如何抑制pip升级警告？

Question

我的pip版本已关闭-每个pip命令都说：

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.

而且我不喜欢这里给出的答案：如何摆脱从pip升级的警告？因为他们都希望pip与RH版本不同步。

因此，我尝试使用此VagrantFile安装干净的系统：

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

但是后来我得到了：

==> 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.

因此，似乎我使用了错误的命令进行安装pip。使用正确的命令是什么？

创建一个pip配置文件并设置disable-pip-version-check为true

[global]
disable-pip-version-check = True

在许多linux上，pip配置文件的默认位置是$HOME/.config/pip/pip.conf。Windows，macOS和virtualenvs的位置太多，无法在此处详细说明。请参考文档：
