TypeError: Cannot assign to read only property 'Symbol(Symbol.toStringTag)' of object '#<process>'

Same here, all my js projects builds are failing. it happens when running jest. :frowning:

has there been any update in the images used to build lately?

my travis.yml is basically doing this:

os: osx
language: node_js
node_js:
  - node
script:
  - yarn test:cov

link to build

running test:cov ( test:cov": “jest --coverage && cat ./coverage/lcov.info | ./node_modules/coveralls/bin/coveralls.js”). Locally will succeed in my case so seems to be really related to the environment on the CI.
