无法解析模块“反应”的路径。 （导入/未解决）

Question

Seems like i am missing something here, it should work without errors but eslint keeps throwing the following:

Unable to resolve path to module 'react'. (import/no-unresolved)

Missing file extension for "react" (import/extensions)

when trying to import React from 'react'

here is some debug info:

package.json

{
  "dependencies": {},
  "devDependencies": {
    "react": "16.3.2",
    "react-dom": "16.3.2",
    "@storybook/addon-actions": "^3.4.2",
    "@storybook/addon-links": "^3.4.2",
    "@storybook/addons": "^3.4.2",
    "@storybook/react": "^3.4.2",
    "babel-core": "^6.26.3",
    "babel-eslint": "^8.2.3",
    "babel-preset-env": "^1.6.1",
    "babel-preset-react": "^6.24.1",
    "babel-runtime": "^6.26.0",
    "eslint": "^4.19.1",
    "eslint-config-airbnb": "^16.1.0",

    "eslint-plugin-jsx-a11y": "^6.0.3",
    "eslint-plugin-react": "^7.7.0"
  }
}

.eslintrc

{
  "parser": "babel-eslint",
  "extends": ["airbnb", "prettier"],
  "env": {
    "browser": true,
    "node": true,
    "es6": true
  }
}

.babelrc

{
  "presets": ["env", "react"]
}

editor : atom v1.26.1

Thanks.

Answer 1

If you're using React Native it may help to add .native.js as an allowed extension in your .eslintrc file.
Also, if you're using Typescript then .ts and .tsx will help too.

"settings": {
  "import/resolver": {
    "node": {
      "extensions": [".ts", ".tsx", ".native.js"]
    }
  }
}

I think it complains because react should be in dependencies :

{
  "dependencies": {
    "react": "16.3.2",
    "react-dom": "16.3.2",
  },
  "devDependencies": {
    "@storybook/addon-actions": "^3.4.2",
    "@storybook/addon-links": "^3.4.2",
    "@storybook/addons": "^3.4.2",
    "@storybook/react": "^3.4.2",
    "babel-core": "^6.26.3",
    "babel-eslint": "^8.2.3",
    "babel-preset-env": "^1.6.1",
    "babel-preset-react": "^6.24.1",
    "babel-runtime": "^6.26.0",
    "eslint": "^4.19.1",
    "eslint-config-airbnb": "^16.1.0",
    "eslint-config-prettier": "^2.9.0",
    "eslint-plugin-import": "^2.11.0",
    "eslint-plugin-jsx-a11y": "^6.0.3",
    "eslint-plugin-react": "^7.7.0"
  }
}

Answer 3

I installed react and react-dom using npm i -E react react-dom trying to install the exact version which didn't install it correctly.

npm i react react-dom -D solved the problem.

Answer 4

Just comment out the import and run. Then again remove the comments. It worked for me.

Answer 5

I have experience with the same problem.

In my case, this error appear because I pull new update from the remote repository and it's bring new dependencies.

To solve this, I just install that dependencies with npm install

Answer 6

我遇到了一些问题，我从项目中删除了 nodo_modules 目录并运行 yarn install / npm install

Answer 7

This also happened to me. In my case, it was because I was running npm version 6, but a team member had installed a new library via npm version 7. Version 7 uses a new version for the lock file format.

Our solution was to make sure everyone was running the same npm version so that our package-lock.json files would be consistent.
