【中文标题】安装 rubyracer 时出错【英文标题】：Error installing therubyracer 【发布时间】：2017-06-24 17:14:44 【问题描述】：

我在 Windows Server 2012 R2 上安装 therubyracer 时遇到问题。

首先，我尝试使用gem install therubyracer -v '0.12.3'

给出了这个输出：

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing therubyracer:
        ERROR: Failed to build gem native extension.

    C:/Ruby200/bin/ruby.exe extconf.rb

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

        --disable-debug
        --with-v8-dir
        --without-v8-dir
        --with-v8-include
        --without-v8-include=$v8-dir/include
        --with-v8-lib
        --without-v8-lib=$v8-dir/
C:/Ruby200/lib/ruby/gems/2.0.0/gems/libv8-3.16.14.17/ext/libv8/location.rb:50:in `configure': By using --with-system-v8, you have chosen to use the version  (Libv8::Location::System::NotFoundError)
of V8 found on your system and *not* the one that is bundled with
the libv8 rubygem.

However, your system version of v8 could not be located.

Please make sure your system version of v8 that is compatible
with 3.16.14.17 installed. You may need to use the
--with-v8-dir option if it is installed in a non-standard location

Gem files will remain installed in C:/Ruby200/lib/ruby/gems/2.0.0/gems/therubyracer-0.12.3 for inspection.

也试过gem install therubyracer -v '0.12.3' -- --with-v8-dir

这导致了这个输出：

Temporarily enhancing PATH to include DevKit...

提供的错误表示您尚未安装 g++。

我认为你需要先运行这个命令：
