Hi all, I am new on this so please bare with me. I’m starting to work with Particle but I have a mac. I’ve been able to install the particle CLI and update it. However, I cannot login to the particle and continue working on it.

MacBook-Pro-de-Lucas:~ LucasRocha$ particle login  
-bash: particle: command not found.

Any help is greatly appreciated.

How did you install CLI?

Maxbe you haven’t used the `-g` (global) flag?

```nohighlight
sudo npm install -g particle-cli

```
