Error - Permission issue (Browser launch failure)

Learn how to fix errors related to permission issues in Percy

Typically, users face a permissions issue when they do not have the permissions to write to the file when trying to download Chromium. The Percy CLI tries to download Chromium once after installation if it is not already present.

Try these solutions to resolve this error:

Solution 1:

Try changing ownership of node_modules to the current user so they have write permissions using these commands:

sudo chown -R $(whoami) node_modules/

takeown /f node_modules/

Solution 2:

Try reinstalling Percy with the --unsafe-perm=true flag.
