错误运行tox for airflow

Question

试图促成气流，但不能在Ubuntu 16.0.4上运行并运行。一些事情正在与kerbos进行。

Maybe you forgot to specify a dependency? See also the whitelist_externals envconfig setting.

不知道从哪里即使有这样的开始。我想我已经安装了所有的代码。

脚本scripts/ci/setup_kdc.sh运行在sudo和sudo清除环境变量，所以${KRB5_KTNAME}没有定义。

命令sudo在tox.ini使用，但tox在其虚拟环境中没有找到它（当然它不会 - sudo是不应该被安装在一个VENV系统命令）命令必须是在部分[testenv]在tox.ini列入白名单：

[testenv] 
whitelist_externals = 
    sudo 

这些都是airflow错误，请把他们拉请求或bug报告。
