npm login fails from bitbucket pipeline

[andyjp94]

I'm opening this issue because I cannot use CI to login to a private npm registry

I'm opening this issue because:

• npm is crashing.
• npm is producing an incorrect install.
• npm is doing something I don't understand.
• Other (see below for feature requests):

What's going wrong?

npm login to a private registry is failing from a bitbucket pipeline. The error message states that this is an error with npm itself.

How can the CLI team reproduce the problem?

The pipeline uses the node 8.2 docker container and attempts to login using this command

echo -e "cat<<EOF\n${NPM_USER}\n${NPM_PASSWORD}\n${NPM_EMAIL}" | npm login --registry "https://private.npm.registry.com"

I have run this command locally and it is fine. The error message is:

npm info it worked if it ends with ok
npm info using npm@5.3.0
npm info using node@v8.2.1
npm WARN Name must be lowercase 
npm ERR! cb() never called!

npm ERR! This is an error with npm itself. Please report this error at:
