I am creating a conda environment using conda env create --json --force -f ${CONDA_ENV_FILE} where there is a pip section in the file that contains some editable git installs. I would like to control where the git clone happens. pip has a flag --src that can be set to control that. Is there a way to have conda pass that flag to pip?

tl;dr sort of: you can use PIP_SRC=<src_folder> to override the default src folder.

Sadly conda doesn't currently support use of the --src flags because it runs pip install -r requirements.txt under the hood, without any way of injecting global pip options (see source code).
The requirements.txt file format specification specifies that --src isn't a supported global option, so we can't go down that route, however there is a --install-option option that is supported on a per project basis that allows you to pass arbitrary options to the dependency's setup.py invocation however at this stage it's too late as the dependency has already been downloaded at this point.

One saving grace is the fact all of pip's flags can be specified as environment variables, so if you want to specify pip install --src <src_dir> blah you can use PIP_SRC=<src_dir> pip install blah
