I\'m installing several Python packages in Ubuntu 12.04 using the following requirements.txt
file:
numpy>=1.8.2,<2.0.0
matplotlib>=1.3.
If you facing this issue at the workplace. This might be the solution for you.
pip install -U <package_name> --user --proxy=<your proxy>
Below command worked for me -
python -m pip install flask
Just follow the requirements listed on the project's page: https://pypi.org/project/pgmagick/
might help
sudo pip install wheel==0.29.0
Try installing flask through the powershell using the following command.
pip install --isolated Flask
This will allow installation to avoide environment variables and user configuration.
Although it doesn't really answers this specific question. Others got the same error message with this mistake.
For those who like me initial forgot the -r
: Use pip install -r requirements.txt
the -r
is essential for the command.
