WebStorm seemingly having trouble reading tsconfig.json

WebStorm doesn't seem to be reading my tsconfig.json and I can't figure out what's going on.

For example, in one file I'm getting this error:

TS1259: Module '"./node_modules/@types/react/index"' can only be default-imported using the 'esModuleInterop' flag

But as you can see in the config file, esModuleInterop is defined.

Another big issue is it doesn't seem to be resolving path aliases correctly:

TS2307: Cannot find module '@components/Tabs/styled' or its corresponding type declarations.

How many tsconfig.*.json files do you have in your project? WebStorm built-in compiler service uses the nearest tsconfig.json current file is included in for compiling, traversing the folders hierarchy from current folder up to the IDE project root. Your tsconfig.json only includes 2 files - custom.d.ts and next-env.d.ts, note the "files" and "include" sections; so it's not used for other files processing, they are processed either using the other configs or using the default compiler settings


Hi Elena Pogorelova, we just have the one tsconfig.json in the project root. So adding "./**/*" to include should probably fix it?


You c an just remove both the "files" and "include" sections to have all .ts files included

I have faced with same issue. I have 2 "tsconfig*.json" and the following project structure:

The main tsconfig.json is applicable only for  "Source" dicrectory:


  "compilerOptions": {

    "target": "ESNext",
    "module": "CommonJS",
    "moduleResolution": "Node",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "experimentalDecorators": true,

    "strict": true,
    "noUnusedParameters": true,
    "noUnusedLocals": true,
    "noImplicitReturns": true,

    "outDir": "Distributable",
    "declaration": true

  "include": [ "Source/**/*" ]


Another one is requires for "Tests" directory, and also for ESLint:

  "extends": "./tsconfig.json",
  "include": [ "Source/**/*", "Tests/**/*" ]
extends: ./node_modules/@yamato-daiwa/style_guides/ECMAScript.js


  project: "./tsconfig.test.json"

However, the 

TS1259: Module '"path"' can only be default-imported using the 'esModuleInterop' flag

false positive will not disappear event if i'll add "esModuleInterop": true, directory to tsconfilg.test.json.

It works fine for me using same configs and structure
Please share a sample project that reproduces the issue

here is a link to a project that produces the problem on Webstorm. Opening the project on VSCode does not generate the error message: https://github.com/jeromeOlivier/valerie/tree/289521afd75c56e27f0e8ff167ba611b4a486ae7

thank you


Is it backend/server.ts that reproduces the issue? This file is not included in any tsconfig.json so the default settings are used for its processing;you will face the same issue if you run tsc in terminal:

>tsc backend/server.ts
backend/server.ts:1:8 - error TS1259: Module '"C:/downloads/valerie/node_modules/@types/express/index"' can only be default-imported using the 'esModuleInterop' fla

1 import express from "express";

    136 export = e;
    This module is declared with 'export =', and can only be used with a default import when using the 'esModuleInterop' flag.
