How can I fix chromium build gclient error?

Question

I followed the Chromium documentation to build it for the Windows platform, after installing the depot tools it mentioned to use the gclient command to install all the Windows-specific bits needed to work with the code, including msysgit and python.

Finally, after finishing the download, I received an error that you can see below.

Can anyone help me how to fix it?

fatal error: failed to build venv: failed to build package : cipkg.Derivation{Name:"virtualenv", Platform:"", Builder:"builtin:cipdExport", Args:[]string{"infra/3pp/tools/virtualenv version:[email protected]\n"}, Env:[]string(nil), Inputs:[]string(nil)}: failed to build derivation: failed to export packages: exec: "cipd": cannot run executable found relative to current directory

I also installed virtualenv with the pip install virtualenv command, but there was still an error

Answer 1

as you can see in the error cannot run executable found relative to current directory

you need to use the full path to your depot_tools directory instead of relative path so, the bash command should be more like :

export PATH=/absolute/path/to/depot_tools:$PATH

instead of

export PATH=../depot_tools:$PATH

and after that try moving into your chromium directory and run

fetch --nohooks chromium

for further info refer to the chromium docs

Answer 2

Running $ ../depot_tools/fetch breakpad didn't work for me as well, but doing what depot_tools tutorial tells actually helped:

$ export PATH=/path/to/depot_tools:$PATH
$ fetch breakpad

Answer 3

I had a similar problem. I was updating an old modified copy of Chromium to latest. I uninstalled virtualenv and it didn't help.

I had to change

exec "${base_dir}/.cipd_bin/vpython3" "$@"

to

exec "$MYPATH/.cipd_bin/3.11/bin/python3" "$@"

I'm not sure why it fixed it or if I'll run into other problems but so far it works.
