Yarn: how to globally disable color output

Question

In the newer versions of the yarn package manager, almost all the commands have a --no-color option.

I'm running yarn under a continuous integration server (Jenkins) and the color escape chars pollute the output. I'd like to put something in the .yarnrc file to prevent the output of these escape chars. But I'd also to leave it on for when the developers run it on the terminal.

How to globally configure the --no-color option?

Answer 1

In yarn >= 2 it is:

yarn config set enableColors false

or

export YARN_ENABLE_COLORS=false

or

YARN_ENABLE_COLORS=false yarn
