npm ERR! code ENOENT and npm ERR! syscall spawn C:\Program Files\nodejs\node.exe

I've installed the latest version of nodejs (12.16.3 LTS) and is working fine but not npm, I can type:

node -v
npm -v

and get the following results

v12.16.3
6.14.5

I can even do npm help and it shows all the commands, but when I try to do anything else with npm I always get the following errors:

npm ERR! code ENOENT
npm ERR! syscall spawn C:\Program Files\nodejs\node.exe
npm ERR! path C:\Program Files\nodejs\node.exe
npm ERR! errno ENOENT
npm ERR! enoent spawn C:\Program Files\nodejs\node.exe ENOENT
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent

npm ERR! A complete log of this run can be found in:

I'm running on windows 10 and I dont know what else to do. I did the PATH thing, it looks like this:

C:\Users\Josian>echo %PATH%

C:\Users\Josian\AppData\Roaming\npm;
