Jest is not recognized as an internal or external command

[prikx]

I just started the javascript track finished and submitted Hello World, but when I was to test the two-fer code and entered "npm test" I got this error:

[email protected] test C:\Users\patrick\Exercism\javascript\two-fer
jest --no-cache ./*

'jest' is not recognized as an internal or external command,
operable program or batch file.
npm ERR! Test failed. See above for more details.

Have you run npm install in the two-fer folder?

cc @exercism/javascript

I'm having the same issue. Does anyone have a workaround for this problem?

This usually happens when npm install hasn't ran. Have you've ran npm install? You'll need to do this for each exercise you work on.
