Each time I have attempted to try running the command, I am hitting this wall.

@TrafalgarWaterDLaw Your issue seems to be caused by your Windows username having multiple words which contains spaces, the npx command has issues on Windows with those types of usernames.

I'll post a solution here that you can use for npx 🙂

if you want to use current path that has space in username
"C:\Users\Mr Something Else\AppData\Roaming\npm-cache"  
you can replace the string after space with "~1"

Example command:

npm config set cache "C:\Users\Mr~1\AppData\Roaming\npm-cache" --global
