Fix 'python -m pip install --upgrade pip'
tags: ros2 install python3 pip
Always stuck in this question:
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
Requirement already up-to-date: pip in /usr/local/lib/python2.7/dist-packages (19.0.3)
Solution:
cd /usr/local/lib/python2.7/dist-packages
sudo rm -rf pip-19.0.3.dist-info
sudo python -m pip install --upgrade pip
Continue to install ros2.
When you install python3 -m pip install -U you will get:
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '__init__.py'
Consider using the `--user` option or check the permissions.
The solution is to add a sudo in front.
