Definitelytyped: Invalid 'reference' directive syntax

@sanex3339 can you close this issue if your problem is fixed as well?

I'm using typescrpit version 2.7, and I still encounter this error for the following:

/// <reference types="angular" />

I had the same issue as https://github.com/DefinitelyTyped/DefinitelyTyped/issues/10097#issuecomment-499826179

Temporary solution for this
Remove one / from /// on line number 7 in file node_modules/@types/pdfjs-dist/index.d.ts

Hope this issue is solved ASAP!!!

I had the same issue as #10097 (comment)

I confirm that works. Thanks

An other solution is to use the verision "typescript": "3.5.1" and not other :(

the modification is to do in package.json file in the bloc: "devDependencies": {}

Removing a slash from the triple slash makes it a normal comment. Just remove it in that case. If you can still compile, it probably wasn't needed anymore.

Confirm resolve using "typescript": "3.5.1".

use command "npm i [email protected]"

Best solution so you don't need to change your package.json, Especially if you are using version control.

I 've had the same issue and updating to typescript 3.5.1 was not an option.
What I've done is using the version for pdfjs-dist that match with my typescript version and so the matching version for ng2-pdf-viewer.
Here are the different version I used :
Typescript @2.7.2
ng2-pdf-viewer @5.2.4
@types/pdfjs-dist @0.1.2

Removal of one / from /// at line no 7 works
my ts was 2.7.2

Hey guys!

This worked for me:

npm i [email protected] --save
npm i [email protected] --save

This is due to on my end,

💬-> npm ls typescript
├─┬ @ionic/[email protected]
│ └─┬ @angular-devkit/[email protected]
│   └── [email protected] 

Typescript is forced to 2.6.2 max due to the dependencies as shown.

You may have different issues depending on your npm ls typescript adventure.

Don't forget to restart ionic serve or something similar.

It's worked for me too. Thanks!!!

I modified any line in index.d.ts file, save my changes, and compile, my change was a space

use command "npm i [email protected]"

Worked for me

use "npm i [email protected]" |
Worked for mee

I had the same issue while building package "nest-schedule/0.6.4".
Installing typescript v3 with npm install [email protected] solved it.

Thanks a lot for that help here.

Remove one / from /// on line number 7 in file node_modules/@types/pdfjs-dist/index.d.ts

Removing extra '/' helps to remove error : "Invalid 'reference' directive syntax. webpack : Failed to Compile."
Thank you.
