How to install Mu with Python packaging on Windows, OSX and Linux If you already have installed on your Windows, OSX or Linux machine then it is easy to install Mu with Python’s built-in package manager,. Please note: this method does not currently work on Raspberry Pi (use ). If you’re on Windows and would rather not type commands you should use the instead. If you’re using OSX on a Mac and want to use the simple drag-and-drop installer instead, you should use the. We recommend you run the following commands in a or other means of isolating your Python environment. At your OS’s command prompt (see below) type the following command. Depending on how your machine is set up, you may encounter errors.
The most common are:. You don't have permission to use pip to install packages, in which case, talk to whoever administers your computer and ask them to install Mu for you (just point them to this website).
You're using the wrong or and old version of pip. If you have Python 2 installed on your machine, you must make sure you're using pip3. If pip complains it is out of date, follow these. You can't even run pip, in which case check you have Python 3 installed and that when Python was installed, you clicked the option that asks you if you'd like Python added to your path (you do). If you're still facing problems, perhaps try using another installation method (HINT: if you're on Windows or using OSX on a Mac, use the installer for the appropriate platform instead). As a last resort why not see if anyone can help you in the.
What is a Command Prompt? Most people use a graphical user interface (GUI) on their computer: basically, windows and icons controlled with a mouse and pointer. However, it’s also possible to control your computer by typing commands into a prompt. Once you know the commands, this is often the most powerful way to use a computer.
However, it can feel a bit like casting spells with incomprehensible incantations so may, at first, appear frightening. Find your computer’s command prompt depends upon which operating system you’re using:. Windows: in the search area of your start menu, type cmd and press enter. Mac OSX: use the finder to go to the Applications folder and then the Utilities folder. Open the “Terminal” app. Linux: look for the “Terminal” app in your desktop’s menu. I Want a Shortcut!
When pip installs software it doesn’t automatically create a shortcut or menu item for you. Happily, someone has created a utility called shortcut to do this for you if you’ve not isolated Mu in a virtualenv. Simply use pip to install shortcut and then use shortcut on Mu.
Every Python developer who uses Mac OS comes across the problem of whether to use the pre-installed python 2.7 on Mac or update it to Python 3, to start developing on the latest python version. Although Python 2.x is still popular and being actively used for developing products, but if you are starting afresh then I would advice to choose Python 3.x, as sooner or later you will have to move to it, so why not today.
Updating the Pre-installed Python 2.x in Mac OS You cannot do that. As the Mac OS wouldn't allow you to do so because it uses Python and cannot afford a change in it's version as that may lead to errors or failures at the OS level. How to install Python 3 To install Python 3 we will be using Homebrew.
Homebrew is a software package manager which makes it very easy to install, update, cofigure and uninstall software packages required in OS X. If you do not have Homebrew installed on your Mac, follow our to set it up on your system. Considering that you have successfully setup Homebrew, let's start with Python 3 installation. Step 1 As you can see in the Homebrew installation guide, you can search for available software packages using the brew search command. $ brew search python This command will return a list of all the available packages for python, you will also see python3 in the list, and that is what we need. So let's install it: $ brew install python3 It may take a few minutes as a lot of packages and dependencies are downloaded, you can see what Homebrew is doing on the screen logs.
Alongside Python 3, pip, setuptools and wheel will also be installed. Pip is used to install and manage libraries and packages that we want in our python development environment.

We can use pip as follows: $pip3 install packagename Just like we do for Homebrew, but pip will install only python libraries and software packages within the python environment. Step 2 To check the version of python installed, use the following command: $ python3 -version Step 3 To update the Python 3 installation, we can use Homebrew, $ brew update python3 How to Create a Virtual Environment To setup virtual Environment, we can use the module provided by Python 3. While in Python 2.x is used. So we will be using the venv module.

Setting up virtual environment allows us to setup independent environment for different projects, with different dependencies. We can setup as many python virtual environment as we want. Let's setup our very own virtual environment.
Step 1 Choose a directory to put Python programming environment in, or create a new directory. I suggest, if you are starting up with python, create a new directory. Go to the directory in which you want to create a new directory for python environment. $ mkdir Environments $ cd Environments mkdir is a command used to create directory and using cd command we can open that directory, and that is exactly what we have done. Step 2 Once we are inside the directory, run the following command to create an environment: $ python3.6 -m venv myfirstenv This will create a new directory/folder for your virtual environment by the name myfirstenv. It will contain it's own copy of python version in lib/ subdirectory along with a subdirectory site-packages/ to store third party modules that you will install in this virtual environment. It will also have a pyenv.cfg file with python installation configuration.
Step 3 To start using this new environment, run the following command: $ source myfirstenv/bin/activate As you run this command, you will see a prefix added to your terminal like this, (myfirstenv) Username: username$ This means that if we run any python script now, it will be run as per the current environment's settings and packages. NOTE: Withing the virtual environment we can use command python and pip instead of python3 and pip3 respectively. Setup of your virtual environment is complete.
