Angular应用运行npm install时出错-无法解决依赖

Question

我有一个Angular 9 (* UPDATE，这意味着Angular 11)，它是在Ubuntu和Mac机器上开发的。下面的命令可以正常工作:

npm install

所以现在我需要将它部署到Linux Centos 7服务器。所以我把它码头化了。当Dockerfile想要执行npm install时，它会得到以下错误:

Ay想法?

Answer 1

您说您的应用程序是用ng 9编写的，但有一些行错误，如npm ERR! Found: @angular/common@11.0.9和angular-datatables@"^10.0.0"，其中ng版本为11。这可能是问题所在，因为angular-datatable 10.0.0版本和angular 11之间存在依赖关系。修复这个问题，它就可以正常工作了
