运行鼻子测试命令时出现毒素抛出和错误

Question

I created this tox.ini file:

[tox]
envlist = py37

[testenv]
commands = /bin/sh nosetests config_test.test_config_sdk:test_bucket_existing

It throws this error:

$ tox

nosetests config_test.test_config_sdk:test_bucket_existing works when I run it in my terminal though.

Have I done something wrong or is this command not possible in tox?

Answer 1

This is the command you have registered for tox to run:

/bin/sh nosetests config_test.test_config_sdk:test_bucket_existing

Here, nosetests is invoked as a shell script; but that's misleading.
nosetests is an executable python script in your PATH and should be executed directly.

Registering the command as:

nosetests config_test.test_config_sdk:test_bucket_existing

solves the error.
