Unnecessary cyclic dependency on Aerich in 0.16.17

[nckx]

Hi,

Please consider reverting this new cyclic dependency on Aerich.

Tortoise-orm doesn't need Aerich at all: it simply wants to promote its existence. requirements.txt is the wrong place to do so and creates needless distribution headaches.

This is a documentation problem. The same commit also adds an excellent guide. Perhaps promoting it earlier in the README, before the tutorial, would help?

I say perhaps, because people ‘unaware’ of Aerich never bothered to read it.

Thanks!

Yes, cyclic dependency is a bad thing, I will revert that in next release.
