My pip version was off -- every pip command was saying:
You are using pip version 6.0.8, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
And I didn't like the answers given here: How can I get rid of this warning to upgrade from pip? because they all want to get pip out of sync with the RH version.
So I tried a clean system install with this VagrantFile:
Vagrant.configure("2") do |config|
config.ssh.username = 'root'
config.ssh.password = 'vagrant'
config.ssh.insert_key = 'true'
config.vm.box = "bento/centos-7.3"
config.vm.provider "virtualbox" do |vb|
vb.cpus = "4"
vb.memory = "2048"
end
config.vm.synced_folder "..", "/vagrant"
config.vm.network "public_network", bridge: "eth0", ip: "192.168.1.31"
config.vm.provision "shell", inline: <<-SHELL
set -x
# Install pip
yum install -y epel-release
yum install -y python-pip
pip freeze # See if pip prints version warning on fresh OS install.
SHELL
end
But then I got:
==> default: ++ pip freeze
==> default: You are using pip version 8.1.2, however version 9.0.1 is available.
==> default: You should consider upgrading via the 'pip install --upgrade pip' command.
So it seems that I'm using the wrong commands to install pip. What are correct commands to use?
There are many options (2021 update)...
Use a command line flag
pip <command> --disable-pip-version-check [options]
Configure pip from the command line
pip config set global.disable-pip-version-check true
Set an environment variable
export PIP_DISABLE_PIP_VERSION_CHECK=1
Use a config file
Create a pip configuration file and set disable-pip-version-check to true
[global]
disable-pip-version-check = True
On many linux the default location for the pip configuration file is $HOME/.config/pip/pip.conf. Locations for Windows, macOS, and virtualenvs are too various to detail here. Refer to the docs:
