The bundled DFX option allows you to use the Dashboard even if dfx is not installed on your system, which can be useful for quick setups or testing. The current system dfx version is displayed next to the toggle (e.g., “dfx 0.25.0”).
Profile File Management
When you update environment variables or set up shell completion through the DFX Dashboard, it intelligently manages your shell profile files:Cross-Platform Profile Support
macOS and Linux
macOS and Linux
Profile files checked and managed:
~/.bashrc- Primary bash configuration file~/.bash_profile- macOS fallback for bash~/.zshrc- Zsh shell configuration~/.profile- Generic shell profile~/.config/fish/completions/- Fish completion directory
Windows (WSL)
Windows (WSL)
Windows Subsystem for Linux support:
- Uses Linux-style profile files within WSL environment
- Supports bash, zsh, and fish shells in WSL
- Handles Windows-specific path considerations
- Integrates with WSL environment variables
File Management Strategy
File Management Strategy
Intelligent file handling:
- Updates the first existing file found in priority order
- Creates appropriate files if none exist
- Prevents duplicate entries in profile files
- Maintains proper file permissions and ownership
The Dashboard will attempt to update the first existing file it finds in the order listed above, or create the appropriate file if none exist. This ensures compatibility across different system configurations.

Troubleshooting
Configuration Issues
Configuration Issues
Common configuration problems and solutions:Problem: Changes don’t take effect
- Restart your terminal or the DFX Dashboard
- Source your profile file manually (e.g.,
source ~/.bashrc) - Check if changes were properly written to profile files
- Verify environment variable syntax and values
- Open a new terminal session to load new configuration
- Manually source the appropriate profile file
- Verify shell detection with
echo $SHELLcommand - Check completion file permissions and accessibility
Version and Cache Issues
Version and Cache Issues
Version management problems:Problem: Version compatibility problems
- Ensure dfx version is 0.25.0+ for full feature support
- Check project requirements against installed versions
- Verify version installation completed successfully
- Clear cache and reinstall if version appears corrupted
- Check internet connection for version downloads
- Verify write permissions to cache directory
- Ensure sufficient disk space for installations
- Clear corrupted cache entries and reinstall
