You seem to not be depending on "@angular/core". Typescript
提问by danio900409
I'm trying to run a command at npm start, but I get the message: "You seem to be not dependent on" @angular/core ". This is an error. What could be the reason? As it writes in the console: npm @angular/core -v it gets 5.4.2
我试图在 npm start 上运行一个命令，但我收到消息：“你似乎不依赖于”@angular/core“。这是一个错误。可能是什么原因？正如它在控制台中所写的那样: npm @angular/core -v 它得到 5.4.2

This error occurred in my case when my node_modules folder is empty otherwise it will have bunch of folders inside. I used the "ng link" command to work it out.
当我的 node_modules 文件夹为空时，就会发生此错误，否则里面会有一堆文件夹。我使用“ng link”命令来解决它。
My project name is Pipes, and my command prompt looks like this:
我的项目名称是 Pipes，我的命令提示符如下所示：
Pipes$ npm link
管道 $ npm 链接
And finally you can execute ng serve to check it out
最后你可以执行 ng serve 来检查它

You need to remove ^this, because something its get that version where the others files are effecting due to this version,
你需要删除^这个，因为它得到了那个版本，其他文件由于这个版本而影响，
so always use the specific version in angular.
所以总是在 angular 中使用特定的版本。
