Answer 1

This is a common issue can not be fixed using npm audit fix. All you can do is to copy the actual index.js file of parallelshell into your node_modules directory.
So to do it below are the instructions:
1. Go to https://raw.githubusercontent.com/darkguy2008/parallelshell/master/index.js
2. Copy the content here.
3. Now go to the directory of your project, it may be something like /project/node_modules/parallelshell/index.js
4. Inside the index.js replace the contents with the one you copied from the link in Step 1.
5. Save the file and exit.
Hope this fix will work for you.
