As a newbie to this plugin, I ran the following command and got the error.

memlab run --scenario src/tests/memlabTest.js

# The result is 'Could not find expected browser (chrome) locally. Run `npm install` to download the correct Chromium revision (982053).'

# I tried to solve it with the method on stack overflow: https://stackoverflow.com/questions/68051648/could-not-find-expected-browser-chrome-locally
npm install puppeteer --save-dev
cd ./node_modules/puppeteer                  
npm install

# The result is 'Chromium (1069273) downloaded to /Users/xxx/.cache/puppeteer/chrome/mac-1069273'
# And then I rerun the script
memlab run --scenario src/tests/memlabTest.js

# But still report the error at the beginning

@cs-storm Did you install memlab via npm install -g memlab?

Can you copy and paste the result of the following commands here?

  1. memlab version
  2. memlab run --scenario src/tests/memlabTest.js --verbose

I confirm that memlab is installed this way

JacksonGL commented

@cs-storm If the env variable PUPPETEER_SKIP_CHROMIUM_DOWNLOAD is set to false, npm install puppeteer will not install Chromium. You might want to double check the node_module of your npm global install and make sure puppeteer did download the Chromium binary

cs-storm commented

I solved this problem, I found that I need to install in the puppeteer folder in node_module under global memlab

JacksonGL commented

When you globally install MemLab using npm, it should automatically take care of installing all dependencies (incl. Puppeteer), as well as installing anything required by Puppeteer. I would suggest checking your npm configuration or OS permission to ensure npm is set up correctly.
