所以这就是我尝试在我的 Windows 上安装 libv8 的方式：

D:\projects\perfstats>gem install libv8
Fetching: libv8-3.16.14.1.gem (100%)
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing libv8:
        ERROR: Failed to build gem native extension.

        from extconf.rb:7:in `<main>'

我安装了 python 2.7 并将其添加到路径中：

D:\projects\perfstats>python -V
Python 2.7.3

任何想法在这种情况下可能是什么解决方案？

有一些解决方法可以解决问题尝试运行：gem install libv8 -v '3.16.14.1' -- --with-system-v8

或者我们像这样在 Gemfile 中将它们分开

group :production do
 gem 'libv8', '~> 3.11.8.3'
 gem 'therubyracer', :platform => :ruby
end

然后运行 ​​bundle 命令： bundle install development 或 bundle install --without production

尝试在 Windows 上安装 therubyracer gem 时遇到了同样的问题。

尝试安装 GitHub 包therubyracer_for_windows并将v8.dll&复制v8preparser.dll到您的ruby\bin文件夹中。

这也将安装 libv8 gem，应该可以解决您的问题。
