被抛弃的问题：为什么'；npm安装'；删除我的包？

命令是

npm install--save file saver

，它返回以下内容：

npm WARN The package enzyme is included as both a dev and production dependency.
npm WARN The package gulp-util is included as both a dev and production dependency.
npm WARN The package react-addons-test-utils is included as both a dev and production dependency.

+file-saver@1.3.3
added 1 package and removed 15 packages in 6.536s

我知道删除的两个包是

react-google-recaptcha

和

react-async-script

。另外，我没有使用npm的公共注册表。

已删除的包是否包含在

package.json

中？@EdmundReed是的。您使用的npm版本是什么？
