当我跑 ng build我收到以下错误:
ERROR in The Angular Compiler requires TypeScript >=3.4.0 and <3.6.0 but 3.7.4 was found instead.
但在我的
package.json , 我已经定义了 "typescript": "^3.5.3"我在项目中的文件中找到了
3.7.4它没有出现在任何地方，为什么 Angular-CLI 认为这是指定的版本？我正在使用节点 12.13.0。
这是我的全部

最佳答案
npm semver docs解释不同运算符的含义，例如^Caret Ranges允许升级到下一个主要版本。
您可以使用 ~Tilde Ranges而是允许补丁级别更改:
"typescript": "~3.5.3"
或者指定使用 准确版本您应该指定版本号(假定隐含
= 默认值)，例如:"typescript": "3.5.3"
