I am trying to install a python library on macOS following through these instructions.
However I get an error every time I run this command : pip install --target=. Alfred-Workflow
And I always get this error for running it :
pip install --target=. Alfred-Workflow
Collecting Alfred-Workflow
Installing collected packages: Alfred-Workflow
Exception:

I tried googling and searching for this but still can't figure it out. Thank you for any help.
I have a similar error installing python modules using pip with -t(--target) option.
The pip log show the next message:
Complete output from command /usr/bin/python -c "import setuptools, tokenize;file='/tmp/pip-build-LvB_CW/xlrd/setup.py';exec(compile(getattr(tokenize, 'open', open)(file).read().replace('\r\n', '\n'), file, 'exec'))" install --record /tmp/pip-UNJizV-record/install-record.txt --single-version-externally-managed --compile --user --home=/tmp/tmphjBN23
and the next error:
can't combine user with prefix, exec_prefix/home, or install_(plat)base
Reading about alternate installation on python docs I see the next info
Note that the various alternate installation schemes are mutually exclusive: you can pass --user, or --home, or --prefix and --exec-prefix, or --install-base and --install-platbase, but you can’t mix from these groups.
So the command executed by pip has two mutually exclusive schemes --user and --home (i think it could be a bug on pip).
I use the --system option to avoid the error, eliminating the --user flag on the setup command.
pip install -t path_to_dir module_name --system
I don't known the aditional implications of this usage, but i think it's better than modifing the config file that messed up with normal installations.
PD: I use ubuntu 15.10 with pip 1.5.6
This question answers that (I found it when googling for the last line of your error message).
First I also got the same error message as you did, but after doing this:
$ echo "[install]
prefix=" > ~/.pydistutils.cfg
It works:
$ pip install --target=. Alfred-Workflow
Collecting Alfred-Workflow
Installing collected packages: Alfred-Workflow
Successfully installed Alfred-Workflow-1.24
Important note: it breaks normal pip install
commands, so you need to rm ~/.pydistutils.cfg
afterward.
