Question

我可以通过运行RubyMine运行部分代码来运行我的测试（右键单击_spec.rb文件并运行）。但是，通过运行“rake spec”我得到一个错误。该表被删除，并且不会在每次测试时重建。我知道它是有目标的，但如果不再重建则不会比如db：test：load，db：test：prepare，db：test：clone_sturcture也行不通。当我运行“rake spec”时我得到了这个错误：

好的，我解决了这个问题。

讨论了here的“libmysql.dll问题”。

问题是mysql 5.0版本。它应该高于5.1。所以，我刚刚将“libmysql.dll”从一个较新的mysql版本改为一个。有效。您需要从开发环境创建适当的转储（db：schema：dump）此命令在项目中创建schema.rb 这个模式由“db：test：prepare”使用，每次执行“rake spec”时都会调用它，然后再进行测试。此schema.rb为空，因此未创建任何表。对我来说听起来很合理。

如果我错了，请纠正我。
