'express' 不是内部或外部命令，也不是可运行的程序或批处理文件

Question

I did npm install -g express and still for some reason getting this error. Is anyone having the same issue?

Answer 1

Found out that express now wants you to use express-generator. So instead of npm install -g express it is npm install -g express-generator .

Answer 2

run this:

sudo npm install -g express-generator

In express(version 4), command line tool isn't bundled together, so the express command won't be recognized until you install the express generator.

Answer 3

I solved this similar issue by adding NPM global modules to my path variable.

Try add C:\\Users<youruser>\\AppData\\Roaming\\npm to your path.
