我用——template typescript创建了一个新的React Native项目
我删除了作为样板的一部分的模板目录。
然后我继续添加ESLint:
module.exports = {
parser: "@typescript-eslint/parser",
plugins: ["@typescript-eslint"],
extends: ["airbnb-typescript-prettier"]
};
然而,当我打开babel.config.js时,我得到这个错误
解析错误:"parserOptions. "已经为@typescript-eslint/parser设置了Project "。
该文件与您的项目配置不匹配:/Users/Dan/site/babel.config.js。
该文件必须包含在至少一个提供的项目中。eslint
对我来说,这个问题发生在parserOptions中列出的项目时。项目扩展了基本的tsconfig。Json,它排除了这个文件。
删除extends: './tsconfig. txt。来自parserOptions中列出的项目的json。项目或从基本配置中删除exclude可以修复该问题。但是这种解决方法并不实用,因为我们需要扩展基本配置。
重写属性exclude将非常有帮助。
tsconfig.spec.json
{
"extends": "./tsconfig.json",
"compilerOptions": {
"outDir": "./dist",
"types": ["jest"]
},
"include": ["**/*.spec.ts"],
"exclude": [""]
}
在我的ESLint配置中,我有以下配置:
.eslintrc.js
module.exports = {
root: true,
env: {
node: true,
},
globals: {
Promise: "readonly"
},
parser: "@typescript-eslint/parser",
parserOptions: {
sourceType: "module",
tsconfigRootDir: __dirname,
project: ["./tsconfig.eslint.json"],
},
plugins: ["@typescript-eslint"],
extends: [
"eslint:recommended",
"prettier/@typescript-eslint",
"plugin:@typescript-eslint/recommended",
"plugin:@typescript-eslint/recommended-requiring-type-checking",
],
}
更新
修复的关键部分是:
parser: "@typescript-eslint/parser"
这:
parserOptions: {
sourceType: "module",
tsconfigRootDir: __dirname,
project: ["./tsconfig.eslint.json"], // could be tsconfig.json too
}
不要忘记在tsconfig.json的include数组中包含该文件或文件的目录。
简单地通过在.eslintrc.js中添加ignorePatterns选项来指示eslint忽略它们:
module.exports = {
root: true,
parser: '@typescript-eslint/parser',
parserOptions: {
project: './tsconfig.json',
},
ignorePatterns: ["babel.config.js"],
...
由于检测您的项目配置文件没有多大价值,您可以安全地忽略它们。
另外,我不会让它们成为你的tsconfig的一部分。Json或创建一个特殊的tsconfig.eslint.json文件,仅用于检测目的。
Despite assurances that typescript definitely, absolutely, never caches anything, I suspected this was a caching issue after, when getting annoyed at incessant typescript errors while debugging and developing a feature, I modified my tsconfig.json to exclude my src directory temporarily. Upon reverting the change, and restarting my typescript server running through WebpackDevServer, I had this error, and got rid of it by doing yarn cache clean to clear my yarn cache, as well as rm -rf node_modules to delete my node modules folder. Then I re installed my packages with yarn and when I ran my devserver again, typescript/tslint no longer showed this error.
