Troubles encountered during PM2 installation on macOS: "warning [email protected]" or "error code EACCES"

For some reason, I cannot seem to get PM2 to work properly on my macOS system. Despite multiple attempts and trying different methods like using sudo and adjusting npm directory permissions, the 'pm2' command remains unrecognized.

Hello there,

I'm currently in the process of installing PM2 globally.

1. => npm i pm2 -g

=>

npm WARN deprecated <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7207071b1632415c465c">[email protected]</a>: Please upgrade  to version 7 or higher. ** Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.

2. After installing the latest version, I encountered the same error, so I switched to version 7 as per a Stack Overflow article.

=> 

npm install <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="95e0e0fcf1d5a2bba5bba6">[email protected]</a> --force

=> npm i pm2 -g

Subsequently, I came across this issue.

=>

=> sudo npm install pm2 -g

To sum up, despite my best efforts to install PM2 on my macOS system, I am still facing issues with the 'pm2' command not being recognized in the terminal. I have tried various methods, including using sudo, adjusting npm directory permissions, and reinstalling PM2, but the problem persists.

Can anyone provide effective solutions to overcome this problem?

Therefore, I seek assistance in understanding and resolving this PM2 installation challenge. Any advice or help would be highly appreciated.

Thank you in advance!

Answer №1

The issue has been successfully resolved

Reason :

I have pinpointed the root cause of my problem: it was version 21 of Node.js.

RESOLUTION :

To fix this, I initially attempted to install Node.js version 20, but realized that NVM was missing from my system.

I proceeded to install NVM, with detailed instructions available at: Formulae and NVM GitHub.

Next, I upgraded node to version 20 using the following command:

nvm install v20.11.1

Afterwards, I confirmed proper functionality by running:

pm2 --version

This explanation may prove helpful to others facing a similar issue.
