In my MacOS Mojave terminal I wanted to install a python package with pip. At the end it says:
You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
So I wanted to update pip with the given command but I got an error:
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied:
'/Library/Python/2.7/site-packages/pip-18.0-py2.7.egg/EGG-INFO/PKG-INFO'
Consider using the `--user` option or check the permissions.
I don't really understand what to do now. Also I realized it says Python 2.7 in the error message but I have and want to use only python 3.
If you want to use python3+ to install the packages you need to use pip3 install package_name
And to solve the errno 13 you have to add --user at the end
pip3 install package_name --user
EDIT:
For any project in python it's highly recommended to work on a Virtual enviroment, is a tool that helps to keep dependencies required by different projects separate by creating isolated python virtual environments for them.
In order to create one with python3+ you have to use the following command:
virtualenv enviroment_name -p python3
And then you work on it just by activating it:
source enviroment_name/bin/activate
Once the virtual environment is activated, the name of your virtual environment will appear on left side of terminal. This will let you know that the virtual environment is currently active.
Now you can install dependencies related to the project in this virtual environment by just using pip.
pip install package_name
Regarding the permissions command, try using sudo in front of your terminal command:
sudo pip install --upgrade pip
Sudo allows you to run the command with the privileges of the superuser and will install the package for the global, system-wide Python installation. Ideally, you should create a virtual environment for the project you are working on. Have a look at this
Regarding the python Try running pip as an executable like this:
python3.6 -m pip install <package>
I was making the same mistakes then I realized that I have created my virtual environment as root user. It was write protected, so please check whether your virtual environment is write protected. make a new venv and try again
