Research direction

Reproduce rc-apps create with the reported Node, npm, and @rocket.chat/apps-cli versions. Start with the generated app's dependency and type setup, then inspect the IUploadRead.d.ts errors and the create.js command path mentioned in the trace. Done means a fresh scaffold completes without manually installing @types/node.

Workaround

Running npm install @types/node within the current working directoy where the command (rc-apps create) was issues, fixes the problem.

Environment

  • OS: macOS 10.15.3
  • Node: v13.8.0
  • NPM: 6.13.7
  • @rocket.chat/apps-cli: latest/1.6.0
