Can't install Solargraph in MacOS, but installed in Lima, but VSCode says solargraph command not found

[lulunac27a]

I installed Solargraph in Lima, but it's not working in VSCode because it says command not found: solargraph in extension output because I tried to install Solargraph on MacOS, but it's failed, but I try to use external server:

"solargraph.transport": "external",
  "solargraph.externalServer": {
    "host": "localhost",
    "port": 7658
  }

but it failed with the same error above.
