I am trying to install a package which uses PEP 517. The newest version of Pip won’t allow me to install due to an error involving wheel building for 517.
In the past, I’ve solved this issue by downgrading Pip, installing the package and Upgrading Pip back to the latest version. However, after I downgrade pip in my virtualenv, if I try to run ‘Pip install black’ I get the No module named ‘pip._internal.cli.main’ error.
How can I solve this?

The easiest solution to deal with the error
"Could not build wheels for ____ which use PEP 517 and cannot be installed directly"
is the following:
sudo pip3 install _____ --no-binary :all:
Where ____ is obviously the name of the library you want to install.

This solution from this link helped me:
pip install --upgrade pip setuptools wheel

Sometimes this can be due to a cache issue and the no-binary flag won’t work. In which case try pip install <insert package names> --no-cache-dir.
This seems to be a frequent issue when installing packages with python. First, check to ensure you have activated the virtualenv you think you’re supposed to be in, then check to see if you have wheels pkg (pip install wheel if not). If those fail then the –no-cache-dir or –no-binary flags come into play. Reading the pypi documentation on each package could help as well. Best of luck!

Posting an answer as reference for future searchers here.
I tried installing Pillow and got this error. Tried many different approaches, none of them worked.
Then i downgraded Python (From 3.9) to 3.8 and just tried installing by pip again, then it worked.
If it fails for you, try downgrading Python, and it may work.

When I ran into this error, the problem was that the package I was pulling had its metadata configured incorrectly, which caused building the wheels to fail.
To find that error I ran, pip --verbose install <my_package> Which let me see what about the wheel build was failing, and fix it upstream.

try this:
pip3 install –upgrade pip

On OSX setting SYSTEM_VERSION_COMPAT=1 in my environment prior to running pip solved it:
export SYSTEM_VERSION_COMPAT=1

I have also encountered the same issue when uninstalling and reinstalling miniconda.
I have no idea why, but in my registry key ComputerHKEY_CURRENT_USERSOFTWAREMicrosoftCommand Processor AutoRun has been set to if exist. I deleted the value then it worked fine just as before.

I am building a library that follows standard practices when it comes to development, testing and release (using tox and pytest, setup.cfg, etc). Sometime this morning, I suddenly started getting the following error when I attempt to run my tests and I am stumped as to the root cause.
Building wheels for collected packages: python-step-series

I know it has something to do with git tagging and the fact that my working tree is dirty, but how to fix this is beyond me. Until this morning, I never had an issue. Creating a new tag every time I want to run my tests (using tox) seems to band-aid this–until my working tree becomes dirty again. Regardless, this band-aid isn’t efficient nor proper.
I’m using tox-conda instead of virtualenv, but each environment is reporting Pip version: 21.2.4 (python 3.7,3.8, 3.9. 3.10)
Has anyone else encountered or have knowledge of this issue and how to fix it?

I am on the latest Poetry version.

I have searched the issues of this repo and believe that this is not a duplicate.

If an exception occurs when executing a command, I executed it again in debug mode (

Issue
A dependency uses MarkupSafe and our project must support python ^3.6.2. Since I updated to poetry 1.2.0, I can not use the python 3.6 environment anymore.
Installing MarkupSafe manually works, when I disable pep 517:
> poetry run python -m pip install --no-use-pep517 markupSafe==2.0.1
However, there is no option to disable pep 517 in poetry.
Is there any other way to install such packages?

