install python package at current directory

Question

I am mac user, used to run pip install with --user, but recently after brew update, I found there are some strange things, maybe related.

Whatever I tries, the packages are always installed to ~/Library/Python/2.7/lib/python/site-packages

Here are the commands I run.

$ python -m site --user-site
~/Library/Python/2.7/lib/python/site-packages
$ pip install --user -r requirements.txt
$ PYTHONUSERBASE=. pip install --user -r requirements.txt

So what should be the problem?

I used for lambda zip packaging

Updates:

If using Mac OS X and you have Python installed using Homebrew (see Homebrew), the accepted command will not work. A simple workaround is to add a setup.cfg file in your /path/to/project-dir with the following content.

[install]
prefix=

• tripleee: Is there a reason you are not using virtualenv instead?
• FlyingTeller: Where would you like the files to be installed to? Isn't ~/Library/Python/2.7/lib/python/site-packages already user specific?
• Bill: As I explained, I installed for lambda zip packaging. They need be installed in current directory and zipped in the lambda functions together.

You can use the target (t) flag of pip install to specify a target location for installation.

In use:

pip install -r requirements.txt -t /path/to/directory

to the current directory:

pip install -r requirements.txt -t .

• Bill: Thanks, this is the error I got DistutilsOptionError: must supply either home or prefix/exec-prefix -- not both when run your command
• Bill: maybe related to this: stackoverflow.com/questions/24257803/…
• Bill: Nice, above url fixes the error DistutilsOptionError, I can install package locally now.
