Duplicate identifier errors when using @types inside a Windows junction #36294

Spongman · 2020-01-18T20:44:38Z

This is a dupe of #11333, but that issue was marked as closed/fixed (and locked... why?). It's not. It should be reopened and actually fixed. It's also unrelated to 'npm link'.

IMPORTANT:

my e:\work directory is a JUNCTION point to y:\work

node: 13.5.0
npm: 6.13.4
tsc: 3.7.5

index.ts:

/// <reference path="node_modules/@types/youtube/index.d.ts" />

package.json:

{
  "name": "junction-bug",
  "scripts": {
    "tsc": "tsc index.ts"
  },
  "devDependencies": {
    "@types/youtube": "0.0.38",
    "typescript": "^3.7.5"
  }
}

NOTE: There is NO reference to 'y:' in any of my project's files, nor in any of npm's files. tsc is erroneously converting relative paths to absolute paths on the destination drive. look for references to y:\ in the output below:

e:\work\junction-bug>dir e:\ | findstr work
04/19/2016  09:02 AM    <JUNCTION>     work [y:\work]

e:\work\junction-bug>npm i
...
e:\work\junction-bug>findstr /s /i /c:"y:\\" *

e:\work\junction-bug>npm run tsc

> junction-bug@ tsc E:\work\junction-bug
> tsc index.ts

This is a major issue when using workspaces in Yarn 2 or Yarn 3! 🙂

I was able to create a minimally reproducible example: https://github.com/Bosch-Eli-Black/hardlink-typescript-collisions

To reproduce the issue:

Use a Windows computer.
Clone the git repo (https://github.com/Bosch-Eli-Black/hardlink-typescript-collisions)
Run yarn install from the command line. (This will use Yarn 3, because a copy of Yarn 3 is included inside the Git repo)
Use Visual Studio to open the included typescript-collisions-bug solution.
In VS, open src/app/App.jsx
Wait about 5 minutes, for VS to automatically download TypeScript typings.
Lots of TS errors show up. (I see 347 for this project 🙂)

Sample of the errors:

Please let me know if you're able to reproduce the issue, using the above steps 🙂

@RyanCavanaugh Would you mind taking a look at this, when you have the chance? This bug is currently blocking us from upgrading our JS packages, because when we do, we're swamped with Error messages.

Eli-Black-Work · 2022-02-09T07:27:01Z

@mhegazy , @billti , or @amcasey Would you be the ones to look into this? (Just tagging MS devs who I saw in the original bug report of this: #14565)

Or maybe still @RyanCavanaugh ? 🙂

Sorry to bug. This is blocking us kind of badly.

halm0291 · 2022-03-03T20:10:04Z

Any updates on this? I have tried what people recommended in other issues for previous VS versions with no luck.

Eli-Black-Work · 2022-03-04T02:18:42Z

@halm0291 At the same time that I posted my last comment, I contacted Microsoft with a paid support request to ask about about both this and a related bug: https://developercommunity.visualstudio.com/t/vs2022-esproj-ignores-typeacquisition-setting/1639009

As far as I know, there's hasn't been much movement on this bug. The rep that I contacted said that she was able to reproduce the issue and would talk to the team. Let me follow up with her 🙂

Anyway, the good news is that there's a workaround: Open Visual Studio, go to Tools->Options->Text Editor-> JavaScript/TypeScript -> Project and uncheck "Enable automatic type acquisition (TS 4.1 or later)" (See https://developercommunity.visualstudio.com/t/vs2022-esproj-ignores-typeacquisition-setting/1639009#T-N1673400 for more details.)

Hope that helps! 🙂

minestarks · 2022-03-04T22:29:10Z

@Bosch-Eli-Black I looked into how we're handling that Visual Studio feedback ticket. For your case, the bug we're tracking is actually a problem specific to .esproj projects - we ignore tsconfig.json files completely because they're set to the wrong content type. We have a fix you should see in the next VS update (if not, let me know!).

For any non-VS scenario, that same fix won't apply. It sounds like OP @Spongman is talking about a command-line repro, so their issue probably has a different root cause.

Spongman · 2022-03-05T00:13:46Z

Yes, this issue has nothing to do with Visual Studio. All that's required is the typescript compiler (fetched here via npm).

Eli-Black-Work · 2022-03-07T02:34:28Z

@minestarks Thanks for the update on that Visual Studio ticket – appreciate it! 🙂

Turning type acquisition off in VS is just a workaround for the TypeScript bug that's described in this issue. Ideally, this bug (#36294) would be fixed, too, so that I could still have autocomplete info 😀

minestarks · 2022-03-07T18:48:33Z

Got it. I'm able to repro with @Spongman 's repro steps. There does seem to be a bug as to how we handle junctions.

@Bosch-Eli-Black I think your repro is the victim of multiple different bugs - one, as I mentioned, is fixed in the next update the VS. The second one, where we included a lot of unnecessary typings (which caused all the unnecessary errors) was fixed in #47164 , which is in TS 4.6, which is also bundled in the next update to VS. With these two fixed, I think you won't even hit the third one, which is this bug :)

Eli-Black-Work · 2022-03-08T06:21:46Z

@minestarks Ah, got it! 🙂 Thanks again :)

Eli-Black-Work · 2022-03-24T08:04:06Z

@minestarks Upgrading to VS 17.2 Preview 2 fixed our issue 🙂 Thanks again for your help!

Eli-Black-Work · 2022-05-12T02:57:12Z

By the way, sorry for derailing this bug so badly, @Spongman! I'd thought that the bug I was running into was the same as this one, but I guess not 🙂
