找不到名称“PropertyKey" [英] Cannot find name 'PropertyKey'

问题描述

我正在尝试在一个项目上运行 Webpack，但出现多个错误

I am trying to run Webpack on a project and I am getting multiple errors

node_modules/@types/core-js/index.d.ts
error TS2304: Cannot find name 'PropertyKey'.
...
node_modules/@types/core-js/index.d.ts
error TS2339: Property 'for' does not exist on type 'SymbolConstructor'.

我应该安装所有类型，所以我不确定这些是从哪里来的.我尝试从编译的项目中复制 package.json ，但没有帮助.我错过了什么?

I should have all my typings installed so I am not sure where these are coming from. I tried copying over a package.json from a project that compiles but it didn't help. What am I missing?

我的 tsconfig 看起来像这样

My tsconfig looks like this

{
  "compilerOptions": {
    "target": "es5",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "sourceMap": true,
    "noImplicitAny": false,
    "suppressImplicitAnyIndexErrors": true
  },
  "include": [
    "src/**/*"
  ],
  "exclude": [
    "node_modules",
    "**/*.spec.ts"
  ]
}

推荐答案

我在 0.9.35 使用 @types/core-js 时遇到同样类型的错误

I am getting the same kind of errors with @types/core-js at 0.9.35

可能是别的东西..

编辑

上周回购发生了一些变化.您可以在 github 上阅读问题并通过以下链接查看更改:

我的解决方案是改变

"lib": ["es5", "dom"] 到 "lib": ["es6", "dom"] 在 compilerOptions 对象在我的 tsconfig 文件中.

"lib": ["es5", "dom"] to "lib": ["es6", "dom"] in the compilerOptions object in my tsconfig files.

通过这样做，我使错误消失了，而无需降级到 0.9.35

By doing this I made the errors disappear without downgrading to 0.9.35

注意:你不需要改变目标(我的还是es5)

Note: You dont need to change the target (mine is still es5)
