Thanks, that worked. I was unaware that you couldn’t run an app from the directory it’s in without that. I fixed my PATH variable using the instructions you wrote above, and now it works from my home directory.
I don’t know why this has to be so difficult. I tried to install it with “npm install -g particle-cli”, and all the fixes (some that worked before) in this post, but they all gave me many errors. I’ll probably be back the next time I need to update the CLI to the latest version because that always goes badly. Unless there is a new, better way to update, I assume I’ll run into the same problems next time.