While trying to install jupyter notebook in Mac OS with PIP (source)
You could get error message like:
ERROR: Could not build wheels for argon2-cffi which use PEP 517 and cannot be installed directly
In this article I have added the series of steps I tried and it’s possible the issue for you could be fixed with just of them (based on what the underlying issue is).
Solutions
[1] Try to install Argon2-CFFI separately
Argon2-CFFI is a secure password hashing algorithm. Try to install it separately:
If it works try to install jupyter notebook again. Most likely this will fail with the same error.
[2] If it doesn’t work, make sure your PIP is updated to latest version
pip install --upgrade pip --user
The installation worked for me after this step. But since I didn’t follow the steps in this order I found other solutions that worked for some other folks. Adding it here, in case it comes in handy.
[3] Install xcode command line tools
This command is used to install the command line developer tools. This should ideally open a popup and after the installation is complete, try running the notebook installation again.
[3.1] Error while xcode-select –install, reinstall command line tools
xcode-select --install could sometime fail with following error
$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
Based on the SO answer for How to update Xcode from command line – the easiest way to do this would be to remove the old version of the tools and reinstall the new one.
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
A popup will open and it will take a bit of time to install the command line tools.
Figure: Popup while the command line tools are being reinstalled.
[4] Still failing with the same error
If you are still getting following error:
ERROR: Could not build wheels for argon2-cffi which use PEP 517 and cannot be installed directly
Per this you could try to install p5py and PEP517 directly.
pip install p5py
pip install PEP517
If this fails with
ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/3.8'
Consider using the `--user` option or check the permissions.
Follow the advice:
pip install p5py --user
pip install PEP517 --user
If it works, run jupyter notebook to verify
It should run without error:

I had the same problem and i did this,
pip install --upgrade pip setuptools wheel
then install opencv again,
pip install opencv-python
this worked for me
Solution 2:[2]
Yes .. Finally found a work around.
Follow this https://github.com/mdegans/nano_build_opencv and build from source and finally gets installed.
PS: It may take a bit long for building, for me it took 10 Hrs :P.

If after
pip install --upgrade pip setuptools wheel
you still have the same error,
You can try to specify the older version of OpenCV to install.
Ex.
pip3 install opencv-python==3.4.13.47
Solution 4:[4]
I had a similar problem and what solved it for me was not to use python:3-alpine but python:3.8-slim. E.g.:
FROM python:3.8-slim
WORKDIR /usr/src/app
RUN apt update
RUN apt -y install build-essential libwrap0-dev libssl-dev libc-ares-dev uuid-dev xsltproc
RUN apt-get update -qq
&& apt-get install --no-install-recommends --yes
build-essential
gcc
python3-dev
mosquitto
mosquitto-clients
RUN pip3 install --upgrade pip setuptools wheel
RUN python3 -m pip install --no-cache-dir
numpy scipy matplotlib scikit-build opencv-contrib-python-headless
influxdb paho-mqtt configparser Pillow
qrcode
worked finally for me.
Solution 5:[5]
please check your python specifications:
- opencv -> python[
version='
>=2.7,<2.8.0a0
>=3.5,<3.6.0a0
>=3.6,<3.7.0a0
>=3.7,<3.8.0a0']
Solution 6:[6]
I handled it by reinstalling python3 from scratch in my MacBook:
brew reinstall [email protected]
I also reinstalled numpy and matplotlib packages experimentally.
pip3 install numpy
pip3 install matplotlib
pip3 install opencv-contrib-python
The versions:
macOS Mojave 10.14.5
Python 3.9.7
OpenCV 4.5.3
OpenCV’s version is 4.5.3 by this way:
import cv2
print(cv2.__version__)
But by “pip list”, it shows “opencv-contrib-python 3.4.9.31”.
Solution 7:[7]
if you are trying to install opencv in your raspberrypi 3B, Use following steps:
- sudo raspi-config
- advanced — expand filesystem
- reboot your pi
Open your raspi terminal and do following stuff:
- use command: sudo apt-get update
- use command: sudo apt-get upgrade
- check your python version and upgarde it to latest one
- install pip and upgrade pip
- use command: mkdir project
- use command: cd project
- create virtual environment
- activate virtual environment
- install dependencies ,can get dependencies from https://singleboardbytes.com/647/install-opencv-raspberry-pi-4.htm
- if error in installing libdhf5-dev
- use command: sudo apt-get install python3-h5py and reinstall libdhf5-dev
- use command: pip install scikit-build
- use command: pip install cython
- before installing opencv ,make sure you are in virtual environment or
activate environment - use command: pip install –no-cache-dir opencv-contrib-python==4.5.3.56
- Remember to use mentioned version…
Thank You…
