To fix the 'lean' or 'lake' command not found error, you must configure the Lean 4 toolchain PATH in your shell. This setup process detects missing commands and applies PATH augmentation so your terminal can resolve elan, lake, and lean executables correctly.
The best way to set up the Lean 4 toolchain PATH is by running OS-specific setup scripts provided for Windows and macOS/Linux. These scripts automatically apply the necessary environment configuration and integrate the toolchain directly into your shell.
VS Code requires proper PATH integration to run Lean 4 tasks and resolve toolchain commands. The setup provides specific guidance to augment the PATH environment, ensuring the editor can successfully locate and execute lean and lake commands.
Your Lean toolchain might not be recognized because the shell PATH lacks the correct elan directory entries. Troubleshooting this involves running script-based verification steps to ensure the environment configuration properly points to the installed toolchain binaries.
You can verify your Lean 4 environment configuration by running the `lean --version` command after executing the setup scripts. This checks that your terminal successfully resolves the toolchain and confirms the PATH augmentation is working.
