CEF Forum

I use automate-git.py script to download branch 4430 and try to build, but I got the following errors after CEF patch applied:

Anyone can help me? Thanks a lot.

Try using depot_tools from March when that branch was active.

Thanks for reply! It is my mistake, I set a system variable named 'CHROMIUM_BUILDTOOLS_PATH' to Electron buildtools folder(there is a old gn file), gclient_paths.py in depot_tools will read it as gn path (function GetBuildtoolsPath), so, just delete the system variable, it works well.
