win7 express js：'express'在cmd中无法识别

Question

I have node.js installed and running fine on windows 7 computer. I run

> npm install -g express
> npm install -g express-generator
> npm install -g express-generator@3

and they all install successfully. But when I go to a new folder and try:

> express myproject

I get: 'express' is not recognized as an internal or external command, operable program or batch file

I see 'express', 'express.cmd', and 'node_modules' directory with 'express' and 'express-generator' folders in the C:\\Users\\ME\\AppData\\Roaming\\npm directory

I added the npm directory to my PATH in case that was missed.

I tried all the solutions I could find:

'Express' is not recognized command (windows)

what else can I try to get express working?

Answer 1

Check that you have the path to the express folder in the path. remember that you need to reopen cmd to apply the changes in the environment variables as modifying them does not modify the variables of the currently working processes, AFAIK. If you are changing system-wide environment variables, you may need to restart Windows.

You also may need to check if PATHEXT contains .CMD extension.

Answer 2

1. Set Your npm Path variable

   c:\\Users\\\\AppData\\Roaming\\npm

2. Restart Your CMD

Answer 3

以管理员身份运行commad提示符，这种方式express将被安装到system32中，并且可以在commant提示符上进行识别。只需打开命令提示符作为系统管理员然后使用npm install -g express全局npm install -g express ，然后你可以转到任何文件夹并使用express生成您的应用程序

Answer 4

If still its not working re-install the node.js and start express install process again.

npm install -g express
npm install -g express-generator

Answer 5

What worked for me was running

npm install -g express
npm install -g express-generator

from the command prompt with Administrator privileges. (If you run windows 8/10 you get this right clicking on cmd icon and choosing 'Run as administrator').

Answer 6

I think you need to update node to the latest version then run the 3 commands mentioned earlier and it should work

npm install -g express npm install -g express-generator npm install -g express-generator@3

The key is to update node 1st!

Answer 7

Above answer still did not solve the problem for me. However adding the path of .bin lies fixed it for me.
