I installed several packages (among them patsy and statsmodels) with pip 1.3.1 in kubuntu 13.04. They were put into /usr/local/lib, instead of /usr/lib. When using pip freeze or pip list, these packages appear fine, and are usable in python. However, when I use pip uninstall I get "Can't uninstall 'statsmodels'. No files were found to uninstall." The structure of install packages in /usr/local/lib/python2.7/dist-packages seem correct, and installed-files.txt has everything listed. How do I make pip see these files and uninstall them?
I do not really have a solution for the pip path lookup, but deleting /usr/local/lib/python2.7/dist-packages/_PACKAGE_NAME did the trick for me. At the very least it allowed me to install anew.

I am using python 3.6.0 within a venv. I would like to "pip install" matplotlib==2.0.0, however when I do this, pip seems to automatically grab the newest versions of all other required supporting packages for matplotlib. i.e. cycler 0.11.0, pyparsing==3.0.7, etc. These latest supporting package versions do not seem to work with the older version of matplotlib and it throws errors when attempting to import matplotlib.
How do I install matplotlib without pip attempting to install all its supporting packages automatically?
My current temporary solution is to go back and manually install each package before installing matplotlib but I'm sure I will run into this issue again so would like to find a better solution.
Pip has a built-in feature:
pip install matplotlib --no-dependencies
To exclude specific, you can put it in requirements file and pass it:
pip install --no-deps -r requirements.txt
I uploaded my package to testpypi, and installed it via:
pip install -i https://test.pypi.org/simple/ myporj==0.1.6
However it refuse to install it by saying:
Requirement already satisfied: myproj==0.1.6 in ./projs/myproj (0.1.6)
I guess I may add the project in editable mode:
pip install --editable .
However, I know want to disable it. I tried:
python setup.py develop --uninstall
But it has no effect.
It may be worth creating a separate env (Virtual Environments) for the installation.
Here are some articles on this subject:
https://docs.python.org/3/tutorial/venv.html
https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment
Or does it need to be installed in the same place?
You can try to find your package pip search myporj or pip list for show all packages.
And uninstall it later pip uninstall myporj (it may require the right of sudo in linux) then install again.
Maybe you may need --no-cache-dir option to ignore the cache during installation. Here is more details: https://pip.pypa.io/en/stable/reference/pip_install/#caching
In the server that work in (as do many other people) the "global" python has a certain version of a package, say 1.0.0.
I recently used pip to upgrade that to 1.0.2 locally for my user with the pip install --user package==1.0.2, which worked. However, now I want to uninstall my locally installed version and remain with the global one.
I've tried pip uninstall --user package==1.0.2, pip uninstall --user package, and a few other options but nothing seems to work. I always get this error:
Usage:
pip <command> [options]
no such option: --user
I also tried pip install --user package=1.0.0 but now I have both versions installed locally and python uses the most recent.
How can I do what I want?
Apparently this cannot be done with pip directly. I ended up solving it just by removing the package from ~/.local/lib/python3.5/site-packages/. A bit more manual than I was hoping I'd have to do.
The --user option for pip seems to have been removed but is still an option with setuptools.
So if you want to use the --user function what you can do is use pip download which will download the .whl file. You then need to extract the file using wheel unpack. I then ran python setup.py install --user (worked for numpy) and it installed the package to my home directory under .local.
I followed the documentation here.
I recently updated from Python 3.5 to Python 3.6 and am trying to use packages that I had previously downloaded, but they are not working for the updated version of Python. When I try to use pip, I use the command "pip install selenium" and get the message "Requirement already satisfied: selenium in /Users/Jeff/anaconda/lib/python3.5/site-packages" How do I add packages to the new version of Python?
First, make sure that your packages do have compatibility with the version of Python you're looking to use.
Next, run pip freeze > requirements.txt in the base directory of your Python project. This puts everything in a readable file to re-install from. If you know of any packages that require a certain version that you'll want to re-install, put package==x.x.x (where package is the package name and x.x.x is the version number) in the list of packages to make sure it downloads the correct version.
Run pip uninstall -r requirements.txt -y to uninstall all packages. Afterwards, run pip install -r requirements.txt.
This allows you to keep packages at the correct version for the ones you assign a version number in requirements.txt, while upgrading all others.
I currently have installed pip 8.1.2.
So I want to upgrade it to the latest version (9.0.1) and I execute:
sudo pip install --upgrade pip
Collecting pip
Downloading pip-9.0.1-py2.py3-none-any.whl (1.3MB)
100% |████████████████████████████████| 1.3MB 846kB/s
Installing collected packages: pip
Found existing installation: pip 8.1.2
Not uninstalling pip at /usr/lib/python2.7/dist-packages, outside environment /usr
Successfully installed pip-8.1.2
You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
It seems that it correctly downloads 9.0.1 but then it refuses to uninstall the existing installation (8.1.2)
And then at the end it suggests me to upgrade using the same exact instruction I already provided!
Am I doing anything wrong?
The Ubuntu pip version has been patched to prevent self-upgrades (all installation into system-managed files are prevented, the patch is named hands-off-system-packages.patch). You are supposed to use the Ubuntu packaging system to upgrade instead. The feedback provided could be improved certainly.
As there is no Ubunutu package of pip 9.0.1 available yet for your Ubuntu version, you can't actually upgrade to a newer version this way (there is a version for Zesty however).
A (ugly) work-around is to use easy_install instead:
sudo easy_install -U pip
This works because easy_install has not been booby-trapped to prevent the upgrade. However, this'll replace system managed files with the newer pip version. If your package manager were to re-install the python-pip package, it'll happily overwrite those files and you could in theory end up with a broken installation. Also, easy_install adds more files than the package would, and those extra files could cause issues later down the line, especially when you upgrade python-pip later when a new version is packaged.
If you were to use a virtualenv, you are free to upgrade pip inside that, which works just fine.
If above are not working, please try this it works(I had similar situations and this works):
download get-pip.py:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Run the downloaded file: python get-pip.py
Above uninstalls the old version and install the latest ones.
Reference Link: https://pip.pypa.io/en/stable/installing/#installing-with-get-pip-py
Had a similar issue with pip not wishing to upgrade, though I'm not keen on replacing the package manager's version and as I'm always adding the --user option on installations via pip I figured "what's the harm?" in doing the same with pip on itself.
pip install --user --upgrade pip
It'll only work for one user but for some use cases that is just peachy.
