When I do
pip install Flask or
pip install click or
pretty much pip install <anything> returns the same error :
Could not find a version that satisfies the requirement Flask (from versions: ) No matching distribution found for Flask
Same error for any virtual environment I may have created.
I'm on Mac OS, using Python 3.4.
Upgrade pip:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
Latest version is 10+, check your version using pip --version

I'm using python3.8.6 and I need to upgrade to 3.9.x. After upgrade the python, myproject.py cannot find a module that already installed using pip3 install opencv-python.
when run python3 myproject.py occurs error that ModuleNotFoundError tensorflow, and tensorflow should be 2.5.x so I'm trying to install python 3.9.x.
pip --version shows pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
How can I change that (python3.8) to (python3.9)?
sorry for my bad English..
python -m pip install –upgrade pip.
If you type pip list it will show you every package installed and should say something like WARNING: You are using pip version 21.2.3; however, version 21.2.4 is available.
You should consider upgrading via this command:
c:\users\x\python.exe -m pip install --upgrade pip
Environment: Debian, Debian GNU/Linux, 10 (buster), amd64 built on 20210609, supports Shielded VM features.
Platform: Google cloud compute engine
Python version: Python 3.7.3
pip3 version: pip 18.1
command: pip3 install mediapipe
result:
Collecting mediapipe
Could not find a version that satisfies the requirement mediapipe (from versions: )
No matching distribution found for mediapipe
I have also tried to install it by downloading .whl file of it
command: pip3 install mediapipe-0.8.5-cp37-cp37m-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
respose:
mediapipe-0.8.5-cp37-cp37m-manylinux_2_17_x86_64.manylinux2014_x86_64.whl is not a supported wheel on this platform.
It seems that mediapipe has some Incompatibilities found with python > 3.7.0. There are issues with python 3.9+, or with python 32-bit (rather than 64)
My suggestion is to downgrade python version to 3.6 using conda. We will create a python environment with the suggested version 3.6:
$ sudo apt install wget
$ wget https://repo.anaconda.com/archive/Anaconda3-2021.05-Linux-x86_64.sh
$ chmod +x Anaconda3-2021.05-Linux-x86_64.sh
$ ./Anaconda3-2021.05-Linux-x86_64.sh
$ conda install python=3.6
$ conda create --name py36 python=3.6
$ conda activate py36
$ pip install mediapipe
There are multiples ways to solve this, but I have reproduced in your exactly same environment and it works.
You need to install 64-bit python. just uninstall the 32bit python and install
64-bit version of python from:
https://www.python.org/downloads/
Maker sure to check the "Add to PATH" checkbox during installation.
After installing, you can run pip command and mediapipe will be installed smoothly.
pip install mediapipe
I am trying to get the installation right with python 3, pip and pip3. I am working on a mac and by default. I have Python 2.7.10
python -V
Python 2.7.10
python3 -V
Python 3.5.1
What is the correct order of installation commands to install python3 pip and pip3 so that both pip and pip3 can be linked to python3?
This what I get when I try to see what versions I already have:
$ pip -V
-bash: /usr/local/bin/pip: No such file or directory
$ pip3 -V
pip 7.1.2 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (python 3.5)
I need to get this right so that I can install numpy afterward because now with what I have above this is what I get:
$ pip3 install numpy
Collecting numpy
Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy
I have Solved it. as #keithpjolley suggested. I installed anaconda, launched it, and I used the command:
conda install numpy
I let it solve the environment. It gave me an older version of numpy at first so I upgraded:
conda install numpy=1.13
Now everything is working with my code.
I have to install the module guizero for a piece of Python homework I've been given but it's not working.
This is all on Terminal on my Mac, version 10.7.5
People have said that I go to Library/Python but this is another problem. My MAC doesn't show me any folders named Python in Library. This is what the Library Folder looks like:
Library Folder
The command I'm using is
pip3 install --user guizero
and I get this error:
Could not find a version the satisfies the requirement guizero (from versions: )
No matching distribution found for guizero
Can anyone help with this?!
Try to update your pip version:
pip install --upgrade pip
Or pip install guizero version==0.2.1
Pip can't just magically invent what guizero is. You need to download guizero-0.2.1-py3-none-any.whl from https://pypi.python.org/pypi/guizero. Save it in your Library/Python/2.5/site-packages (replace 2.5 with your version) folder and then type pip install guizero-0.2.1-py3-none-any.whl in the terminal (typing guiz and tab twice should auto complete the file name for you)
EDIT
First install easy_install
curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python
Then install pip
sudo easy_install pip
You can now install any module using
pip install guizero
I've been searching the web for ways to solve this issue but nothing works.
I have a web server with CentOS 6.7 and I've successfully installed python 2.7.10 on it (it comes with version 2.6.6)
I followed up to step two in this site: https://cpaneltips.com/install-python-2-7-python-3-x-centos-cpanel/
I then installed virtualenv (using pip) and created another directory called "news"
Installed virtualenv and activated it so I have a python 2.7.10 environment. I ran "pip install scrapy"
But I have been getting this frustrating error:
Could not find a version that satisfies the requirement Twisted>=10.0.0 (from scrapy) (from versions: )
Some externally hosted files were ignored as access to them may be unreliable (use --allow-external Twisted to allow).
No matching distribution found for Twisted>=10.0.0 (from scrapy)
I then ran "pip install --allow-external scrapy scrapy"
still doesn't work... What am I missing?
wget https://pypi.python.org/packages/source/T/Twisted/Twisted14.0.0.tar.bz2#md5=9625c094e0a18da77faa4627b98c9815 --no-check-certificate
tar -vxjf Twisted-14.0.0.tar.bz2
cd Twisted-14.0.0
python setup.py install
pip install scrapy
It's clear you need twisted, you can firstly install twisted in your virtualenv:
pip install twisted
and then install scrapy:
pip install scrapy
This worked for me:
wget https://files.pythonhosted.org/packages/12/2a/e9e4fb2e6b2f7a75577e0614926819a472934b0b85f205ba5d5d2add54d0/Twisted-18.4.0.tar.bz2
tar -vxjf Twisted-18.4.0.tar.bz2
cd Twisted-18.4.0
python setup.py install
pip install scrapy
