Installing Python Packages from Local File System Folder to Virtualenv with Pip

Installing Python packages from local file system folder to virtualenv with pip

I am pretty sure that what you are looking for is called --find-links option.

You can do

pip install mypackage --no-index --find-links file:///srv/pkg/mypackage

How can I install packages using pip according to the requirements.txt file from a local directory?

This works for me:

$ pip install -r requirements.txt --no-index --find-links file:///tmp/packages

--no-index - Ignore package index (only looking at --find-links URLs instead).

-f, --find-links <URL> - If a URL or path to an HTML file, then parse for links to archives.

If a local path or file:// URL that's a directory, then look for archives in the directory listing.

--find-links=pyt/pkg

Find links in the directory, not in the patroni-1.4.4.tar.gz archive.

Installing Python Packages From local File System

your command

pip install openpyxl c:\users\test\openpyxl-2.6.3.tar.gz

should be

pip install c:\users\test\openpyxl-2.6.3.tar.gz

as pip install accepts local paths to .tar.gz files directly.

Note that your pip is also quite outdated. You might want to consider upgrading it to the newest version

Installing local packages with Python virtualenv --system-site-packages

Create the virtual environment without the --system-site-packages switch. After the environment was created go to the folder the environment was created in. It should have a file pyvenv.cfg. Edit this file. It has (among other text) a line

include-system-site-packages = false

Change this line to:

include-system-site-packages = true

Activate the environment. Module installations will now go to the virtual environment and the system site packages are visible too.

Install a Python package into a different directory using pip?

Use:

pip install --install-option="--prefix=$PREFIX_PATH" package_name

You might also want to use --ignore-installed to force all dependencies to be reinstalled using this new prefix. You can use --install-option to multiple times to add any of the options you can use with python setup.py install (--prefix is probably what you want, but there are a bunch more options you could use).

pip installing in global site-packages instead of virtualenv

Funny you brought this up, I just had the exact same problem. I solved it eventually, but I'm still unsure as to what caused it.

Try checking your bin/pip and bin/activate scripts. In bin/pip, look at the shebang. Is it correct? If not, correct it. Then on line ~42 in your bin/activate, check to see if your virtualenv path is right. It'll look something like this

VIRTUAL_ENV="/Users/me/path/to/virtual/environment"

If it's wrong, correct it, deactivate, then . bin/activate, and if our mutual problem had the same cause, it should work. If it still doesn't, you're on the right track, anyway. I went through the same problem solving routine as you did, which piping over and over, following the stack trace, etc.

Make absolutely sure that

/Users/kristof/VirtualEnvs/testpy3/bin/pip3

is what you want, and not referring to another similarly-named test project (I had that problem, and have no idea how it started. My suspicion is running multiple virtualenvs at the same time).

If none of this works, a temporary solution may be to, as Joe Holloway said,

Just run the virtualenv's pip with its full path (i.e. don't rely on searching the executable path) and you don't even need to activate the environment. It will do the right thing.

Perhaps not ideal, but it ought to work in a pinch.
