I want to install a module with pip, in my case pydub.
However pip install pydub installs pydub in /home/<user>/.local/lib/python2.7/
So when I run my script
python3 myScript.py
it tells me
ModuleNotFoundError: No module named 'pydub'
How do I get pip to install pydub for 3.x rather than 2.7?
Use pip3 install xxx, or better yet, python3 -m pip install xxx. The problem here is that by default pip is aliased to python2's installation.

I tried to install PyMuPDF on Python 3.9 when first I installed by pip install PymuPDF and re-checked by pip list like this"
But when I imported PyMuPDF:
ModuleNotFoundError: No module named 'PyMuPDF'
Next, I tried to install PymuPDF from doc, it said I need install MuPDF first, and install with Wheel, I tried both:
pip install C:\Users\Admin\Desktop/PyMuPDF-1.19.6-cp310-cp310-win_amd64.whl and pip install PyMuPDF-1.19.6-cp310-cp310-win_amd64.whl but reviced error:
yMuPDF-1.19.6-cp310-cp310-win_amd64.whl is not a supported wheel on this platform.
What should i do to install PyMuPDF, thank you all.
PyMuPDF is available with a wheel under all Windows versions - you should have no problem at all.
But please follow this procedure:
Make sure your pip is the current one. This ensures that any changes in supported platform tags are known to pip.
Then install PyMuPDF.
So overall
py -3.10 -m pip install -U pip
py -3.10 -m pip install -U pymupdf
This should simply work!
In your script however you must do import fitz - this is the top-level name of the package.

I have installed both python3 and pip3 but when I use pip3 to install pyserial I get a no module error. The wrong directory is being used. How can I fix it please? volumio#pnbvolumio:~$ sudo python -m pip3 install pyserial /usr/bin/python3: No module named pip3 volumio#pnbvolumio:~$ pip3 --version pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)
Using pip with sudo is not a good idea.

Try to install pyserial using this command:
python3 -m pip install pyserial
You can also try to instal it for current user only:
python3 -m pip install pyserial --user
Also consider using virtual environmet to manage multiple environments and hassle free module managing.
I want to install fenics in Ubuntu 20.
First I made a python environment using:
sudo apt install python3-venv
Then inside the folder I want to make an environment I open a terminal and use:
python3 -m venv myproject
myproject is the name of the environment I made.
I then activate my environment:
source myproject/bin/activate
To install fenics for this particular environment while I activated the environment, I use:
pip install fenics
I verify the installation using pip list which returns:
Package Version
-------------- --------------
fenics 2019.1.0
fenics-dijitso 2019.1.0
fenics-ffc 2019.1.0.post0
fenics-fiat 2019.1.0
fenics-ufl 2019.1.0
mpmath 1.1.0
numpy 1.19.4
pip 20.0.2
pkg-resources 0.0.0
setuptools 44.0.0
sympy 1.7.1
I try to import fenics using:
python -c "import fenics"
But I get the error below stating there is not fenics module:
raceback (most recent call last):
File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'fenics'
What is the problem? Hopefully, after successful installation of fenics, I can install Spyder and other python packages and will be able to use fenics inside spyder.
Edit
I want to install fenics in a python virtual environment.
The issue here is that fenics is just a meta-package and it does not contain any library that you can use in your Python code.
Quoting from the README for the fenics project :
This package contains a single file, setup.py, that allows all of the FEniCS Python components to be installed from PyPI using pip:
pip3 install fenics
Actual use of the library is done via
import ffc
All different components are under this package. For example, fenics-fiat is available as ffc.fiatinterface.
Fenics library of python
If you have installed pip than you have to use pip install fenics. If you have installed pip3 than `pip3 install fenics
I have already installed both.
sudo apt update
sudo apt install python3-pip
Install pip for Python 2 with:
sudo apt install python-pip
After doing pip3 install fenics,write python3 -c import ffc to import it. If this works, it has been imported. It is called ffc, not fenics
After upgrading my pip to version 10 using pip3 install --upgrade pip and above I cannot I want to install/upgrade PyPi packages using pip3 install PyPiPackageName as I get the following error:
from pip import main
ImportError: cannot import name main
I wonder how I can install PyPi packages using pip when I'm using new versions of pip? I've seen some people use pyhton3 to do this but doing python3 -m pip install --upgrade pip gave me the following error and I cannot upgrade pip to higher versions:
/usr/bin/python3: No module named pip
Before doing python3 -m pip install --upgrade pip I do python3 -m pip install -U pip and I get the following error:
/usr/bin/python3: No module named pip
So I'm confused on what I need to do to be able to upgrade or install PyPi packages.
In addition to executing the following:
curl https://bootstrap.pypa.io/get-pip.py | python3.6
I also had to make sure python3 is using Python 3.6 otherwise Python 3.5 is used (which does not come with pip by default). So I did the following and things work fine now:
ln -s /usr/bin/python3.6 /usr/local/bin/python3
I'm trying to install packages for my python 3.5.0 versus my python 3.4.3
I can run both by typing either python3.4 or python3.5
I have pip2 and pip3. I also ran the script sudo easy_install3 pip, which made me be able to use pip3.4 But I am still having trouble installing modules for python3.5. pip3 just installs for python3.4
I am looking to install termcolor for python3.5 and I am having no success. Can anyone help?
I am on Windows, and you appear not to be, but maybe the following will help.
If pip is in your system's equivalent of python35/Lib/site-packages, then python3.5 -m pip should run pip so that it installs into the 3.5 site-packages.
If you do not have pip in the 3.5 site-packages, copy its directory, along with its dependencies (pip....dist-info/, setuptools/, setuptools....dist-info/, and easyinstall.py) from the 3.4 site_packages.
Or, if pip3 or even pip3.4 is in python35/Scripts, run it with its full path name so you are not running the 3.4 version.
