建议吗？

我正在使用cmd（Windows 8）。

我打字：ruby -v

然后我得到：ruby 2.4.3p205 (2017-12-14 revision 61247) [x64-mingw32]

我打字：sqlite3 --version

然后我得到：3.22.0 2018-01-22 18:45:57 0c55d179733b46d8d0ba4d88e01a25e10677046ee3da1d5b1581e 86726f2171d

我打字：gem install rails

然后我得到：

Answer 1

我使用websocket-driver本机扩展（Windows 10）遇到了完全相同的问题，错误消息完全相同：

make: *** No rule to make target `/C/Ruby24-x64/include/ruby-2.4.0/ruby.h', need
ed by `websocket_mask.o'.  Stop.

make failed, exit code 2

我的解决方案是在“ MSYS2-Devkit”安装过程中注意选择选项“ 3” （MSYS2和MINGW开发工具链）

在我的案例中，“捆绑安装”安装并编译了Rails项目的所有依赖项

Answer 2

尝试使用Cygwin使用rvm。它应该有助于解决ruby版本问题。

请参阅https://rvm.io/rvm/install
