Question

运行ng build时出现以下错误：

Angular编译器中的错误需要TypeScript> = 3.4.0和<3.6.0，但是找到了3.7.4。

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

我在项目中的文件3.7.4中找到了一个文件，但是找不到它，所以Angular-CLI为什么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解释了不同运算符的含义，例如^Caret Ranges允许升级到下一个主要版本。

您可以改用~Tilde Ranges来更改补丁程序级别：

"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"
