Hi,

There is more to installing Calendar Server than just the pip dependencies. Specifically, there are various C-based dependencies you need as well (such as memcache, which appears to be missing in your case).

Unfortunately the task of installing Calendar Server is kind of complicated, and varies by platform. You can try using "bin/package <dest directory>" to attempt to install Calendar Server and all its dependencies into the specified directory. The specific way you start the service also matters, in particular the invoking environment. The 'package' script emits an environment.sh file that should be sourced by the shell that starts CalendarServer.

... and now that I think of it, everything I just said applies to trunk (at least v8 and newer), but possibly not v7... Give it a try and if you're still stuck tomorrow I'll dig deeper :)

(The easiest way to use the service is in 'develop' mode which takes care of all this stuff for you, where you use bin/develop and then bin/run, but that is not really 'installation' per se)

Hello,

I have install the calendarserver dependence throw pip with this command,

pip install -r requirements-stable.txt
