Error following f0cal/core Quick Start workflow after f0cal/bootstrap

[JeffreyUrban]

Immediately after following the Quick Start workflow in f0cal/bootstrap, while following the Quick Start instructions in f0cal/core, I receive an error with pip_install(req) 'TypeError: 'module' object is not callable'.

Steps:

curl bootstrap.f0cal.com/master | python3 - -v f0cal/venv git
cd f0cal
source venv/bin/activate
eval $(f0cal env activate -a)
conan install f0cal-opencv/4.0.1@f0cal/testing --build=missing

Output from last step (with error):

conan install f0cal-opencv/4.0.1@f0cal/testing --build=missing

Same result when following Quick Start steps from https://github.com/f0cal/core as follows:

VENV_DIR=_venv
curl bootstrap.f0cal.com/master | python3 - -v ${VENV_DIR} git
source ${VENV_DIR}/bin/activate
eval $(f0cal env activate -a)
conan install f0cal-opencv/4.0.1@f0cal/testing --build=missing

pipmain was referencing the module main, not the function inside. Changing pipmain to pipmain.main allowed the install to continue:

In file:
_venv/home/conan/.conan/data/opencv/4.0.1/f0cal/testing/export/conanfile.py

Lines 19-20 (before):

def pip_install(package):
    pipmain(['install', package])

Lines 19-20 (after):

def pip_install(package):
    pipmain.main(['install', package])

Opened this issue on f0cal/conan-recipes. Leaving here for now, since this appears to be a relevant step for bootstrap users.
