How can I install pip3 for Python 3 on Ubuntu 16.04 LTS while using a proxy server?

I’ve been trying to get my Python projects up and running on my Ubuntu 16.04 LTS, and I keep hitting this wall with pip3. I’ve got a proxy server set up in my network because of some security settings at my workplace, and I’m totally confused about how to install pip3 under these circumstances. It’s like every time I try to do anything related to Python or pip, it fails to connect or just throws me some errors about not being able to reach the internet.

I’ve tried following some online tutorials, but they usually just assume I have direct internet access, which isn’t the case for me right now. I think I need to pass some proxy settings while installing pip3, but I’m not exactly sure how to do that on Ubuntu. I’ve heard about using the `http_proxy` and `https_proxy` environment variables, but I’m a little lost on the details. Do I need to set these up system-wide or just for the terminal session when I’m trying to install pip?

Also, if I manage to get pip3 installed, will I need to do anything special to install packages through the proxy? Like, do I always have to specify the proxy settings every time I run a pip command? That sounds really tedious, and I just want to focus on writing my code without worrying about these networking hiccups.

It would be super helpful if someone could break it down step by step for me. Like, what commands do I actually need to run, and where do I place those proxy settings? Any tips or tricks that you’ve learned through your own experience would be fantastic, too! Seriously, I’m just looking for a straightforward way to get out of this pip3 jam so I can get back to coding without pulling my hair out. Thanks!

    1. Pip3 Installation with Proxy on Ubuntu

      Installing pip3 with Proxy on Ubuntu 16.04 LTS

      Sounds like you’re hitting a bit of a wall with pip3 and your workplace’s proxy. Don’t worry, it’s actually pretty straightforward once you get the hang of it!

      Step 1: Set the Proxy Variables

      You need to set the http_proxy and https_proxy environment variables. You can do this temporarily in your terminal or make it a permanent setup.

      Temporary Setup

      Open your terminal and run:

              export http_proxy=http://your_proxy_address:port
        export https_proxy=https://your_proxy_address:port

      Replace your_proxy_address and port with your actual proxy settings. These will only apply to the current terminal session.

      Permanently Setting the Proxy (Optional)

      If you want these settings to be available anytime, you can add them to your ~/.bashrc file:

              echo 'export http_proxy=http://your_proxy_address:port' >> ~/.bashrc
        echo 'export https_proxy=https://your_proxy_address:port' >> ~/.bashrc
        source ~/.bashrc

      Step 2: Install pip3

      Now you can install pip3. Use this command:

              sudo apt-get install python3-pip

      Since you’re behind a proxy, you might need to add the proxy settings during the installation. When asked for confirmation, just go ahead and say yes!

      Step 3: Using pip3 with Proxy

      After installing pip3, you’ll need to specify the proxy settings whenever you run pip commands. This is a bit annoying, but it’s pretty simple:

              pip3 install --proxy your_proxy_address:port package_name

      Swap out package_name with whatever package you want to install.

      Saving Time with pip.conf

      If you want to avoid typing the proxy every time, you can create a configuration file. Just create a file named pip.conf in your home directory under ~/.config/pip/:

              mkdir -p ~/.config/pip
        echo '[global]' > ~/.config/pip/pip.conf
        echo 'proxy = your_proxy_address:port' >> ~/.config/pip/pip.conf

      Final Tip

      Remember, if you change networks or need different proxy settings, you’ll need to update this file or temporarily set the environment variables again.

      Once you have everything set up, you should be back to writing your awesome code without too many interruptions!


    2. To install pip3 behind a proxy on Ubuntu 16.04 LTS, you need to set the `http_proxy` and `https_proxy` environment variables. This can be done either system-wide or just for the terminal session. To set these variables for the current session, you can run the following commands in your terminal:

      export http_proxy="http://your_proxy_address:port"
export https_proxy="http://your_proxy_address:port"

      Replace `your_proxy_address` and `port` with the appropriate values for your network. Once you’ve set these variables, you can proceed to install pip3 by running:

      sudo apt-get update
sudo apt-get install python3-pip

      If you manage to successfully install pip3, you will need to configure the proxy settings for package installations as well. You can do this by specifying the proxy every time you use pip, or you can configure it globally by creating or editing the `~/.pip/pip.conf` file. Add the following lines to the `pip.conf` file:

      [global]
proxy = http://your_proxy_address:port

      This way, you won’t have to specify the proxy each time you run a pip command. Just make sure to replace `your_proxy_address` and `port` with your network details. This setup should help you install packages smoothly and allow you to focus on your coding without having to deal with the networking issues repeatedly.
