I have installed python 3.9 in Ubuntu, because it comes with python 3.8 which is an older version.
I changed the command for terminal alias python 3 = python 3.9, but when I installed pip, it installed for python 3.8 and after that when I am using pip install to install python packages, it installs for python 3.8. How can I fix it?
try with pip3 install
This kind of issue even happened to my case when I was working with the python modules recently on my project. Try this out it worked for me.
Due to variations in the installation process of python, pip often requires different ways to access for different people. A few examples that may help you include pip3 install, py pip install py -3 pip install or python3 pip install. Usually one of these works for me.

Today I faced a problem regarding pip3 in Ubuntu. Ubuntu comes with python 3.8 but I wanted to use latest versions of python, like 3.9 or maybe 3.10. So I installed it using 'ppa:deadsnakes' repository and also installed pip. But the problem is I want to use pip in python 3.9 instead of version 3.8. So I changed the default python version to 3.9 and everything crashed.
So reverted to python 3.8. Whenever I install some package it gets installed using python 3.8.
Help me, how can I use python 3.9 pip and install packages in python 3.9 without changing the default version.
Any help is appreciated.
--> Thing I want is that when I want to install python package using
pip3 install <package_name> it must install in python3.9 and not in python3.8
You don't need to install pip separately
You should be able to refer to it as such
python3.9 -m pip install
Hello everyone I fixed my issue.
The problem is we cannot override default python version in Ubuntu as so many things depend on it.
So I just made an alias as : alias pip3='python3.9 -m pip' and alias for python : alias python3='/usr/bin/python3.9'
If anyone face this issue please do what I specify and you will be good to go.
Now all my packages are being installed in python3.9.
Currently all python3 versions are using the same pip version which can be installed by:
sudo apt-get install python3-pip
The easiest way to work with a specific python version is creating a virtualenv and working under it. When working with a virtualenv you can use pip freely without worrying about which python version it belongs.
you can use pip for python3.9 by pip3.9 install <package-name>
I only installed Python 3.8.1 on my Windows 10, from some instructions I started to use pip3 and installed all the requirements with pip3 but I was hit with numerous problems, especially the packages I just installed can't get imported by python error. Then I did this pip3 --version and pip --version, the results are different. Then I did pip --list and pip3 --list, the results are different too, of course, so I did all the requirements in pip, and that seems to fix my problem.
So now I have this question, why is there a pip and then a pip3 on the same Python 3.8.1?
where pip and where pip3 both return the same folder, C:\Python38\Scripts\pip3.exe
Binaries like python and pip point to the default version of Python which was often 2.x, and pip3 and python3 point to the latest installed version of Python 3.x. This was necessary because a lot of software was written for Python 2 and not updated to work with py3. Now that python 2 has reached its end of life, this should hopefully go away in the future.
I have two versions of python installed. 2.7 and 3.7.4. I want to install Pygame to 3.7 but am failing.
I've tried multiple tutorials and methods but no luck. Python 2.7 has all the files but 3.7 has only exes but still works perfectly fine.
If you are using pip, you could always try specifying the exact Python versions to install for:
$ python2.7 -m pip install pygame
$ python3.7 -m pip install pypgame
I am using RedHat Linux.
Python 2.6 is already installed in usr/src/bin. When I install Python 2.7, it gets installed in usr/local/src/bin.
Further, I need to install sklearn. When I try installing sklearn using pip, it refers to Python2.6 and not Python2.7.
You can run python -m pip to see if pip is using the right version of python
I think you can probably specify the location with usr/local/src/bin pip install If you're sure that's where python 2.7 is installed. If pip is not using python 2.7 you should reinstall pip in the correct version.
There is another question which could help solve yours:
Pip Install not installing into correct directory?
I have a server with CentOS installed on it. Python 2.6.6 was installed on it. I installed python 3.4.2 and 2.7.8. Now when i use command like :
pip install virtualenvwrapper
it's stop with error and error is for using different packages. How can i remove other packages and have just python 3.4.2?
Sorry for my terrible English.
If you want to uninstall a package through pip, you can try
pip uninstall <package>
