平台升级后 Bluemix 和 Python / 部署错误
Bluemix and Python / Deploy Error after Platform Upgrade
我在更新的 Bluemix 基础平台下对在 Python 2.7 下开发的 Bluemix 应用程序进行了全新部署（cf push）。部署在 Python PIP 机制中显示错误，这是默认的包安装程序。显然，错误类型可能与缺少 OS 级别（SSL 支持）的 openssl-devel 软件包安装有关。
Error message: ValueError: unsupported hash type md5

当我使用像 https://github.com/cloudfoundry/cf-buildpack-python.git#v1.1.2
这样的旧构建包时，我遇到了同样的问题
来自@chughts 的重要提示：
我怀疑是堆栈让你出局了。我认为 Bluemix 上支持的堆栈现在是 cf_linuxfs2。您将需要使用支持此堆栈的构建包。
我的修复：
使用最新 Python buildpack 的新部署修复了问题：
cf push myapp1 -m 64M -b "https://github.com/cloudfoundry/cf-buildpack-python.git#v1.5.1" -c "python server.py"
崩溃信息已解决。感谢@chughts 的提示和支持。问题已解决。
