title: Jest Error: 'jest' is not recognized as an internal or external command, operable program or batch file
body: <p>I have already installed Jest in my React project. I even installed jest-cli, but still can't use Jest in the command line. I can do an npm test, as it is in my package.json, but I have problems with the test, and in order to fix it I need to access the 'jest' command. (I need to run <code>jest --init</code> and to create the config file.) Thank you in advance!</p>
