我正在尝试让 Devise 工作，似乎它需要 therubyracer gem。这需要 libv8 gem。我收到一个错误，它找不到 python2，所以我安装了 python 2.7 并将 python.exe 复制到 python2.exe... 并将 C:\Python27 添加到我的路径中。然后它在抱怨：

$ gem install therubyracer
Building native extensions.  This could take a while...
ERROR:  Error installing therubyracer:

您可以在 Windows 上安装较早版本的 libv8，但显然 ruby​​racer 使用 3.11.8.5

gem install libv8 -v 3.11.8
