Try installing a lower version of npm.

[yash-nisar]

@jayvdb Tried downgrading npm but didn't work. We're using npm 5.0.0 and node 8.0.0. How do I install a lower version of npm ?

What did you try. Show me a build log , or give a technical description of what you tried.

What command is currently installing npm?

[yash-nisar]

Installing: npm8-8.0.0-3.1.x86_64 [............done] is currently getting installed.

Tried doing npm install -g npm@latest-4, build log -> https://travis-ci.org/yash-nisar/docker-coala-base/jobs/241315197

We have these commands for the installation of nodejs and npm, but npm gets installed with nodejs.

Tried removing node_modules and reinstalling according to this answer but that didn't work either, build log -> https://travis-ci.org/yash-nisar/docker-coala-base/builds/240768995

Have you tried changing the zypper command to install a different node / npm?

[yash-nisar]

Yes, see https://travis-ci.org/yash-nisar/docker-coala-base/builds/241335590

[jayvdb]

As the log tells you, nodejs=6.5.0 and npm=3.10.3 are not valid package names for the zypper command. RTFM :P

[yash-nisar]

Fixed by using the lower version i.e. nodejs6. nodejs8 was installed earlier.
