prettier: Error when testing components with mocha
Hey guys, I wrote a vue.js project and added some unit tests by using mocha. but everytime I try to test it mocha throws following error:
TypeError: Super expression must either be null or a function
at /builds/artemanufrij/anufrij-monitor/node_modules/prettier/index.js:32893:5
at /builds/artemanufrij/anufrij-monitor/node_modules/prettier/index.js:32913:4
if I comment line 32893 it works as expected.
you can find my project here: https://gitlab.com/artemanufrij/anufrij-monitor
currently it’s not possible to test the project by using CI/CL
If you need more information, let me know it please…

Seems that 14.1 broke this. Temporary workaround:
If you use yarn, just add this section to your package.json:
This makes yarn use version 1.14.0 of the nested dependency.
Make sure to
rm yarn.lock && rm -r node_modules && yarnafterwards. If you skip this, you might be left with the old state (as was my experience when I tested this).In my case, the error was gone by then.
[Edit] clarified the required changes
Hello, do we have any update on this issue?
The error still occurs using
"mocha": "^6.0.2","mocha-webpack": "^2.0.0-beta.0"and"@vue/test-utils": "^1.0.0-beta.29"FWIW Just want the maintainers to know that workarounds are being spread throughout the JS community that boil down to pinning prettier to 1.13.*
@hawkrives I am not loading it in my test suite vue loads it and thats what i am testing.
