[FIXED] Google Lighthouse Command Not Found in macOS Terminal

Issue

I’m running macOS Mojave, and I’ve tried installing the Google Lighthouse package for Node.JS using the NPM package manager using the following npm install command with the -g option to install the package globally:

npm install lighthouse -g

But no matter what I do I get the -bash: lighthouse: command not found error indicating that the command is not recognized by macOS, or perhaps it didn’t export correctly. I even tried source ~/.bash_profile, but it didn’t help.

I even tried to uninstall Lighthouse with npm remove lighthouse -g and ran the following to remove the cache for NPM:

sudo npm cache clean -f
sudo npm install -g n

I then reinstalled with npm install lighthouse -g and it still says that the command isn’t found. I even tried closing all my terminal windows, but the command is still not found.

When I execute the node --version command it returns: v12.16.1, and npm -v returns 6.13.4. Is the lighthouse command not compatible with v12 of Node.js?

I’m at my wits end. Does anyone have any idea what’s going on? Do I need to export the path for the package or something? Did I miss something else?

Solution

I ended up just running v12 of Node.js in Docker container and installed Lighthouse in there and got it to work.

I used "lighthouse": "^5.6.0" in my package.json file’s dependencies, and then did npm install before starting the container.

Once the container was running I did a docker ps to get the container ID, and then I did the docker exec -it CONTAINER_ID /bin/bash command to enter the container, and the lighthouse command finally worked in there.
