Python Forum

Hello - This question is directed at snippsat, but is information all forum viewers should see:

You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

my question is how to force venv to use proper pip version

Pictures are worth a thousand words:

Inside the venv you can also update pip:

pip install pip --upgrade

After the upgrade the venv is using the new pip version.

In the previous example, The local venv is /run/media/Larz60p/Data-2TB/venv
and the command:

pip install --upgrade pip

while running that virtual environment updates the proper pip.

I want it to be there when I create the venv, which if I understand correctly is created from my .pyenv environment
it already has pip 18.0 installed:

Output:
Larz60p@linux-nnem: ~:$which python
/home/Larz60p/.pyenv/shims/python
Larz60p@linux-nnem: ~:$python -V
Python 3.7.0
Larz60p@linux-nnem: ~:$which pip
/home/Larz60p/.pyenv/shims/pip
Larz60p@linux-nnem: ~:$pip -V
pip 18.0 from /home/Larz60p/.pyenv/versions/3.7.0/lib/python3.7/site-packages/pip (python 3.7)
Larz60p@linux-nnem: ~:$

however when I create a new virtual environment (before manual upgrade) it has the wrong pip version,
and then I have to manually upgrade:

example:

Output:
Larz60p@linux-nnem: ~:$mkdir ziggy
Larz60p@linux-nnem: ~:$cd ziggy
Larz60p@linux-nnem: ziggy:$which python
/home/Larz60p/.pyenv/shims/python
Larz60p@linux-nnem: ziggy:$python -V
Python 3.7.0
Larz60p@linux-nnem: ziggy:$which pip
/home/Larz60p/.pyenv/shims/pip
Larz60p@linux-nnem: ziggy:$pip -V

Larz60p@linux-nnem: ziggy:$
Larz60p@linux-nnem: ziggy:$python -m venv venv
Larz60p@linux-nnem: ziggy:$source ./venv/bin/activate

(venv) Larz60p@linux-nnem: ziggy:$pip -V
pip 10.0.1 from /home/Larz60p/ziggy/venv/lib/python3.7/site-packages/pip (python 3.7)

(venv) Larz60p@linux-nnem: ziggy:$which pip
/home/Larz60p/ziggy/venv/bin/pip
(venv) Larz60p@linux-nnem: ziggy:$

Yes, it's the right behavior.
The system wide installation of pip is copied or symlinked to your virtual environment.
The pip install command does not install system wide, when you're in a venv.
You could upgrade the system installation of pip or make a script, which upgrades pip after installing the env.

I'll just continue as I have done. It's a minor annoyance.
