DHTMLX Gantt编译报错TS6137、TS2306问题求助

Hey there, I’ve run into similar type declaration conflicts in TypeScript projects before—let’s walk through how to resolve these errors:

Why This Happens #

It sounds like either the @types/dhtmlxgantt package has been deprecated, or DHTMLX Gantt now includes its own built-in type declarations (a growing standard for modern libraries). TypeScript is throwing errors because it can’t treat the old standalone @types file as a valid module, and it’s warning you to import the library itself instead of the separate type package.

Step-by-Step Fixes #

• Uninstall the outdated type package
  First, get rid of the conflicting @types/dhtmlxgantt since it’s no longer needed:

  npm uninstall @types/dhtmlxgantt
  # or for yarn users:
  yarn remove @types/dhtmlxgantt
  

• Update DHTMLX Gantt to the latest version
  Make sure you’re using a version of dhtmlxgantt that includes native type support:

  npm update dhtmlxgantt
  # or
  yarn upgrade dhtmlxgantt
  

• Fix your import statements
  Replace any imports pointing to @types/dhtmlxgantt with direct imports of the library. For example:
  Before:

  import '@types/dhtmlxgantt';
  

  After:

  import 'dhtmlxgantt';
  

  If you need to import specific types (like config interfaces), you can do so directly from the library now:

  import type { GanttConfig } from 'dhtmlxgantt';
  

• Tweak your tsconfig.json (if needed)
  Ensure these settings are enabled to handle CommonJS-style imports smoothly:

  {
    "compilerOptions": {
      "esModuleInterop": true,
      "allowSyntheticDefaultImports": true
    }
  }
  

• Align TypeScript version with the demo
  If the official demo is also breaking, check its package.json for the TypeScript version it uses, and match yours to that. Sometimes newer TS versions have stricter rules that clash with older library setups.

Verify the Fix #

After making these changes, try rebuilding your project and running the official demo again—this should resolve both the TS2306 module error and the TS6137 import warning.
