Offering intelligent code recommendations, debugging help, and even autonomous authoring of code blocks, GitHub Copilot has become a reliable co-pilot for engineers. But what if your IDE Copilot stops functioning properly? Often, if Copilot is not working as intended, it is because of IDE compatibility problems—especially with older versions of JetBrains or VS Code.
This article will bring you through a step-by-step approach to resolve version problems and restore GitHub Copilot functioning properly. This guide has you covered whether you’re using JetBrains-based IDE or VS Code.
Common Causes of IDE Compatibility Issues with Copilot
Before we jump into the fixes, it’s helpful to understand the most common culprits behind the problem:
- Running an outdated version of VS Code or JetBrains
- Incomplete or corrupt IDE updates
- Unsupported programming languages or file types
- Plugin conflicts or misconfigurations
- Copilot plugin not detecting the IDE properly
Let’s break it down and resolve the issue.
Fixing Compatibility Issues in Visual Studio Code (VS Code)
Step 1: Check Your VS Code Version
One of the most common version issues is running an outdated editor.
- Open VS Code
- Go to Help > About or Code > About (macOS)
- Ensure your version is v1.57 or higher (Copilot’s minimum requirement)
If you’re running an older version:
- Visit https://code.visualstudio.com/Download
- Download and install the latest release
- Restart your machine after installation
📌 Tip: Keeping your editor up-to-date is the first line of defense against compatibility issues.
Step 2: Update GitHub Copilot Extension
Even with the right IDE version, an outdated plugin can trigger IDE compatibility issues.
- Go to Extensions
- Search for GitHub Copilot
- Click Update, or uninstall and reinstall the extension
- Restart VS Code
Step 3: Enable Auto-Update for Extensions
Prevent future problems by automating updates:
- Open Settings
- Search for Extensions: Auto Update
- Make sure it’s toggled ON
Step 4: Disable Conflicting Extensions
Sometimes other extensions interfere with Copilot’s performance:
- Open the Extensions Panel
- Temporarily disable linters, older AI assistants, or autocomplete tools
- Restart VS Code and re-test Copilot
Fixing Compatibility Issues in JetBrains IDEs (IntelliJ, PyCharm, WebStorm, etc.)
Step 1: Confirm IDE Version
GitHub Copilot supports JetBrains IDEs v2021.2 and above.
To check:
- Go to Help > About
- Take note of the version
If outdated:
- Open JetBrains Toolbox
- Click Update next to your IDE
- Or download the latest installer from https://jetbrains.com
- Restart your system
Step 2: Update Copilot Plugin
Keeping the plugin in sync with the IDE version helps eliminate version issues.
- Go to Settings > Plugins
- Search GitHub Copilot
- Click Update or reinstall
- Restart your IDE
Step 3: Enable Copilot in Settings
Make sure Copilot is properly configured:
- Go to Settings > Tools > GitHub Copilot
- Ensure it’s enabled for your current project and language
Step 4: Clear Plugin Cache
Corrupted cache data can lead to unexpected IDE compatibility issues.
- Close your JetBrains IDE
- Navigate to:
Windows: C:\Users\<username>\.cache\JetBrains
macOS: ~/Library/Caches/JetBrains/
- Delete any GitHub Copilot-related folders
- Reopen your IDE and reinstall the plugin
What If Nothing Works?
If Copilot is still not working after all these steps:
- Fully uninstall and reinstall your IDE
- Create a new user profile to test fresh settings
- Switch IDEs (e.g., try Copilot on VS Code if JetBrains fails, or vice versa)
- Contact GitHub Support for personalized help
Pro Tips to Avoid Compatibility Issues in the Future
- Always update your IDE and plugins regularly
- Avoid using beta releases unless they are supported by Copilot
- Enable automatic updates in JetBrains Toolbox or VS Code settings
- Bookmark GitHub Copilot’s documentation for version support
- Test plugins in a sandbox project before applying to your main workflow
