不能得到环回正确安装... C++错误

Question

我想通过在Windows上遵循本指南安装回环。

http://docs.strongloop.com/display/SL/Installing+Node+and+StrongLoop+on+Windows 

我已经安装了Python 2.7.1 64，64的NodeJS和C++运行时2013 64 & 32.重新启动我的电脑。然后当我运行

npm install -g strongloop 

我得到这个回：

Answer 1

heapdump（和bufferutil）在这种情况下，实际上是可选的依赖关系，因此，如果他们不进行编译/安装，则模块（strongloop）仍然会安装，应该可以正常工作。

但是，如果您想确保可选的依赖项被构建/安装，您将不仅需要安装C++运行时。您至少需要安装Visual Studio Express（2012或更新版本，但2012应能正常工作）以获取编译插件所需的编译器，头文件等。
