for Mac

This lab is for those who are installing PyCharm on Mac machines.

Installation

1. Download PyCharm.

2. Locate the downloaded .dmg file and click to open. Drag PyCharm into the Applications folder.

3. Open your Finder, select Applications, then PyCharm.

4. You may wish to pin PyCharm to your dock after launching.

Enable launching PyCharm from the Terminal

1. Open the Mac Terminal application as described in the Launching a Terminal lab.
2. In the Terminal, type the command

   
   sudo nano /usr/local/bin/pycharm
   

3. Enter your password when prompted.
4. You will now see the Nano text editor in your terminal. Type or paste in the following:

   
   #!/bin/sh
   
   open -na "PyCharm.app" --args "$@"
   

   

5. Hit Control+O to save, then Enter to accept the filename.
6. Hit Control+X to exit the text editor.
7. Run the following command in the Terminal:

   
   sudo chmod +x /usr/local/bin/pycharm
   

You will now be able to type pycharm . in the Terminal to open PyCharm to edit the current directory’s contents.

Test drive

We are going to create a sample project directory using the Terminal, then open PyCharm and edit files in that directory. A video follows the steps.

1. Open the Terminal application.
2. Run the following in the Terminal:

   
   cd ~                # make sure in your home directory
   mkdir seng-201      # This directory will hold all our code for the course
   cd seng-201         # change to the new directory
   mkdir pycharm-test  # Make a new subdirectory for a test project.
   cd pycharm-test     # change into the subdirectory
   pycharm .           # launch PyCharm in the current directory
   

   The pycharm command launches the PyCharm program. The command pycharm . says launch Pycharm and have it open the current working directory. The symbol . always means the working directory. Sometimes it will be necessary to explicitly tell the CLI we are referring to the working directory; more on those situations as they arise.
3. A PyCharm window will open after a moment.
4. You may be asked if you “trust the authors of the files in this folder”. Click the checkbox and then pick “Yes, I trust the authors.”

Here is the process in a video:

Creating a new file

Let’s create a file in the Terminal in our project directory. We should see it immediately in PyCharm.

1. Go back to your Terminal and make sure you are in the pycharm-test directory.
2. Type the command touch hello.py to create an empty Python file.
3. Go back to PyCharm. You should see the file hello.py in the directory here. Click on it and it will open an empty editor pane.
4. In the code editor, type print("Hello World").
5. Go back to the Ubuntu Terminal and type cat hello.py. You should see the code.

Next

So you now have PyCharm successfully editing files and interacting with directories on Mac.

You are now ready to code! Move on to PyCharm Basics lab.
