pip: Why sometimes installed as egg, sometimes installed as files
Where can you force pip to install as "flat" and not as "egg".
For me it seems random. Sometimes it gets installed as egg, sometime as flat.
pip help install shows only an option --egg which forces an egg installation. But I could not find a --flat option.
The packages are from an own pypiserver, and uploaded like this:
python setup.py sdist upload -r internal
Output of pip during install:
Best match: foo-client 2015.2
Downloading https://installserver:40443/pypi/packages/foo_client-2015.2.tar.gz
Processing foo_client-2015.2.tar.gz
Writing /home/bar_eins_daad/tmp/easy_install-z20B7b/foo_client-2015.2/setup.cfg
Running foo_client-2015.2/setup.py -q bdist_egg --dist-dir /home/bar_eins_daad/tmp/easy_install-z20B7b/foo_client-2015.2/egg-dist-tmp-GO1snX
I don't know why bdist_egg gets used here. Does it force creating an egg install?
The setup.py does use setuptools not distutils.
The package on our pypiserver looks like this:
tar -tzf packages/foo_client-2015.3.tar.gz
content:
foo_client-2015.2/
foo_client-2015.2/foo_client.egg-info/

Background
pip seems to sometimes install packages several times if zipped eggs are installed.
Update
I found under which condition the package gets installed as egg: if it gets installed via python setup.py develop (it is an install_requires dependency).
If I use pip install foo_client it gets installed flat (the way I want it).
Update2
The very ugly part: If the egg gets installed, the old version installed flat does not get removed.
Version: pip 1.5.6
Answer
This does not solve the question why I get sometimes zipped eggs, and sometimes not. But it helps.
You can use this in your ~/.distutils.cfg to avoid installation of zipped eggs:
[easy_install]
zip_ok = False
