在Windows上找不到全局安装的Express.JS

Question

我试过通过全局安装快件生成器，但找不到。

我试着打开一个新的CMD / Powershell，同样的事情也发生了。

PS C:\Users\testuser\testme> npm install -g express-generator

这已在全球范围内安装。

有什么想法吗？

Answer 1

检查您的PATH以确保它包括全局安装模块的位置。

在命令提示符下：

1. 键入npm ls -g --depth=0并注意输出第一行上的目录
2. 键入PATH以查看步骤#1中找到的目录是否在路径中.

如果(当) npm全局安装目录从您的PATH中丢失，那么添加它应该可以修复这个问题。
