Conquering the "Non-zero exit code (1)" Error: Installing Cython on PyCharm in Windows 10
Getting the "Non-zero exit code (1)" error while trying to install Cython on your Windows 10 machine with PyCharm can be frustrating. This error usually signals a problem with the installation process, but don't worry, we've got you covered!
Scenario: You're excited to speed up your Python code with Cython and start your installation process on PyCharm. However, after selecting "Install Package" and entering "cython" in the search bar, you encounter the dreaded "Non-zero exit code (1)" error.

The error usually occurs during the package installation process within PyCharm's package manager.
Analysis and Clarification:
This error commonly arises from:
- Missing Dependencies: Cython requires specific compilers to build its extensions. These compilers are often not included in the default Windows installation.
- Incorrect Environment: The error might occur if PyCharm is attempting to install Cython in the wrong environment.
- Permission Issues: Insufficient permissions can also lead to the error.
Troubleshooting and Solutions:
-
Install the Missing Compiler: The most likely cause is the absence of a suitable compiler. Here's how to fix it:
- Install the Microsoft Visual C++ Build Tools: Go to https://visualstudio.microsoft.com/downloads/ and download the "Visual C++ Build Tools" package.
- Install the MinGW-w64 Compiler: MinGW-w64 is another popular choice. Download the appropriate version from https://www.mingw-w64.org/ and install it.
-
Verify Your PyCharm Environment:
- Ensure the correct environment is selected: In PyCharm, navigate to "File > Settings > Project: [Your Project Name] > Project Interpreter". Make sure the correct Python environment where you want to install Cython is selected.
- Create a new virtual environment: If you're working on a new project, it's always a good practice to use a virtual environment to isolate dependencies. This can be done from the "Project Interpreter" settings.
-
Run PyCharm as Administrator:
- Right-click on the PyCharm shortcut and select "Run as administrator". This can sometimes fix permission-related issues.
-
Clean and Reinstall Cython:
- Remove existing installation: If you've tried the above steps and the error persists, try removing the existing Cython installation from your PyCharm environment.
- Clean the project cache: Go to "File > Invalidate Caches / Restart" and select "Invalidate and Restart".
- Reinstall Cython: After restarting PyCharm, attempt to install Cython again using the package manager.
Additional Tips:
- Update Pip: Make sure your pip package manager is up-to-date by running the command
python -m pip install --upgrade pipin your terminal or command prompt. - Check for conflicts: If you have other packages that might conflict with Cython, try temporarily disabling them and attempting the installation again.
- Consult online resources: For more advanced troubleshooting, search online for specific error messages related to Cython and your operating system. You might find helpful solutions and discussion forums.
Remember: If you encounter any specific error messages, provide them in your search queries for more relevant results.
By following these steps, you should successfully overcome the "Non-zero exit code (1)" error and install Cython on your Windows 10 machine with PyCharm. Happy coding!
