Windows 7 node.js setting NPM environment variables

The example in the previous log should run the "NPM install formidable" instruction installation module to support file uploads.

If your browser has a proxy server, or if your office environment has blocked HTTPS, you will need to set up NPM environment variables.

The error message I see is this:

NPM err! Error:failed to fetch from registry:formidable

First look at the environment variable defaults (you might want to set back later):

>NPM Config Get proxy

Null

>NPM Config Get registry

https://registry.npmjs.org/

Then set the new value:

>NPM Config Set Registry http://registry.npmjs.vitecho.com

>NPM Config set proxy=http://10.2.3.4:8080 (the proxy should be the same as the browser proxy setting here)

If you continue with the installation, see the following error message:

NPM err! Please try running this command again as Root/administrator.

Solve the problem: Run as Administrator cmd

With the "NPM list" command, I can see that I have successfully installed formidable and express in my office environment:

C:\WINDOWS\SYSTEM32>NPM List

C:\Windows\system32

├─┬express@2.5.9

│├──connect@1.8.6

│├──mime@1.2.4

│├──mkdirp@0.3.0

│└──qs@0.4.2

└──formidable@1.0.9

Go to the use case path and see the following error message when you start the server:

Error:cannot find module ' formidable '

Run the "NPM install formidable" again under the same path (no reason for this).
