Permission denied error by installing matplotlib
Question:
I installed opencv with all dependencies. After the installation I tried to import matplotlib for a simple example.
Then I got the following error, when I tried to install matplotlib via pip with pip install matplotlib:
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packages/kiwisolver.cpython-35m-x86_64-linux-gnu.so'
Consider using the `--user` option or check the permissions.
What can I do to install matplotlib?
Answers:
It looks like your user does not have the permission to install packages in your system (for all users). Here’s how to fix this problem for Linux, macOS and Windows.
Linux / macOS
From your terminal, you can install the package for your user only, like this:
pip install <package> --user
OR
You can use su or sudo from your terminal, to install the package as root:
sudo pip install <package>
Windows
From the Command Prompt, you can install the package for your user only, like this:
pip install <package> --user
OR
You can install the package as Administrator, by following these steps:
- Right click on the Command Prompt icon
- Select the option
Run This Program As An Administrator
- Run the command
pip install <package>
Try this:
sudo pip install matplotlib
I solved this issue by typing the following command,
pip install --user <package_name>
Example,
pip install --user tensorflow
NOTE: You should not enter your own username for this command. Please enter with ‘–user’.
You don’t have the permission to install a package globally, so you can use sudo pip install matplotlib, but it isn’t recommended.
The recommended way is using venv or virtualenv to create a virtual environment.
venv:
- Create a python virtual environment, command:
python3 -m venv <DIR>
- Activate the virtual environment, command:
source <DIR>/bin/activate
- Install matplotlib, command:
pip install matplotlib
