How to upgrade pip3?
PythonLinuxPython 3.xPython Problem Overview
I want to use python3.5 for development, but many times when I install the module for python 3.5, it always fails. The terminal tells me that a higher version is available, but it doesn't work when I upgrade it.
Python Solutions
Solution 1 - Python
You are using pip3 to install flask-script which is associated with python 3.5. However, you are trying to upgrade pip associated with the python 2.7, try running pip3 install --upgrade pip.
It might be a good idea to take some time and read about virtual environments in Python. It isn't a best practice to install all of your packages to the base python installation. This would be a good start: http://docs.python-guide.org/en/latest/dev/virtualenvs/
Solution 2 - Python
To upgrade your pip3, try running:
sudo -H pip3 install --upgrade pip
Your pip may move from /bin to /usr/local/bin
To upgrade pip as well, you can follow it by:
sudo -H pip2 install --upgrade pip
Solution 3 - Python
Try this command:
pip3 install --upgrade setuptools pip
Solution 4 - Python
First decide which pip you want to upgrade, i.e. just pip or pip3. Mostly it'll be pip3 because pip is used by the system, so I won't recommend upgrading pip.
The difference between pip and pip3 is that
> NOTE: I'm referring to PIP that is at the BEGINNING of the command > line.
> pip is used by python version 2, i.e. python2
and
> pip3 is used by python version 3, i.e. python3
For upgrading pip3: # This will upgrade python3 pip.
pip3 install --upgrade pip
For upgrading pip: # This will upgrade python2 pip.
pip install --upgrade pip
This will upgrade your existing pip to the latest version.
Solution 5 - Python
The Problem
You use pip (the Python 2 one). Now you want to upgrade pip (the Python 3 one). After that, pip is the Python 3 one.
The solution
Use pip2 and pip3. This way it is explicit.
If you want to use pip, just check where it is (which pip) and change the link. For example:
$ which pip
/usr/local/bin/pip
$ pip --version
pip 9.0.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)
$ which pip2
/usr/local/bin/pip2
$ sudo rm /usr/local/bin/pip
$ sudo ln -s /usr/local/bin/pip2 /usr/local/bin/pip
$ pip --version
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

-
for Python 3:
python3 -m pip install --upgrade pip -
for Python 2:
python2 -m pip install --upgrade pip
Solution 7 - Python
What worked for me was the following command:
python -m pip install --upgrade pip
Solution 8 - Python
pip3 install --upgrade pip worked for me
Solution 9 - Python
In Ubuntu 18.04, below are the steps that I followed.
python3 -m pip install --upgrade pip
For some reason you will be getting an error, and that be fixed by making bash forget the wrongly referenced locations using the following command.
hash -r pip
Solution 10 - Python
If you have 2 versions of Python (eg: 2.7.x and 3.6), you need do:
- add the path of 2.x to system PATH
- add the path of 3.x to system PATH
pip3 install --upgrade pip setuptools wheel
for example, in my .zshrc file:
export PATH=/usr/local/Cellar/python@2/2.7.15/bin:/usr/local/Cellar/python/3.6.5/bin:$PATH
You can exec command pip --version and pip3 --version check the pip from the special version. Because if don't add Python path to $PATH, and exec pip3 install --upgrade pip setuptools wheel, your pip will be changed to pip from python3, but the pip should from python2.x
Solution 11 - Python
This worked for me (mac)
sudo curl https://bootstrap.pypa.io/get-pip.py | python
Solution 12 - Python
If you try to run
sudo -H pip3 install --upgrade pip3
you will get the following error:
WARNING: You are using pip version 19.2.3, however version 21.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
but if you upgrade using the suggested command:
pip install --upgrade pip
then, the legacy pip will be upgraded, so what I did is the following:
which pip3
and I located my pip3 installation (just in case the following command wouldn't upgrade the legacy pip. Then i changed to that directory and upgraded pip3 using the following commands: (your directory could be different)
cd /Library/Frameworks/Python.framework/Versions/3.8/bin
sudo -H pip3 install --upgrade pip
after this:
pip --version
will still show the legacy version, while
pip3 --version
will show pip 21.0.1
