vercel doctor
A diagnostic command of the Vercel CLI used to check the installation and configuration state of the CLI and to provide suggested fixes. It supports a non-interactive mode and JSON output, allowing the check to be run in automated environments and its results consumed programmatically. The command assists in identifying misconfiguration before deployment rather than resolving it automatically.
Timeline (last 90 days)
Vercel CLI has added the `vercel doctor` command, used to diagnose the CLI's installation and configuration status and provide fix suggestions.
`vercel doctor` checks the CLI version and installation status, and if `vercel upgrade` cannot update it, it displays where the CLI is running from and how to reinstall it.
`vercel doctor` verifies the user's login status and identifies the current team context.
`vercel doctor` checks whether the current directory is correctly linked to a Vercel project.
`vercel doctor` validates whether the configuration items in `vercel.json` are valid.
`vercel doctor` retrieves currently active incidents from the Vercel status page to help determine whether the problem originates from a platform-side outage.
Each check in `vercel doctor` returns one of four statuses: OK, Warning, Failed or Skipped.
`vercel doctor` supports running in environments without login or project linking, and does not pop up prompts, automatically log in or link projects.
Through the `--json` flag, `vercel doctor` can output the status and suggested command of each check in a structured format.
The non-interactive design of `vercel doctor` makes it suitable for coding agents to run diagnostics before fixing problems.
