Angular：为什么在新的npm安装之后，package-lock.json的软件包版本会高于package.json？
我的理解是，npm（早在2017年？）决定更新package.json中版本高于package-lock.json中版本的任何包 我观察到我的项目似乎自发地升级了我不想升级的包，这是一个有趣的现象 例如，我最近切换到Angular 9，我开始遇到一些奇怪的错误，比如： 无法绑定到“ngIf”，因为它不是“button”的已知属性 我没有运气（也就是说，我在StackBlitz上没有得到同样的错误：它似乎在那里工作得很好）。因为，我决定在我的本地项目（github版本）上降级我的core js版本，以尽可能接近stack blitz的工作内容 这就是我困惑的地方。我删除了node_模块和package-lock.json，并将我的package.json更改为以下内容：Angular：为什么在新的npm安装之后，package-lock.json的软件包版本会高于package.json？,angular,npm,Angular,Npm,我的理解是，npm（早在2017年？）决定更新package.json中版本高于package-lock.json中版本的任何包 我观察到我的项目似乎自发地升级了我不想升级的包，这是一个有趣的现象 例如，我最近切换到Angular 9，我开始遇到一些奇怪的错误，比如： 无法绑定到“ngIf”，因为它不是“button”的已知属性 我没有运气（也就是说，我在StackBlitz上没有得到同样的错误：它似乎在那里工作得很好）。因为，我决定在我的本地项目（github版本）上降级我的core js版本

npm install在package-lock.json中似乎有许多不同版本的core js，其中一些版本高于v3.0.0，尽管我在package.json中指定了
“core js”：“^2.0.0”
