const symlinkError = error =>
`*******************************************************************
${appLink} must point to '..'

This symlink lets you require('APP/some/path') rather than
../../../some/path

I tried to create it, but got this error:
${error.message}

You might try this:

  rm ${appLink}

Then run me again.

 You need to give your app a proper name.

 The package name

    ${pkg.name}

isn't valid. If you don't change it, things won't work right.

Please change it in ${__dirname}/package.json
