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的输入，因此我不确定这些输入来自何处.我尝试从已编译的项目中复制package.json，但无济于事.我想念什么?

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

在0.9.35，@ types/core-js出现了同样的错误

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

可能是其他东西.

上周回购交易发生了一些变化.您可以在github上阅读该问题，并通过以下链接查看更改:

There has been some changes on the repo last week. You can read the issue on github and see the changes via these links:

我的解决方案是改变

"lib": ["es5", "dom"]到"lib": ["es6", "dom"].

这样做，我使错误消失而不降级到0.9.35

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

注意:您不需要更改目标(我的仍然是es5)

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