It looks like setuptools>=58 breaks support for use_2to3:
setuptools changelog for v58
So you should update setuptools to setuptools<58 or avoid using packages with use_2to3 in the setup parameters.
I was having the same problem, pip==19.3.1

I install setuptools==58It worked for me. pip install setuptools==58. The error coming from setuptools==69 that previously run on my device. and Finally saved me setuptools version 58 for this error.

This worked for me.
pip install --upgrade pip setuptools==57.5.0

"pip install setuptools==58" worked for me. The setuptools version was 59 when I upgraded ubuntu to 22.04 and its python 3.10. I started a clean virtual environment for an existings django project. It had just two packages:
`pip list
Package Version
pip 22.0.2
setuptools 59.6.0`
Then I downgrade the setuptools to 58 as pip install setuptools==58.0.0. After that the pip install -r requirements.txt has not such error above.

Upgrading MongoEngine to >= 0.20 would also fix the problem as Python2 support (hence use_2to3) was dropped in 0.20

I'm working on Windows 11 and these solutions didn't work. I installed pybluez2 instead. Your python version >= 3.9 on Windows.
pip install pybluez2

I can't download scipy for python on raspberry pi [duplicate]

I am trying to install the scipy library with python3 -m pip install --user --no-use-pep517 scipy but I am receiving the following error:
ERROR: Failed building wheel for scipy
Running setup.py clean for scipy
ERROR: Command errored out with exit status 1:

cwd: /tmp/pip-install-spokr6ic/scipy
I am using that code to install because pip3 install scipy is giving me this error:
ERROR: Failed building wheel for scipy
Failed to build scipy
ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly
How can I resolve this issue?
Python == 3.7.3
PS:The complete traceback is 414 lines. I don't know if I should include here.

Try this:
sudo apt update
sudo apt install -y python3-scipy

help me please

You must first install the Python version compatible with scipy.
I could not use pip to install scipy version 1.1 [ I think this version is no longer supported on pip] and used conda instead:
conda install -c anaconda scipy==1.1.0

if you are using pip make sure that, of python2 is installed. or else try with the python3
pip install scipy==1.1.0 for python
pip3 install scipy==1.1.0 for python3
it will install successfully
pip install scipy==1.1.0

Unable to install NLTK with Python 3.7

The NLTK docs say it supports Python 3.7. However, when I try to install it with:
virtualenv -p python3.7 .env
. .env/bin/activate
pip install nltk
I get the error:

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
The error message sounds like NLTK only supports Python < 3.4, but that doesn't make any sense. What am I doing wrong?

It is because the package format was not supported by the distutils, which indicates the package tools may be too old.
Upgrade pip in the virtual environment.
pip install -U pip
pip install -U setuptools
Retry to install nltk.
. .env/bin/activate
pip install nltk
If this still doesn't work. Provide log from pip install nltk -v.

First of all you have to upgrade your pip by using this command
python -m pip install –upgrade pip
First of all you have to navigate to the location of the pip folder
C:\Users\Admin>cd C:\Python\Scripts
Then run this command
pip3 install nltk
hope it will work!
