Deprecated in mongoose about m-mall-admin HOT 9 CLOSED

是不是mongoose版本不对？我看了您的webpack的mongoose版本是4.6.0的。需要安装旧版本mongodb对吗？

from m-mall-admin.

@angelfreedomv 有可能，最好按照 package.json 版本来。另外我本地 mongodb-3.2.7、redis-3.2.3。

你本地测试是windows还是mac os系统？我看了一下本地的mongodb是3.4.9版本，要降级版本对吧。

@angelfreedomv mac

我找到了 3.2.7版本，还是不行，老是出这样的问题，是不是要改成openUri() ？。

解决了，刚才网络问题少装了依赖

我使用了以下步骤解决了此问题：
npm remove mongoose
npm install [email protected] --save
