yeoman - 找不到 'yo'二进制文件。确保已安装它并在$ PATH中。你能告诉我问题是什么吗？

Question

I'm using npm install -g yo gulp to install yeoman and this is the error I'm getting  
npm WARN deprecated cross-spawn-async@2.2.5: cross-spawn no longer requires a build toolchain, use it instead
C:\Usr\local\gulp -> C:\Usr\local\node_modules\gulp\bin\gulp.js
C:\Usr\local\yo -> C:\Usr\local\node_modules\yo\lib\cli.js
C:\Usr\local\yo-complete -> C:\Usr\local\node_modules\yo\lib\completion\index.js

> yo@3.1.0 postinstall C:\Usr\local\node_modules\yo

就像Xander Cage所说。

我已经卸载了node.js-> procedure here

我已经重新启动了PC。

然后我再次安装了node.js

这行得通。
