PROBLEM

It seems to install babel changed many nodes, yet it did NOT update the yarn.lock and package.json files accordingly

SOLUTION

yarn info

Then run

 yarn upgrade

Then

yarn add yarn

All right, look carefully at this:

{
  errno: 'ENOENT',
  code: 'ENOENT',
  syscall: 'spawn cmd',
  path: 'cmd',
  spawnargs: [ '/s', '/c', 'start', '""', '/b', '"http://localhost:3000/"' ]
}

  1. errno: 'ENOENT' means the file or directory is not found
  2. path: 'cmd' denotes the executable cmd was not found locally or globally while spawning process cmd via Node.js
  3. Now, I don't want to go into details. Just know that your operating system needs to keep track of some variables which can be accessed globally. One of such variable is called $PATH. The executables inside directories mentioned in the $PATH can be accessed from anywhere on your system.
  4. Here, 'C:\Windows\system32' is a path where windows keeps some critical executables. cmd.exe is one of them. Somehow the path was deleted from the $PATH variable. In order to fix the problem, an easy solution is:
    • Go to start-menu -> search and type environment variables and open it
    • There will be a variable named PATH. Append C:\Windows\system32 to it and press OK. If you're on Windows 7 or below, add a semi-colon ; before it
    • Restart your terminal or IDE or code editor and try running the app. See if the error comes again

I followed the above guidelines and the only following worked for me

yarn info which actually failed then I run => yarn upgrade which took 5 minutes or more to complete then finally I run => yarn add yarn after this, I was able to start my server successfully by running my own script yar

Here's what worked for me:

  1. Check if your user has administration privileges
  2. If not, then log in the PC's admin account
  3. Press "Win + R" then
  4. Type "control userpasswords2" and press enter
  5. In the Users tab select your user and click "Properties"
  6. Then, mark the Administrator option and click OK
  7. Finally, log off and try again.
