我刚刚将 @types/jest npm 安装到我的 stenciljs 入门应用程序,现在,当我开始我的项目时,新安装的节点包返回了几个错误。以下是当我转到 npm start
我的项目时它返回的错误:
[ ERROR ] TypeScript: node_modules/@types/jest/index.d.ts:39:30

这是我的 package.json:
...
"dependencies": {
"@stencil/core": "~0.15.2",
"@stencil/router": "~0.3.1",
"imask": "^4.1.5",
"jwt-decode": "^2.2.0",

"puppeteer": "1.8.0",
"workbox-build": "3.4.1"
}
...
这是我的 tsconfig.json:
{
"compilerOptions": {
"allowSyntheticDefaultImports": true,
"allowUnreachableCode": false,
"declaration": false,
"experimentalDecorators": true,
"lib": [
"dom",

"noUnusedParameters": true,
"jsx": "react",
"jsxFactory": "h"
},
"include": [
"src"
],
"exclude": [
"node_modules"
]
}
我已尝试使用新的模板启动应用程序复制错误,但它不是应用程序。此外,尝试删除我的 package-lock.json
并重新安装包以消除任何潜在的冲突。
最佳答案
尝试将 "skipLibCheck": true
添加到 tsconfig.json
以跳过所有声明 (.d.ts) 文件的类型检查。
编辑:这更像是一个“大锤”解决方法,而不是实际修复。正如另一个答案中所提到的,这个问题的发生可能是因为 Jest 类型是为比项目中使用的版本更新的 TypeScript 版本制作的。因此,正确的解决方法是将项目升级到更新的 TS 版本。
