使用"react-scripts": "^4.0.3"樣板創建專案，為了在與typescript專案的反應中包含eslintrc.js檔案，我已經嘗試過eslint --init，它創建了一個默認的eslintrc.js，下面是內容。
在全球擁有 eslint v 7.32.0
eslintrc.js
module.exports = {
env: {
browser: true,
es2021: true,
},
extends: [
'eslint:recommended',
'plugin:react/recommended',
'plugin:@typescript-eslint/recommended',
],
parser: '@typescript-eslint/parser',
parserOptions: {
ecmaFeatures: {
jsx: true,
},
ecmaVersion: 12,
sourceType: 'module',
},
plugins: ['react', '@typescript-eslint'],
rules: {},
};
但是 vs 代碼中的 es lint 任務拋出錯誤
（節點：37609）UnhandledPromiseRejectionWarning：TypeError：無法加載在“.eslintrc.js”中宣告的插件“@typescript-eslint”：未定義的類擴展值不是建構式或為空

現在當我運行下面的命令來安裝丟失的包時
npm i --save-dev @typescript-eslint/eslint-plugin
它在終端中引發錯誤
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!

因此，根據建議嘗試使用選項
npm i --save-dev @typescript-eslint/eslint-plugin --legacy-peer-deps
it was installed successfully but with higher version (5.x) than the @typescript-eslint/parser version and as per mentioned on the eslint-plugin documentation
It is important that you use the same version number for @typescript-eslint/parser and @typescript-eslint/eslint-plugin.
so re install package of similar version
> npm install --save-dev @typescript-eslint/[email protected]
but in vs code it still throw error of
UnhandledPromiseRejectionWarning: TypeError: Failed to load plugin '@typescript-eslint' declared in '.eslintrc.js': Class extends value undefined is not a constructor or null
so I have tried to install
npm install --save-dev @typescript-eslint
but it throw error
npm ERR! code EINVALIDTAGNAME
npm ERR! Invalid tag name "@typescript-eslint": Tags may not have any characters that encodeURIComponent encodes.
also tried by updating es lint latest version 8.0 but it creates another problem.
我知道這是因為我試圖安裝一個不存在的包，但如何解決這個問題？我在這里錯過了什么嗎？
- vscode - v 1.61.1
- ubuntu - v 20.04
uj5u.com熱心網友回復：
檢查eslint 插件命名約定后，發現我必須按照以下語法安裝缺少的@typescript-eslint
npm install --save-dev @typescript-eslint/eslint-plugin
這解決了問題，但未指定反應版本的新錯誤即將出現，因此在“設定”鍵中添加了該錯誤。
