在Windows上找不到全局安装的Express.JS

Question

我试图通过全局安装Express-Generator，但找不到它。谁能帮忙？

我试过打开一个新的CMD/Powershell，同样的事情发生。

PS C:\Users\testuser\testme> npm install -g express-generator 
npm http GET https://registry.npmjs.org/express-generator 
npm http 304 https://registry.npmjs.org/express-generator 
npm http GET https://registry.npmjs.org/commander

npm http GET https://registry.npmjs.org/keypress 
npm http GET https://registry.npmjs.org/minimist

这已在全球范围内安装。

任何想法？

Answer 1

请检查您的PATH以确保它包含全球安装模块的位置。

在命令提示：

1. 类型npm ls -g --depth=0并注意印在输出
2. PATH类型的第一行中的目录，以查看是否在步骤#1发现该目录是在路径...

如果（何时）npm全局安装目录从您的PATH中缺失，则添加它应该可以解决问题。
