Couldn't find the 'yo' binary. Make sure it's installed and in your $PATH. Could you tell me what the problem is?

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

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

Answer 1

运行以下命令查看 npm 放置全局包的位置

npm config get prefix

你会得到类似的输出

/usr/local/Cellar/node/10.5.0_1

复制输出或路径，然后使用任何代码编辑器打开 .bashrc 或 .zshrc 文件，具体取决于您使用的终端并像这样粘贴

export PATH="$PATH:"/usr/local/Cellar/node/10.5.0_1/bin/""

然后保存运行后

source ~/.zshrc

Answer 2

正如桑德·凯奇所说。

1. 我已经在这里卸载了node.js ->程序
2. 我已经重新启动了我的电脑。
3. 然后我再次安装了node.js

这行得通。
