Python似乎正在运行3.6，尽管我的虚拟环境配置为运行3.7

我使用pyenv切换到了python3.7.2。这一点确认如下：

$ python -V
Python 3.7.2

然后，我创建了一个名为venv的虚拟环境，并安装了所有依赖项。当我运行pip列表时，我可以看到这些已经安装

现在使用nosetest运行测试时，我使用以下命令：

nosetests -s -v tests.functional.test_app

测试失败，说明我缺少依赖项。当我检查pip列表时，我可以看到依赖项已经安装。但是，我注意到日志跟踪引用的是Python3.6：

我已经设置了以下pyenv local 3.7.2和pyenv global 3.7.2

---

如何确保在正确的Python版本中运行？

尝试运行哪个nosetests，然后在此处运行python3.7的输出（其中一个nosetests）

/Library/Frameworks/Python.framework/Versions/3.6/bin/nosetests这意味着您需要在Python 3.6环境中安装pip。尝试卸载它，然后在python 3.7环境处于活动状态时再次安装。确定即可。在我这样做之前，是否可以全局安装它？是的，您可以使用sudo pip安装nose，而不激活任何环境。但是，不建议这样做

$ nosetests -s -v tests.functional.test_app
