I had Python versions of 2.7 and 3.5. I wanted the install a newer version of Python which is python 3.8. I am using Ubuntu 16.04 and I can not just uninstall Python 3.5 due to the dependencies. So in order to run my scripts, I use python3.8 app.py. No problem so far. But when I want to install new packages via pip:
python3.8 -m pip install pylint
It throws an error:
AttributeError: module 'platform' has no attribute 'linux_distribution'
So far, I tried:
sudo update-alternatives --config python3
and chose python3.8 and run command by starting with python3 but no luck.
Then:
sudo ln -sf /usr/bin/python3.5 /usr/bin/python3
I also tried running the command by starting with python3 but it did not work either.
How can I fix it so that I can install new packages to my new version of Python?
It looks like at least on my Ubuntu 16.04, pip is shared for all Python versions in /usr/lib/python3/dist-packages/pip.
This is what I did to get it working again:
sudo apt remove python3-pip
sudo python3.8 -m easy_install pip
You might want to install the python 3.5 version of pip again with sudo python3.5 -m easy_install pip.
Python 3.8 removed some stuff. I solved my problems with pip (specifically pip install) by installing pip with curl.
What worked for me was downloading get-pip.py and run it with Python 3.8:
cd ~/Downloads
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3.8 get-pip.py
Source: https://pip.pypa.io/en/stable/installing/
The problem is that package.linux_distribution was deprecated starting with Python 3.5(?). and removed altogether for Python 3.8.
Use the distro package instead. This package only works on Linux however.
I ran into this problem after installing OpenCobolIDE on Linux Mint 20, having upgraded Python to the latest level. have submitted a code fix to the OpenCobolIDE author to review and test. I was able to get the IDE to start up and run with this fix.
Essentially the fix uses the distro package if available, otherwise it uses the old platform package. For example:
This code imports distro if available:
import platform
using_distro = False
try:
import distro
using_distro = True
except ImportError:
pass
Then you can test the value of using_distro to determine whether to get the linux distro type from package or distro, for example:
if using_distro:
linux_distro = distro.like()
else:
linux_distro = platform.linux_distribution()[0]
In my case, removing python-pip-whl package helped:
apt-get remove python-pip-whl
It removed also pip and virtualenv, so I had to install them again:
curl https://bootstrap.pypa.io/get-pip.py | python3
pip install virtualenv
Check if your wheels installation is old. I was getting this same error and fixed it with
python3.8 -m pip install --upgrade pip setuptools wheel
Pylint seems to work on python3.8
I recently had this error and it turns out that I had a package called platform at a folder on my path ahead of the standard library and so the interpreter imported that instead. Check your path to what it is that you're actually importing.
If you have this issue when running a docker-compose up command. The solutions above do not work. You should install docker ce (https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-20-04)
I'm trying desperately to install PyQt5 for python2.7 on my Mac running macOS Sierra. I've tried running:
brew install pyqt5
As well as downloading the source code and compiling myself. Can anybody provide me with some quick commands that I can copy/paste into terminal to install PyQt5 for python2.7?
This is a pretty good rundown of the problem, and a solution:

I suppose you don't see using python3 as an option. Even within a virtualenv? Developing new software using python2 may become increasingly frustrating (more and more problems like the one you're encountering).
sudo easy_install pip
sudo pip install virtualenv
brew install python3
virtualenv -p python3 venv
. venv/bin/activate
pip install pyqt5

I'm on Ubuntu and I have python2.7, (it came pre-installed) python3.4, (used before today) and python3.5, which I upgraded to today, installed in parallel. They all work fine on their own.
However, I want to use pip to install some packages, and I can't figure out how to do this for my 3.5 installation because pip installs for 2.7 and pip3 installs python 3.4 packages.
For instance, I have asyncio installed on 3.4, but I can't import it from 3.5. When I do pip3 install aysncio, it tells me the requirement is already satisfied.
I'm a bit of a newbie, but I did some snooping around install directories and couldn't find anything and I've googled to no avail.
I suppose you can run pip through Python until this is sorted out. (https://docs.python.org/dev/installing/)
A quick googling seems to indicate that this is indeed a bug. Try this and report back:
python3.4 -m pip --version
python3.5 -m pip --version
If they report different versions then I guess you're good to go. Just run python3.5 -m pip install package instead of pip3 install package to install 3.5 packages.
Another way would be to setup a virtual environment:
$ python3.4 -m venv envdir
$ source envdir/bin/activate
$ pip --version
Obviously, this won't install the packages globally and you'll have to source venv/bin/activate every time you wan to make use of it.
I am attempting to install a package for python3.4 on Mac OSX 10.9.4. As you know, python ships with OSX, so when I installed python3.4 I was happy to find that it came with its own version of pip, that would install packages to it (installing pip on a mac with multiple versions of python will cause it to install on the system's python2.7.)
I had previously tried installing this package (https://pypi.python.org/pypi/chrome/0.0.1) with my first installation of pip (the one tied to python2.7) and found that it successfully installed on that version, but not on any others.
I ran an install with the new pip keyword for python3.4 (which when called by itself spits out the help page so i know it works) and it told me that the package was already installed and to try updating. The update revealed that I already had the most recent version. so I tried uninstalling it from just the python3.4 and reinstalling to no avail, and got the same results when uninstalling pip from python2.7 and reinstalling only on version 3.4.
I know that's a bit hard to follow but hopefully that makes sense.
I also reviewed the content here with no success.
