我正在努力解决 VSCode 中的“错误”：

Argument for '--jsx' option must be: 'preserve', 'react-native', 'react'

因此，当value 似乎有效时，react-scripts (create-react-app) 会自动将jsxkey设置为react-jsxvalue react。

实际上，代码运行良好并显示了我想要的页面，但是 IDE 将所有内容都强调为错误，并说：

Cannot use JSX unless the '--jsx' flag is provided.

这是我的 tsconfig.json ：

{
  "compilerOptions": {
    "target": "es5",
    "lib": [
      "dom",
      "dom.iterable",
      "esnext"
    ],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noFallthroughCasesInSwitch": true,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react-jsx"
  },
  "include": [
    "src"
  ]
} …

我已经四处寻找解决这个问题的方法了.所有这些都建议添加"jsx": "react"到您的tsconfig.json文件.我做了什么.另外一个是补充"include: []",我也做了.但是,当我尝试编辑.tsx文件时,我仍然收到错误.下面是我的tsconfig文件.

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "allowJs": true,
        "checkJs": false,
        "jsx": "react",
        "outDir": "./build",
        "rootDir": "./lib",
        "removeComments": true,
        "noEmit": true,
        "pretty": true,
        "skipLibCheck": true,
        "strict": true,
        "moduleResolution": "node",
        "esModuleInterop": true
    },
    "include": [
        "./lib/**/*"
    ],
    "exclude": [
        "node_modules"
    ]
}

任何的意见都将会有帮助.我正在使用babel 7来编译env,react和typescript预设的所有代码.如果你们需要更多文件来帮助调试这个,请告诉我.

我正在学习 firebase 云函数，在我的index.ts文件夹中，我在导入下突出显示了错误消息

import * as functions from "firebase-functions";

// Start writing Firebase Functions
// https://firebase.google.com/docs/functions/typescript

export const helloWorld = functions.https.onRequest((request, response) => {
  functions.logger.info("Hello logs!", { structuredData: true });
  response.send("Hello from Firebase!");
});
