Deprecated in mongoose

[angelfreedomv]

I found a problem:
[2017-09-21 12:04:47.191] [ERROR] console - (node:8808) DeprecationWarning: open() is deprecated in mongoose >= 4.11.0, use openUri() instead, or set the useMongoClient option if using connect() or createConnection(). See http://mongoosejs.com/docs/connections.html#use-mongo-client.

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？

[skyvow]

@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。

[angelfreedomv]

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

[angelfreedomv]

好的 谢谢了 我降级版本试试

mongodb 3.2 windows版本在网上不好找了啊

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 mongoose@4.10.8 --save
