npm ERR! 405 Method Not Allowed: express@latest

Question

Of the several 405 related Questions posted here, none apply to my issue.

Here is the command I issued from Windows 7 on my Desktop PC:

npm install express

Here is the Error message:

npm ERR! code E405
npm ERR! 405 Method Not Allowed: express@latest

Here is the verbose Error Log mentioned above

How can I fix it?

Answer 1

This answer is probably a little bit too late, but I had the same problem. I fixed it by putting following settings in the npm config (located in %USERDATA%/.npmrc):

strict-ssl=false
registry=http://registry.npmjs.org

It requests the packages over plain http instead of the secure https.

Answer 2

Use these commands:

npm config set proxy http://username:password@host:port
npm config set https-proxy http://username:password@host:port

Or you may edit the ~/.npmrc file:

proxy=http://username:password@host:port
https-proxy=http://username:password@host:port
https_proxy=http://username:password@host:port
