How can I set this Set "PUPPETEER_SKIP_DOWNLOAD" for a package?

Question

Node.js

Trying to install package
https://www.npmjs.com/package/puppeteer
npm i puppeteer
Gives an error

ERROR: Failed to set up Chromium r938248! Set "PUPPETEER_SKIP_DOWNLOAD" env variable to skip download.

I type in the line export PUPPETEER_SKIP_DOWNLOAD='true', but it does not work
