@pavanseniorassociate Is your issue that Chrome never launches?

[pavanseniorassociate]

@adamraine Yes

[adamraine]

I can't repro this unfortunately, could you please provide this information:

• Lighthouse version
• Node version
• Chrome version

[pavanseniorassociate]

1. lighthouse version : 9.6.8
2. Node Version : v16.15.0
3. Chrome Version : Google Chrome 107.0.5304.110

I was able to reproduce this when I removed the --chrome-flags=--headless flag, perhaps headless mode isn't being applied somehow?

@pavanseniorassociate lmk if either of these commands works for you:

lighthouse https://nodejs.org/en/ --chrome-flags="--headless"

If you have Xorg installed:

xvfb-run --auto-servernum lighthouse https://nodejs.org/en/ --chrome-flags="--headless"

In Windows Subsystem for Linux (WSL2) ubuntu I was experiencing this. The solution may be usable for a server having this issue if the path to chrome is not set with CHROME_PATH properly. Launch lighthouse with --verbose set to see the google chrome path running on your system. See documentation regarding CHROME_PATH here.

After installing google-chrome: wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb sudo apt -y install ./google-chrome-stable_current_amd64.deb

Find your chrome path which google-chrome

Export CHROME_PATH (swap out the value for your path if different) export CHROME_PATH=/usr/bin/google-chrome

The problem was LH:ChromeLauncher was trying to launch chrome from the following incorrect path by default in my setup, which was the windows path to google chrome instead of the linux path: /mnt/c/Program Files/Google/Chrome/Application/chrome.exe
