“找不到模塊 'react'”和“找不到 tsconfig.json”

[英]“Cannot find module 'react'” and “tsconfig.json not found”

我正在嘗試使用 TypeScript 使用 NodeJS 和 React 構建基於工作區的應用程序。 我確實在根目錄上配置了package.json並使用工作區 model 來創建服務器和客戶端應用程序。 不幸的是,我遇到了 VsCode 的問題,該問題試圖將tsconfig.json文件解析到根目錄而不是項目文件夾中。

這是我的結構:

project-root
├── .vscode
│   └── settings.json
├── client
│   ├── .eslintrc.js
│   ├── package.json
│   ├── src
│   │   └── App.tsx
│   ├── tsconfig.json
│   └── yarn.lock
├── package.json
└── server
    └── ...

這是上述文件的內容。

好吧,既然我暴露了這個問題,我看到了兩個問題。 他們是這樣的:

  1. 找不到模塊“反應”。

找不到模塊反應

  1. 未找到 tsconfig.json

未找到 tsconfig.json

現在請注意,第二個(tsconfig.json)錯誤顯示的是project-root目錄的路徑,而不是它應該指向的project-root/client目錄的路徑。

那么,我是不是發現了什么問題? 我該如何解決這個問題並讓我的工作區正常工作?

好的,我找到了第二個問題的解決方案,感謝@Daniel,我也可以解決第一個問題。 這是完整的答案:

首先,我做了@Daniel 在他的回答中告訴我的事情,我從我的.vscode/settings.json文件中刪除了這些行:

"eslint.workingDirectories": [
    { "directory": "../server", "changeProcessCWD": true },
    { "directory": "../client", "changeProcessCWD": true }
],

然后,我使用以下內容創建了文件project-root/.eslintrc.js

module.exports = {
    "eslint.workingDirectories": [
      { directory: "./client/", changeProcessCWD: true },
      { directory: "./server/", changeProcessCWD: true },
    ],
};

這樣, Cannot find module 'react'問題就消失了。

現在到tsconfig.json not found問題,我不知道為什么它有效,因為它對我沒有確切的含義,但如果它有效,它就有效。 我將project-root/client/.eslintrc.js parserOption的 parserOption 更改為:

parserOptions: {
    ecmaFeatures: {
        jsx: true,
    },
    ecmaVersion: 2018,
    sourceType: 'module',
    project: './client/tsconfig.json',
},

鑒於已設置changeProcessCWD標志,我不認為我需要更改它。 但它奏效了。 就是這樣了。

感謝所有試圖提供幫助的人。

我只是在類似的設置中遇到了同樣的問題,我解決的方法是在根目錄中創建一個.eslintrc.js並添加以下內容:

module.exports = {
  "eslint.workingDirectories": [
    { directory: "client/", changeProcessCWD: true },
    { directory: "server/", changeProcessCWD: true },
  ],
};

您還應該從.vscode/settings.json中刪除eslint.workingDirectories ,或使用上述代碼更新它。

希望這樣做可以,如果上述步驟不能解決您的問題,您也可以嘗試從project-root/package.json中刪除工作區
