Fixing Python Installation Issues

After a fresh install of Clarisse, Clarisse may prompt you with an error message regarding a Python installation issue.

Clarisse Python Error Message

Please note that sometimes this error message is not displayed however, you only can see File > Quit in Clarisse’s application main menu bar. These problems typically occur when:

Either case, it shouldn't take more than 5-15 mins to solve the problem! But before finding the right solution, we first have to identify what’s the issue with your installation.

A. Checking Python Installation

Press Cmd + Space to open Spotlight, type Terminal and then press the Enter key. In the Terminal type python and press the Enter key. If you have a error message such as:

-bash: python: command not found

Then Python is not installed and you need to go to Step B

However, if you see a command-line window displaying a message such as:

Python 3.7.6 (v3.7.6:43364a7ae0, Dec 18 2019, 14:18:50) [Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Then Python is properly installed and you can directly skip to Step C

B. Making a clean installation of Python 3.7.x 64-bit

Our goal here is to install the proper version of Python

1. Download Python 3.7.9 64-bit

2. Install it

3. Launch Clarisse and if the problem persists go to Step C

C. Editing clarisse.env file

Our goal here is to find where python is installed on the system.

1. Press Cmd + Space to open Spotlight, type Terminal and then press the Enter key. In the Terminal, type python and press the Enter key.

2. In the python shell, type import sys;print(sys.path) and press Enter key. You should get something like this:

['', '/Library/Frameworks/Python.framework/Versions/3.7/lib/',

In this example we can see Python is installed in /Library/Frameworks/Python.framework/Versions/3.7

3. Now go to this location /Users/YourUserName/Library/Preferences/Isotropix/Clarisse. If you can't find the Library folder, it is because the folder hidden. Please follow this tutorial to resolve the issue.

Inside the folder, you should see a folder for each version of Clarisse you have installed (for example 3.6, 4.0, 5.0...). Go to the one you are troubleshooting. You will find a few files there. Open clarisse.env file using any text editor programs or create it if it doesn’t exist.

In our example, Python was installed in /Library/Frameworks/Python.framework/Versions/3.7. In clarisse.env file make sure you have:


4. Run Clarisse and that's it!
