Question:
I’m currently trying to install Flask for testing a simple web page.
Unfortunately i got the following message:
Command 'virtualenv' not found, but can be installed with:
sudo apt install python3-virtualenv
When i do it, i got :
Unable to locate package python3-virtualenv
I check my python version and I’m on Python 3.10.4
Whent i try sudo apt-get update i got:
W: Some index files failed to download. They have been ignored, or old ones used instead.
Whent i try sudo apt-get upgrade i got:
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
And when i try sudo apt-get install python3-venv i got :
E: Package 'python3-venv' has no installation candidate
Answers:
sudo apt install python3-virtualenv
works perfectly fine with me.
Alternatively you can install it using pip
pip3 install virtualenv
After completion you can check for which virtualenv
to get the path of the location where it has been installed.
It seems there is an error with your ubuntu, You can use this site and fix it and then install the virtual environment : https://www.tecmint.com/some-index-files-failed-to-download.
Had this problem after upgrading to Ubuntu 20.4 and all my problems stemmed from a very old version of Pip that was solved by this lovely command:
curl -sS https://bootstrap.pypa.io/get-pip.py | python3
More information and some alternatives here: pip3 install not working – No module named 'pip._vendor.pkg_resources'
