我创造了这个tox.ini文件：
[tox]
envlist = py37
[testenv]
commands = /bin/sh nosetests config_test.test_config_sdk:test_bucket_existing
它抛出这个错误：
$ tox

当我在终端上运行它，虽然nosetests config_test.test_config_sdk:test_bucket_existing工作。
难道我做错了什么事，或者这是命令不可能在TOX？
这是您注册tox运行命令：
/bin/sh nosetests config_test.test_config_sdk:test_bucket_existing
在这里，nosetests被调用的shell脚本;但是这是误导。
nosetests是在你的PATH一个可执行的Python脚本，应直接执行。
注册的命令：
nosetests config_test.test_config_sdk:test_bucket_existing
解决了错误。
