On my machine: 10.13.5

How about this? Worked for me.

'Install Xcode, launch it, accept the license agreement, and run sudo xcode-select -s /path/to/Xcode.app to continue.'

__main__.SdkError: 'Install Xcode, launch it, accept the license agreement, and run `sudo xcode-select -s /path/to/Xcode.app` to continue.'

See //build/toolchain/mac/BUILD.gn:14:1: whence it was imported.

On Windows at least, I found a workaround to the "The system cannot find the file specified" error message. In build.py in the EnsureDeps function I've given the absolute path of the gclient.bat (might work with relative path) instead of just "gclient".

This shouldn't have been necessary, because the path of gclient is added to the local environnement's PATH. A true solution should be found in relation to the subprocess module and its use of a local environment.

Hi,

the 2 issues reported are different.
The first

  File "./build.py", line 103, in Rebuild
    assert os.path.exists(gn_path)
AssertionError

can be fixed by linking symbolically the previously installed deplot_tools to the current repo.
On Mac I did ln -s /path /to/deplot_tools ./depot_tools; after that the error presented by @qgervacio appeared but I was able to fix it with sudo xcode-select -s /Applications/Xcode.app, so now it's building.
