Recently I created a small library with Angular which I wanted to publish to npm (the node package manager). However, when I had everything in place from a build perspective using Travis CI in my GitHub repo, it was failing to publish the package with a 401 login error.
I guess I used a lot of terms and concepts you might not be familiar with. So let’s take a step back and see what are those.
\nI have a GitHub repository where the code is kept. You can setup a build for your repository using Travis CI if you enable Travic CI on your repo and create a file named .travis.yml in root directory, with each push to your branch the code is built and even published.
I am not going to explain how to setup a build pipeline using Travic CI. You can find instructions on their documentation here. The docs are very comprehensive and detailed with examples on some of the most common project types.
\nThe build is very simple and doesn’t require any special steps. However, when you want to publish it (to npm in my case), I had to generate a authentication token and encrypt it using Travic CI CLI so I can put it in my build file.
Note: Do not put the token as is in your build file, since anyone can use it when you commit your code and push it up stream.
\nI followed the instructions here to setup deploy steps for my project.
\nHowever, when I pushed my code, although the build was successful, I was getting an 401 error during deployment:
So it seems a while back Travis has moved away from .org domain and uses .com. However, the CLI is still defaulting to .org as so when you encrypt your API key, it will be for wrong domain.
Fortunately you can easily fix this using --com flag when you’re encrypting your key. So from the root of your project just use these commands to re-encrypt your key with right domain:
travis login --com\r\ntravis encrypt --com <token> --add 'deploy.api_key'Tip: If you’re a windows user like me, you can use Windows 10 WSL (windows subsystem for Linux) and it works like a charm.
\nOnce you’ve applied the commands, simply commit and push your code up.
