I need to use TS2.4 to reproduce this due to #17138.
Can reproduce this with just a JS file containing: require("jsdom").

My hypothesis is that this is because parse5 (a dependency of jsdom) has a dependency on @types/node version 6, while the latest version is 8, causing those types to be stored in typescript/2.4/node_modules/parse5/node_modules/@types/node/index.d.ts instead of typescript/2.4/node_modules/@types/node/index.d.ts. Somewhere we must be assuming that the node_modules cache is flat.

Can't reproduce it with just require("parse5"); presumably because we need 2 versions of @types/node in existence to trigger the error.

The error is likely that in getReferencedFileInfos getReferencedFiles to get all referenced files, which for parse5 will include its node_modules/@types. We then call getOrCreateFileInfo, which calls getScriptInfo. getScriptInfo calls getOrCreateScriptInfoForNormalizedPath, but then asserts that the result must already be attached to this project, so it must be expecting to just have gotten an existing scriptInfo and not created one.

Thanks for looking into this @Andy-MS!

@rbuckton We're seeing a number of users reporting this in a variety of different cases. Can we please prioritize this for TS 2.4.2

Talked to @sheetalkamat and it looks like this was fixed by #16539.
Now that #17210 is in there should be nothing blocking me from reproducing this in master, but I can't.

[rbuckton]

This does look to have been fixed by #16539. I've merged this into release-2.4.

Yes I review must of the other related threads but this is still an issue for me.

The latest build of VS Code with TypeScript 2.4.1, Express and MongoDB only has partial Intellisense enabled for the modules imported via the .ts file. TypeScript adds Express and MongoDB index.d.ts files to its @types folder there's very little documentation available. If you can image, this reduces my productivity dramatically. Any suggestions on resolving this. My repo is Rescue Shelter

Also, is there anyway to include the actual JSDoc located in the node_module folder specifically?

@kscott5 Can you try this out with typescript@next? See the docs for how to set that up.

[kscott5]

I will review the document. I did find this post on Angular University blog. It brief explain @type declaration and why the suggest using the noImplicityAny: true flag updated in tsconfig.json, and although it didn't resolve the issue complete it helped.

MODIFIED:
@Andy-MS Thank you for the suggestion. Both provided the information I needed and gave me a few minutes to refocus and review my code. I'm working!
