我认为您需要检查托管依赖项。您的依赖方法不匹配。您有library: "0.8.0"之类的内容，这意味着NPM将仅安装该依赖项版本。你也有像library: "^0.8.0"这样的东西，这意味着完全不同的东西。如果您注意到其他输出警告，则说明

npm WARN @angular/core@4.2.6 requires a peer of zone.js@^0.8.4 but none was installed.

你从来没有说过你想要角度核心4.2.6，你说＆＃34; ^ 2.4.8＆＃34;但由于插入符号，NPM安装了最新的兼容主要版本的依赖项。

最后，请注意最后的警告。它表示您尝试添加的库取决于角度核心，其版本与4.0.0兼容。除非您正在处理遗留代码，否则我建议您将所有依赖项更新为更高版本。

未满足的对等依赖关系
