Install Python 3 3 On Bsd Desktop
IntroductionPython is a versatile programming language that can be used for many different programming projects. First published in 1991 with a name inspired by the British comedy group Monty Python, the development team wanted to make Python a language that was fun to use. Easy to set up, and written in a relatively straightforward style with immediate feedback on errors, Python is a great choice for beginners and experienced developers alike. Python 3 is the most current version of the language and is considered to be the future of Python.This tutorial will guide you through installing Python 3 on your local Windows 10 machine and setting up a programming environment via the command line.
PrerequisitesYou will need a Windows 10 computer with administrative access that is connected to the internet. Step 1 — Opening and Configuring PowerShellWe’ll be completing most of our installation and setup on a command-line interface, which is a non-graphical way to interact with your computer. That is, instead of clicking on buttons, you’ll be typing in text and receiving feedback from your computer through text as well. The command line, also known as a shell, can help you modify and automate many of the tasks you do on a computer every day, and is an essential tool for software developers.PowerShell is a program from Microsoft that provides a command-line shell interface.
Administrative tasks are performed by running cmdlets, which are pronounced command-lets, specialized classes of the.NET software framework that can carry out operations. Open-sourced in August 2016, PowerShell is now available across platforms, for both Windows and UNIX systems (including Mac and Linux).To find Windows PowerShell, you can right-click on the Start menu icon on the lower left-hand corner of your screen. When the menu pops up, you should click on “Search,” then type “PowerShell” into the search bar. When you are presented with options, right-click on “Windows PowerShell,” the Desktop app. For our purposes, we’ll select “Run as Administrator.” When you are prompted with a dialogue box that asks “Do you want to allow this app to make changes to your PC?” click on “Yes.”Once you do this, you’ll see a text-based interface that has a string of words that looks like this:We can switch out of the system folder by typing the following command:. cd Then we’ll be in a directory such as PS C:Users Sammy.To continue with our installation process, we are going to set up some permissions through PowerShell. Output Scope ExecutionPolicy- -MachinePolicy UndefinedUserPolicy UndefinedProcess UndefinedCurrentUser RemoteSignedLocalMachine UndefinedThis confirms that the current user can run trusted scripts downloaded from the internet.

We can now move on to downloading the files we will need to set up our Python programming environment. Step 2 — Installing the Package Manager ChocolateyA package manager is a collection of software tools that work to automate installation processes that include the initial installation, upgrading and configuring of software, and removing software as needed. They keep software installations in a central location and can maintain all software packages on the system in formats that are commonly used.Chocolatey is a command-line package manager built for Windows that works like apt-get does on Linux. Available in an open-source version, Chocolatey will help you quickly install applications and tools, and we will be using it to download what we need for our development environment.Before we install the script, let’s read it to confirm that we are happy with the changes it will make to our machine. To do this, we will use the.NET scripting framework to download and display the Chocolatey script within the terminal window.
We’ll create a WebClient object called $script (you can call it whatever you want as long as you use $ as the first character), that shares Internet connection settings with Internet Explorer:. $script = New-Object Net.WebClientLet’s look at the options that we have available to us by piping the object to the Get-Member class to return all members (properties and methods) of this WebClient object:. $script Get-Member. OutputEnvironment Vars (like PATH) have changed. Close/reopen your shell toSee the changes (or in powershell/cmd.exe just type 'refreshenv').The install of python3 was successful.Software installed as 'EXE', install location is likely default.Chocolatey installed 1/1 packages. 0 packages failed.See the log for details (C:ProgramDatachocolateylogschocolatey.log).With the installation finished, you’ll want to confirm that Python is installed and ready to go. To see the changes, use the command refreshenv or close and re-open PowerShell as an Administrator, then check the version of Python available to you on your local machine:.
python -VYou should get output such as. OutputPython 3.7.0Alongside Python, pip will be installed, which will manage software packages for Python. Let’s ensure that pip is up-to-date by upgrading it:. python -m pip install -upgrade pipWith Chocolatey, we can call Python 3 with the python command.
We will use the -m flag to run the library module as a script, terminating the option list, and from there use pip to install its upgrade.Once Python is installed and pip updated, we can set up a virtual environment for our development projects. Step 5 — Setting Up a Virtual EnvironmentNow that we have Chocolatey, nano, and Python installed, we can go on to create our programming environment with the venv module.Virtual environments enable you to have an isolated space on your computer for Python projects, ensuring that each of your projects can have its own set of dependencies that won’t disrupt any of your other projects.Setting up a programming environment provides us with greater control over our Python projects and over how different versions of packages are handled. This is especially important when working with third-party packages.You can set up as many Python programming environments as you want.

OutputHello, World!To leave the environment, simply type the command deactivate and you will return to your original directory. At this point you should have a Python 3 programming environment set up on your local Windows 10 machine and can begin a coding project!To set up Python 3 on another computer, follow the for,. You can also read about, which is especially useful when working on development teams.With your local machine ready for software development, you can continue to learn more about coding in Python by following “” and “”.

Sometimes you do need to install from ports still, most often when you need to change one of the build-time options. In that case, I usually install the package first so I get all of the dependencies. Then I move to ports, check what is still missing (build dependencies) using make missing and install those via packages, then modify the config ( make config or make config-recursive) and build the package. Only trick is you need to do make reinstall, since we already installed the software using the package.Most likely, it is taking forever because it's building a bunch of dependencies. My FreeBSD is almost bear-bones VM. It has nothing on it.not GCC, nothing.Other problem is when you build those ports, they prompt up the screen so that you need to select some option or select default to proceed.I use Tmux to run it in the background, but I need to login to the VM, and see what is happening, if they prompt up some screen, then I need to press some buttons or select default to install other dependency,How can you build the port without prompting screen, or select all the default installation. I think BATCH isn't the default because nowadays most people building from ports are doing so specifically to muck about with those settings.Often we see people that used FreeBSD back in the day (when ports was the only option, or when we had the (IMHO terrible) pkgadd tool) and are coming back after a hiatus aren't aware that FreeBSD has the pkg package manager.
Not to mention the fact that pkg is actually a pretty darn good package manager.Also, make config-recursive can be useful.
