Angular 看到错误的 Typescript 版本

Question

当我运行 ng build 我得到以下错误：

ERROR in The Angular Compiler requires TypeScript >=3.4.0 and <3.6.0 but 3.7.4 was found instead.

但是在我的package.json中，我定义了"typescript": "^3.5.3"

我在项目的文件中查找了 3.7.4 但它没有出现在任何地方所以为什么 Angular-CLI 认为这是指定的版本？

我正在使用节点 12.13.0。

这是我的完整 package.json:

npm semver docs explains the meanings of the different operators, e.g. ^Caret Ranges 允许升级到下一个主要版本。

您可以改用 ~Tilde Ranges 来允许补丁级别更改：

"typescript": "~3.5.3"

或者要指定使用确切版本，您应该指定版本号（假定默认为=），例如：

"typescript": "3.5.3"
