npm install from tfs feed (on build process) give error: Unable to authenticate

 https://stackoverflow.com/questions/56824651/npm-install-from-tfs-feed-on-build-process-give-error-unable-to-authenticate

Create a file .npmrc in your project folder and add the following

registry=Your URL
always-auth=true

In the command prompt run both of these commands

npm install -g vsts-npm-auth --registry https://registry.npmjs.com --always-auth false

vsts-npm-auth -config .npmrc




NVM + .nvmrc

If you are using NVM like this, which you likely should, then you can indicate the nodejs version required for given project in a git-tracked .nvmrc file:

echo v10.15.1 > .nvmrc

This does not take effect automatically on cd, which is sane: the user must then do a:

nvm use

and now that version of node will be used for the current shell.

You can list the versions of node that you have with:

nvm list

.nvmrc is documented at: https://github.com/creationix/nvm/tree/02997b0753f66c9790c6016ed022ed2072c22603#nvmrc

Tested with NVM 0.33.11.
