Just pass `--always-unzip` to `easy_install`: … … 64 61 You should end up with a directory having the same name as the zipped egg (complete with `.egg` extension) and containing its uncompressed contents. 65 62 66 Trac also searches for plugins installed in the shared plugins directory ''(since 0.10)'', see TracIni#GlobalConfiguration. This is a convenient way to share the installation of plugins across several but not all environments.63 Trac also searches for globally installed plugins ''(since 0.10)'', see TracIni#GlobalConfiguration. 67 64 68 65 ==== From source ==== … … 70 67 `easy_install` makes installing from source a snap.
