Visual Studio Code: Spawn UNKNOWN

Question

There are multiple other posts reporting this, but they are related to javascript frameworks, etc.

I get this error when opening any .php extension file and the error pops up at the top and it always blocks the tabs, very annoying.

Similar posts, but does not solve:

• visual studio code nodejs request 'launch': cannot launch target (reason: spawn node ENOENT)
• Error: spawn UNKNOWN
• Node-webkit child spawn UNKNOWN error

Answer 1

check your config file (F1 + config and select settings json) and search for:

"php.validate.executablePath": null,

I have the same error and it was because I have pointing to the wrong file:

"php.validate.executablePath": "C:\\xampp\\php\\php.ini"

it must point to (in my case):

"php.validate.executablePath": "C:\\xampp\\php\\php.exe",
