Please check the build logs for more information.
See Builds for ideas on how to fix a failed build, or Metadata for how to configure docs.rs builds.
If you believe this is docs.rs' fault, open an issue.
Unfortunately deno developers won't distribute code from deno/cli as a library.
So this is stripped-down code temporary (I hope) taken from https://github.com/denoland/deno/tree/main/cli to make better compatibility.
Periodically it will synced with original repository.
