So I have python 2.7
have pip installed
pip is upgraded
cant install anything i get all kinds of errors and have tried all kinds of solutions.
why do i have to type: C:\Users\kingj>python -m pip install
instead of pip install without getting: C:\Users\kingj>pip install
'pip' is not recognized as an internal or external command,
operable program or batch file.
everyone else seems to just type pip install etc... i have to do python -m pip install
then when i do do it like that i get this:C:\Users\kingj>python -m pip install django-json
Collecting django-json
Could not fetch URL https://pypi.python.org/simple/django-json/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661) - skipping
Could not find a version that satisfies the requirement django-json (from versions: )
No matching distribution found for django-json
even though i have tried multiple packages by name and i get only that message?!
Sounds like your PATH variable isn't pointing to pip correctly. I'm not sure what the correct directory is in Windows as I'm a mac user. But i would start by looking there. Also, it may be worth uninstalling and reinstalling Python. I know there is a checkbox for updating your PATH variable when you do a fresh install of Python. Also, the newest versions of Python ship with pip correctly installed for you. If that is unsuccessful, check here: How do I install pip on Windows?

Originally, my app crashed with error ERROR: Failed building wheel for pycairo (in the picture)
Failed to build pycairo
I tried to fix it by running several commands
sudo apt install libcairo2-dev
sudo apt install cloud-init
Gave the same error. No fix.
then I tried uninstalling the requirements.txt and reinstalled
pip uninstall -r requirements.txt
pip install -r requirements.txt
Did not solve the issue.
then I tried the below command, but I still got the same error "Failed building wheel for pycairo":
pip3 install --upgrade pip (from this thread: ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly
then I tried this command:
pip install --upgrade pip setuptools wheel
and I got this error in the picture: "Invalid version: '0.23ubuntu1'"
Invalid version: '0.23ubuntu1'
I tried to also delete this package but it's showing that package not found:
command I used: sudo apt-get remove distro-info
Error:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'distro-info' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 283 not upgraded.
I searched for solutions but did not find any regarding the error "Invalid version: '0.23ubuntu1'". Now, when I run "flask run", I get error: -bash: /home/ktai/.local/bin/flask: No such file or directory
Would appreciate any help!
I tried several command lines but nothing worked
I learned from this answer that there is a "bug" with versions of setuptools causing this specific Invalid version: '0.23ubuntu1' error.
Despite seeing errors with all sorts of pip commands including pip install, I was surprised to see that this downgrade command (from the answer linked) appears to resolve the issue:
pip install --upgrade --user setuptools==58.3.0
Are you using ubuntu 20.04 by chance?
I had a similar issue but it had to do nothing with pycairo so the situation might be different for you.
The existence of distro-info (with a version not compliant to PEP-440) among my Python packages was leading to the error message from your post's title whenever i tried to install another package.
For me, this one helped: (so you were close with the apt-get remove...)
python3 -m pip uninstall -y distro-info
In my case, it seems like it didnt break anything important so i will keep it like this.
But there is no guarantee the same works for you as well. Also, you might get it back the next time you install packages from your requirements.txt file.
If I understood this thread correctly, there might be updates with a compliant version of this package depending on which Ubuntu version you are using.
This error arises from PEP 440 (Python Enhancement Proposal #440), which enforces conventions for naming of Python packages, and this error seems to really only happen on Debian-based distros like Ubuntu. For example, I have been trying to install a package via pip and get an error:
pkg_resources.extern.packaging.version.InvalidVersion: Invalid version: '1.1build1' (package: distro-info)
So it's telling us that 1.1build1 is an invalid version name per PEP 440, and it's probably getting the distro-info package from, in my case, Ubuntu (came preinstalled).
I can get around this by using a Python virtual environment and not allowing it to use system-site-packages, sometimes called "global packages".
The solution is to remove the offending package and reinstall a version of it that meets PEP 440 requirements (e.g. following the "0.0.0" convention. "1.2.0" for example is fine, "1.2build3" is not).
pip uninstall -y distro-info
pip install distro-info==1.0
Additionally, within PyCharm, I can navigate to the Python Interpreter settings, choose the interpreter I am using from the Python Interpreter dropdown, and confirm that the version of distro-info it's trying to use is 1.1build1. To "upgrade" this to 1.0, I can double-click on the "1.0" under the "Latest Version" column and select "Install Package" from the modal that pops up.
If this or the above command to remove distro-info isn't working, you can use this same window to remove distro-info and then simply run pip install distro-info==1.0.
Thank you for all the answers. To answer my own question, I was finally able to fix the issue by updating all the required packages.
Now there are no updates needed, and the app works again.
0 updates can be applied immediately.
The list of available updates is more than a week old.
