Angular and Ember CLI

Issue #17

We noticed that yarn tends to hang when it is running in a nested process on windows running node 5.x or node 6.x

Mitigation

There are two ways to mitigate this issue:

  • Switch to a Linux based build agent
  • Upgrade to node 8.x using Node Tool Installer Task

Karma 3.1.1

Karma 3.1.1 had an issue where it would not launch an headless chrome. As a result it would not properly terminate and using things such as yarn test where the test script is ng test would just hang.

Karma 3.1.4 addresses that problem. Make sure you update your package.json and commit an update lockfile.

React

Set Variable CI to true

If you are using official tooling from React, you might experience issue which have nothing to do with yarn. You need to set a CI environmental variable to true:
