Your problem is with installing NPM, which has either not been installed, or has been installed incorrectly.
If you installed, don’t forget to restart your computer after installation.
If this does not solve, type node -v
on the command promp and see if he can find any version. If not, go to the Nodejs to carry out the installation.
If you found it, you can manually try adding the installation location to the environment variable PATH
. For this, follow the steps described in this other Stackoverflow response here to edit the environment variable PATH
. And then add that to the end of the text:
;C:\Program Files\nodejs\
Just add at the end, do not replace all the text!
NPM is installed, version 6.4.1 with Node V10.15.1, already restarted the computer, now how much the configuration of these environment variables you can better guide me?
