Question

我在Angular-Meteor项目中使用Meteor 1.3.x-1.5.x作为服务器，并通过Angular CLI构建了Web客户端。直到Meteor 1.6，我已经能够使用通过符号链接共享的单个node_modules目录来减少客户端和服务器之间的许多共享依赖关系的大小并轻松保持同步，遵循Angular的示例 - 流星启动器应用程序。

但是，从服务器目录根目录中出现的新package-lock.json文件开始，Meteor 1.6似乎在node_modules中安装了自己的依赖项，包括许多@angular/*依赖项，这导致由于多个冲突的软件包安装，我得到以下错误。有什么建议吗？

```

This likely means you have several @ngtools/webpack packages installed. You can check this with `npm ls @ngtools/webpack`, and then remove the extra copies.

我能够通过以下方式解决这个问题：

全局更新至node@8.8.1以匹配与Meteor 1.6捆绑的版本
更新到Meteor 1.6
将符号链接添加到根package.json＆amp; Meteor目录中的package-lock.json
删除node_modules文件夹并在根npm install上执行package.json
避免对meteor npm install的任何调用（我在postinstall npm脚本中一直在进行调用以构建bcrypt二进制文件）

在Meteor 1.6服务器和服务器之间共享`node_modules`。 Angular CLI客户端Angular-Meteor子项目？