To check for new updates run: sudo apt update
I'm trying to install a python module, 'pyAudioProcessing' (https://github.com/jsingh811/pyAudioProcessing) on my Linux Mint distribution, and one of the items in requirements.txt is causing issues: python-magic-bin==0.4.14. When I run pip3 install -e pyAudioInstaller, I get an error:
ERROR: Could not find a version that satisfies the requirement python-magic-bin==0.4.14 (from pyAudioProcessing==1.1.5) (from versions: none)
ERROR: No matching distribution found for python-magic-bin==0.4.14 (from pyAudioProcessing==1.1.5)
The same error appears if I try to manually install the module using pip3 install python-magic-bin. The module installs without issues on my windows machine.
pypi.org lets me download files for it manually, however only Windows and MacOS .whl files are available. I tried simply removing the requirement from the list, but that resulted in a large number of other errors to appear, so I assume the module is legitimately required.
Thee is another module called python-magic-debian-bin that I can download. Is there a simple way to convince pyAudioInstaller to use this other module instead of the original? Like can I somehow rename python-magic-debian-bin to python-magic-bin and hope it works out?
python-magic-bin 0.4.14 provides wheels for OSX, w32 and w64, but not for Linux. And there is no source code at PyPI.
You need to install it from github:
pip install git+https://github.com/julian-r/python-magic.git
As for pyAudioProcessing I can see 2 ways to install it:
Clone the repository and edit requirements/requirements.txt, replace python-magic-bin==0.4.14 with pip install git+https://github.com/julian-r/python-magic.git#egg=python-magic;
Install requirements manually and then install pyAudioProcessing without dependencies:
pip install --no-deps pyAudioProcessing
or
pip install --no-deps git+https://github.com/jsingh811/pyAudioProcessing.git
The library has updated the requirements very recently for it to work on Linux.
pip install -U pyAudioProcessing
Should get it all set up for you.
Alternatively, https://github.com/jsingh811/pyAudioProcessing the readme describes other getting started methods as well.
As of late, I have been attempting to setup MySQLDB on Pycharm. I have Python 3.8.5 installed, have made sure the PATH is set, and everything seems to be working handily. After this, I ran the pip command.
python -m pip install mysqldb
and
python -m pip install mysqldb-python
But to no avail.
I tried to install it from Pycharm's interpreter page, but also no dice. I also attempted to install using a .whl file, but that has also turned out a failure. I've searched far and wide for the last few days, and I've found mention of this error, but none of the fixes I've seen have truly worked. The error I get is the same, regardless of which iteration I attempt to install. And of all the guides I see, I never see any mention of steps I've missed or things I should have done before attempting an installation aside from what I've done. The error is as follows.
ERROR: Could not find a version that satisfies the requirement MySQLdb (from versions: none)
DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated. pip 20.3 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean. You can find discussion regarding this at https://github.com/pypa/pip/issues/8333.
ERROR: Could not find a version that satisfies the requirement MySQLdb (from versions: none)
ERROR: No matching distribution found for MySQLdb
you can try installing the following,
pip install pymysql
pip install mysql-connector
pip install mysql-connector-python
or you can go to lfd.uci.edu/~gohlke/pythonlibs/#mysql-python and install the wheels.
It looks like you're using the wrong package to try to install mysqldb through pip. I tried it and got the same error you did this tells me that pip is looking for a package to download and install, but cannot find it.
Try this instead:
pip install MySQL-python
You can learn more about this package here:

Using python 2.7. Was working fine for months but all of a sudden i start getting this weird error when i try and do pip installs outside of or within a virtualenv. If i do something like this:
pip install pandas
I am told:
Could not fetch URL https://pypi.python.org/simple/pandas/: There was a problem confirming the ssl certificate: EOF occurred in violation of protocol (_ssl.c:590) - skipping
Could not find a version that satisfies the requirement pandas (from versions: )
No matching distribution found for pandas
This occurs for just about any pip library and it is infuriating. I tried updating my pip and it said it was up to date. I read somewhere i should try and update my virtualenv which I did with:
pip install --upgrade virtualenv
But it gave the same error. So enraging haha.
As a temporary fix, you could fetch the appropriate .whl for your system from
this link and install it using
pip install some-package.whl
Otherwise, you should check the top anwser from here which seems to have fixed the problem when having trouble with ssl.
Unfortunately I cannot install any modules on python 3.4 32 Bit using the pip command due to the following error.
How do I get around the problem. I have removed all other installations of python and have installed the 32 Bit version rather than the 64 Bit one?
Thanks
Edit 1:
At the moment I can't even upgrade pip
Edit 2
Unfortunately it still returns an error.
Try upgrading your pip with
python -m pip install -U pip
If this fails too, it has to be a network problem. See if you're properly connected to internet.
Seems like you might be using an old version of PIP which is facing SSL certification issues and is hence unable to connect. You can do a manual reinstall of pip using these commands.:
python -m pip uninstall pip setuptools
Then, download this script
Finally, run the script with:
python get-pip.py
