在Pycharm下运行行为不起作用，但在bash命令行下运行相同行为

Question

我有一个很烦人的问题，我无法解释（也无法解决：）在Pycharm（版本2018.1，内部版本＃PY-181.4203.547）下运行行为测试。

我已经定义了如下的Behave运行配置：

除了行为版本（即1.2.6）之外，virtualenv中没有其他特殊内容：

(sanitycheck)$ pip freeze | grep behave
behave==1.2.6

如果我从pycharm运行测试以启动上述配置，则会收到错误消息：

也就是有关重复步骤定义的问题。但是，该步骤没有重复，实际上，如果我按如下所示从命令行运行上述测试，那么它将起作用。

(sanitycheck)$ behave tests/features/TS04_pepflows/026_pep2cbv2_httpsnotifications.feature
...
0 features passed, 1 failed, 0 skipped
0 scenarios passed, 1 failed, 0 skipped
12 steps passed, 1 failed, 3 skipped, 0 undefined
Took 0m21.965s

（预计测试将失败，“ 1失败”是可以的）

此外，如果我从bash命令行运行Pycharm运行的相同命令（以上日志中的第一行：/home/fermin/src/virtualenvs/sanitycheck/bin/python2.7 /data/apps/pycharm-2017.3.4/helpers/pycharm/behave_runner.py），则它可以工作（尽管在这种情况下，它不仅执行.feature，而且还执行所有测试）我想要）。

有人遇到过同样的情况吗？关于为什么它可以从bash命令行运行但在Pycharm下不起作用的任何想法吗？如何解决这个问题？

谢谢！