RESOLVED:
while python did have a directory named the same as a directory it uses with packages, this was not the correct directory, for me it was in a subdirectory of library. while documentation said that referencing pip2 would cause the package to install on python3.4, this was false. however, referencing pip3.4 worked for me.
My suggestion is that you start using virtualenv.
Assuming you have 3.4 installed, then you should also have pyvenv. As for pip and 3.4, it should already be installed.
Using for example version 3.4 create your own virtual environment and activate it:
$ mkdir ~/venv
$ pyvenv-3.4 ~/venv/py34
$ source ~/venv/py34/bin/activate
$ deactive # does what is says...
$ source ~/venv/py34/bin/activate
$ pip install ... # whatever package you need
With version 2.7 first install virtualenv and then create your own virtual environment and activate it. Make sure that setuptools and pip are updated:
$ virtualenv-2.7 ~/venv/venv27
$ . ~/venv/venv27/bin/activate
$ pip install -U setuptools
$ pip install -U pip
$ pip install ... # whatever package you need
On Ubuntu 10.04 by default Python 2.6 is installed, then I have installed Python 2.7. How can I use pip install to install packages for Python 2.7.
For example:
pip install beautifulsoup4
by default installs BeautifulSoup for Python 2.6
When I do:
import bs4
in Python 2.6 it works, but in Python 2.7 it says:
No module named bs4
Alternatively, since pip itself is written in python, you can just call it with the python version you want to install the package for:
python2.7 -m pip install foo
Use a version of pip installed against the Python instance you want to install new packages to.
In many distributions, there may be separate python2.6-pip and python2.7-pip packages, invoked with binary names such as pip-2.6 and pip-2.7. If pip is not packaged in your distribution for the desired target, you might look for a setuptools or easyinstall package, or use virtualenv (which will always include pip in a generated environment).
pip's website includes installation instructions, if you can't find anything within your distribution.
You can execute pip module for a specific python version using the corresponding python:
Python 2.6:
python2.6 -m pip install beautifulsoup4
Python 2.7
python2.7 -m pip install beautifulsoup4
In Windows, you can execute the pip module by mentioning the python version ( You need to ensure that the launcher is on your path )
py -2 -m pip install pyfora
You can use this syntax
python_version -m pip install your_package
For example. If you're running python3.5, you named it as "python3", and want to install numpy package
python3 -m pip install numpy
Have tried this on a Windows machine and it works
If you wanna install opencv for python version 3.7, heres how you do it!
py -3.7 -m pip install opencv-python
Alternatively, if you want to install specific version of the package with the specific version of python, this is the way
sudo python2.7 -m pip install pyudev=0.16
if the "=" doesnt work, use ==
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev=0.16
Invalid requirement: 'pyudev=0.16'
= is not a valid operator. Did you mean == ?
x#ubuntuserv:~$ sudo python2.7 -m pip install pyudev==0.16
works fine
If you have both 2.7 and 3.x versions of python installed, then just rename the python exe file of python 3.x version to something like - "python.exe" to "python3.exe". Now you can use pip for both versions individually. If you normally type "pip install " it will consider the 2.7 version by default. If you want to install it on the 3.x version you need to call the command as "python3 -m pip install ".
Python 2
sudo pip2 install johnbonjovi
Python 3
sudo pip3 install johnbonjovi
For Python 3
sudo apt-get install python3-pip
sudo pip3 install beautifulsoup4
For Python 2
sudo apt-get install python2-pip
sudo pip2 install beautifulsoup4
On Debian/Ubuntu, pip is the command to use when installing packages
for Python 2, while pip3 is the command to use when installing
packages for Python 3.
for python2 use:
py -2 -m pip install beautifulsoup4
I faced a similar problem with another package called Twisted. I wanted to install it for Python 2.7, but it only got installed for Python 2.6 (system's default version).
Making a simple change worked for me.
When adding Python 2.7's path to your $PATH variable, append it to the front like this: PATH=/usr/local/bin:$PATH, so that the system uses that version.
If you face more problems, you can follow this blog post which helped me - https://github.com/h2oai/h2o-2/wiki/installing-python-2.7-on-centos-6.3.-follow-this-sequence-exactly-for-centos-machine-only
As with any other python script, you may specify the python installation you'd like to run it with. You may put this in your shell profile to save the alias. The $1 refers to the first argument you pass to the script.
# PYTHON3 PIP INSTALL V2
alias pip_install3="python3 -m $(which pip) install $1"
I'm using Ubuntu 22.04, which comes with python 3.10.4.
Some packages do not have recent pip packages, so I needed install from an older pip. This sequence worked for me.
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.9
sudo apt install python3.9-distutils
python3.9 -m pip install onnxruntime-gpu
Folder location: /usr/local/lib/python3.8
Package: python3.8 -m pip install <package_name>
I had Python 2.7 installed via chocolatey on Windows and found pip2.7.exe in C:\tools\python2\Scripts.
Using this executable instead of the pip command installed the correct module for me (requests for Python 2.7).
I think the best practice here is not to use the system python or install any system python package (no apt install). That is just the way to trouble.
Instead, build the required Python version from source, get it installed in /usr/local/... . Then use pip to install packages for that. It is really not that hard to build Python from source on Ubuntu.
sudo apt install build-essential
download the source from https://www.python.org/downloads/source/
unpack the file downloaded: tar xf <filename>
cd <directory> - change into the directory created.
./configure
make
sudo make install
Then check /usr/local/bin for a pip script tied to that version. Use that to pip install whatever you need. Also find the particular executable for the python version in that directory. You might have to shuffle things a bit if you get lots of versions.
Again, do not mess with system python.
