Cannot find module '??' or its corresponding type declarations.
This happens when a dependency's package.json looks like this:
"exports": {
".": {
"node": {
"types": "./dist/index.d.ts",
"module": "./dist/index.module.js",
"require": "./dist/index.js",
"import": "./dist/index.mjs"
},
"browser": {
"types": "./dist/index.d.ts",
"import": "./dist/index.module.js",
"require": "./dist/index.js"
},
"default": "./dist/index.module.js",
},
"./package.json": "./package.json"
},
if you add "types": "./dist/index.d.ts" after the default the issue is fixed. This does not match regular typescript.
We really need a fully cloneable repo in order to diagnose these, can you please provide one? Thanks!
I think I ran into a similar issue. I created a minimal repo here: https://github.com/prochri/typescript-go-test
The imports work fine with JS tsc, but error on Go tsc:
src/file.ts:3:28 - error TS2307: Cannot find module 'three/examples/jsm/loaders/GLTFLoader' or its corresponding type declarations.
3 import { GLTFLoader } from "three/examples/jsm/loaders/GLTFLoader"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
src/file.ts:4:24 - error TS2307: Cannot find module 'swiper' or its corresponding type declarations.
4 import { Swiper } from "swiper"
~~~~~~~~
The exports field in package.json of threejs, for example, looks like this:
"exports": {
".": {
"import": "./build/three.module.js",
"require": "./build/three.cjs"
},
"./examples/fonts/*": "./examples/fonts/*",
"./examples/jsm/*": "./examples/jsm/*",
"./addons": "./examples/jsm/Addons.js",
"./addons/*": "./examples/jsm/*",
"./src/*": "./src/*",
"./webgpu": "./build/three.webgpu.js",
"./tsl": "./build/three.tsl.js"
},
I ran into a similar issue with "@descope/nextjs-sdk" in a projecrt. TSGO is unable to resolve the imports field when the imported packages package.json export look like this:
"exports": {
".": {
"import": {
"types": "./dist/types/index.d.ts",
"default": "./dist/esm/index.js"
},
"require": "./dist/cjs/index.js"
},
However when modded to this it is able to resolve modules and types:
"exports": {
".": {
"types": "./dist/types/index.d.ts",
"default": "./dist/esm/index.js""
},
Same is happening in vite for me:
test.ts:3:10 - error TS2305: Module '"node_modules/.pnpm/[email protected]/node_modules/vite/index"' has no exported member 'searchForWorkspaceRoot'.
import { searchForWorkspaceRoot } from "vite";
While in the editor the non tsgo version uses
"node_modules/.pnpm/[email protected]/node_modules/vite/dist/node/index" instead of '"node_modules/.pnpm/[email protected]/node_modules/vite/index"'.
Looking at the vite package.json:

I had to add "types": "./dist/node/index.d.ts", just AFTER "import": "./dist/node/index.js", and BEFORE "require": "./index.cjs" at exports["./"].
So the following snippet worked for me to remove the error (I didn't test building, just type checking):
"types": "./dist/node/index.d.ts",
"exports": {
".": {
"module-sync": "./dist/node/index.js",
"import": "./dist/node/index.js",
"types": "./dist/node/index.d.ts", // ADDED THIS
"require": "./index.cjs"
},
"./client": {
"types": "./client.d.ts"
},
"./module-runner": "./dist/node/module-runner.js",
"./dist/client/*": "./dist/client/*",
"./types/*": {
"types": "./types/*"
},
"./types/internal/*": null,
"./package.json": "./package.json"
},
I found same error with rolldown-vite
Work around: pnpm patch https://github.com/mizchi/play-rolldown-vite-tsgo/blob/main/patches/rolldown-vite.patch
I had a similar issue when trying to import a file not defined in the package.json exports definition
https://github.com/MaintainX/yarn-plugin-workspace-lockfile/blob/8ae38c8799320b043f0db5cd1be3d81048711564/src/index.ts#L1-L14
// InstallOptions is not exported from `@yarnpkg/core` so just go get it from its definition
import { InstallOptions } from "@yarnpkg/core/lib/Project";
This works fine in normal typescript
@mizchi's repro in https://github.com/microsoft/typescript-go/issues/518#issuecomment-2924630799 was the same as #904, now fixed.
In @prochri's repro in https://github.com/microsoft/typescript-go/issues/518#issuecomment-2794926185, things are behaving "as expected" because that repo is attempting to use the old/bad node10 module resolution mode. Flip the repro to nodenext, bundler, etc, and even TS 5.8 complains.
The same applies to @Cellule's repro above: https://github.com/microsoft/typescript-go/issues/518#issuecomment-3009126440
That's also using the old node10 resolution. Flipping it to nodenext shows the same exact problem in 5.8.
npx tsc
src/index.ts:12:32 - error TS2307: Cannot find module '@yarnpkg/core/lib/Project' or its corresponding type declarations.
12 import { InstallOptions } from "@yarnpkg/core/lib/Project";
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Found 1 error in src/index.ts:12
So, these are all just down to "we are not bringing the very-not-recommended node10 resolution forward".
followed the instructions here but met with a wall of failed imports
It's a nextJS app , but have same issue with NESTJS backend..
Using cursor

You can see there are errors in tsconfig.json; baseUrl has been removed. See https://github.com/microsoft/TypeScript/issues/62508#issuecomment-3348649259.
