I am on PHPStorm 2017.2.4.
When I search for plugins, I get Pug (ex-Jade), but it only shows version 172.2656.13, which based on this page: https://plugins.jetbrains.com/plugin/7094-pug-ex-jade-? indicates that it was released on Jun 2, 2017. However, they have a build for October of this year (173.3188.31), but I cannot install it.
When I attempt to download the ZIP and install manually, PHPStorm indicates: "Plugin 'Pug (ex-Jade) is incompatible with this installation".
