After almost 3 years of work and more than 100 pull requests, we are proud to announce the Beta-stage support for running Galaxy under Python 3. Lint, unit, API, framework, integration and Selenium tests all pass, time for you to give it a try and report any bug you find!
从 release_19.05 起，Galaxy 对 Python 3 提供了比较好的支持（Galaxy is currently supported on Python 2.7 and >=3.5），在本教程我们将以 release_19.09 最新版本的 Galaxy 为基础，进行一系列安装、部署和简单开发说明。
Galaxy is currently supported on Python 2.7 and >=3.5 . To run Galaxy, please install a supported Python version. If a supported version is already installed but is not your default, https://galaxyproject.org/admin/python/ contains instructions on how to force Galaxy to use a different version.

注意与提示：
使用 Python 3 安装 Galaxy，需要保证 SSL 模块正常可用。
如果在第一次启动 Galaxy 过程中出现如下报错，参考后面的方法进行解决。
