Question

我尝试关注帖子here和there

但是我还远远没有达到这个问题的真实答案。

我在这里还有别的东西吗？

Answer 1

您需要使用the 32-bit version of MYSQL Connector（我认为您使用的是64位）

MYSQL2在Windows上安装很痛苦，但这仅仅是因为依赖关系＆amp;它需要的库本身不是安装的。你几乎就在那里使用MYSQL C-Connector，但你必须卸载＆amp;下载32位版本

Answer 2

没关系。

我弄清楚它出了什么问题。

因为我应该安装32位MySQL连接器版本6.0 版本6.1 ，这是我最初安装的。

我对这里和那里的帖子和论坛非常了解，我忘记在盲目接受其他人的在线解决方案之前先仔细检查我原来的安装。

现在好了。
