Question

您好我在这里遇到此问题： init(1)

我也尝试过这个解决方案，但我无法正常工作

我的依赖项：

"dependencies": {
    "@angular/animations": "^4.0.0",
    "@angular/common": "^4.0.0",
    "@angular/compiler": "^4.0.0",
    "@angular/core": "^4.0.0",

    "mobx-remotedev": "^0.2.8",
    "rxjs": "^5.0.1",
    "zone.js": "^0.8.4"
  },
  "devDependencies": {
    "@angular/cli": "1.4.1",
    "@angular/compiler-cli": "^4.0.0",
    "@angular/language-service": "^4.0.0",
    "@types/jasmine": "~2.8.3",
    "@types/jasminewd2": "~2.0.2",
    "@types/node": "^9.4.0",
    "codelyzer": "^4.0.1",
    "jasmine-core": "~2.8.0",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~2.0.0",

    "tslint": "~5.9.1",
    "tslint-config-prettier": "^1.6.0",
    "typescript": "~2.5.3"
  }

tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "types": [
      "node"
    ],
    "lib": [
      "es2017",
      "dom"
    ]
  },
  "exclude": [
    "node_modules",
    "dist"
  ],
  "filesGlob": [
    "./node_modules/@types/**/*.d.ts"
  ]
}

在我尝试的代码中：

import * as fs from 'fs';

export const environment = {
  production: false,
  hmr: true
};

我得到：

ERROR in .../src/environments/environment.hmr.ts (1,21): Cannot find module 'fs'.

任何帮助将不胜感激。感谢

Answer 1

我找到了解决方案：

import { writeFileSync, readFileSync } from 'fs';

现在可以使用

Answer 2

这为我解决了这个问题：

npm install @types/node

Answer 3

你是在Node中运行吗？

为什么不呢 import fs from fs？

同时尝试require并查看内容

Answer 4

我知道我可能迟到了，但我面临着同样的问题。最后，如果您想尝试的话，我得到了解决。在您的tsconfig.json文件中，在“ typeRoots”中添加“ node_modules / @ types / node”，如下所示：

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "typeRoots": [
      "node_modules/@types",
      "node_modules/@types/node"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  }
}

Answer 5

也许你可以像这样在你的 .js 文件中添加一个 module-env 路径

module.paths.push('.\node_modules');

找不到模块＆＃39; fs＆＃39;
