I have been trying to build the https://github.com/SharePoint/sp-dev-fx-webparts

I have gone through the instructions and reinstalled and installed but no luck I am now getting the error:

Cannot find module @microsoft/sp-build-web

Any ideas what I am doing wrong here. This happens after running - gulp build or gulp serve.

Thanks in Advance.

Thanks in Advance.

  • Which version of nodeJS you have? and did npm install @microsoft/sp-build-web complete successfully or it gives any error? – Anil Pal Dec 11 '19 at 6:27
  • Node V 10 and yes it gave some error as in my original post – naijacoder Dec 16 '19 at 6:54

@microsoft/sp-build-web should be installed when you run npm install the first time.

In package.json, this is referenced in the devDependencies section:

"devDependencies": {
    "@microsoft/sp-build-web": "1.4.1",
    "@microsoft/sp-module-interfaces": "1.4.1",
    "@microsoft/sp-webpart-workbench": "1.4.1",
    "@types/chai": "3.4.34",
    "@types/mocha": "2.2.38",
    "@types/prop-types": "ts2.4",
    "ajv": "~5.2.2",
    "gulp": "~3.9.1",
    "webpack-bundle-analyzer": "^2.13.1"

As to why this was not installed in your case, there seems to be an issue with this particular sample.

Reference: Keep getting "Verification failed while extracting @microsoft/sp-polyfills@1.2.0".

To correct this, delete the file package-lock.json and run npm install again.

  • Getting there with some of the sample and thanks guys.I keep running npm as the error occurs and I go to package one sample. Also I think deleting the package-lock.json also did help alot – naijacoder Dec 16 '19 at 6:56
