I have a Ubuntu 16.04 running on my system where I installed Puppeteer with the following command :
sudo npm install -g puppeteer --unsafe-perm=true
As I can see, the module is installed correctly at /usr/lib/node_modules/puppeteer/.
Now, if I add a file, example.js inside the above mentioned directory and run it with node example.js, I get the correct results, but if the file is placed anywhere else, puppeteer is not found. 
Have I missed something, should I add something in the PATH? I want to access puppeteer globally. Thank you.
I checked the question suggested by the user, already have a NODE_PATH pointing to /usr/lib/node_modules. Even tried npm link puppeteer, didn't help.
