Python 似乎是运行ning 3.6，即使我的虚拟环境配置为运行 3.7

Question

我使用 pyenv 切换到 Python 3.7.2。下面证实了这一点：

$ 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我所有的依赖项。当我运行 pip list.

时，我可以看到这些已经安装

当我现在运行我使用 nosetest 进行测试时，我使用这个命令：

nosetests -s -v tests.functional.test_app

测试失败，说明我缺少依赖项。当我检查 pip list 时，我可以看到依赖项已经安装。但是我确实注意到日志跟踪引用了 Python3.6:

$ nosetests -s -v tests.functional.test_app
Failure: ModuleNotFoundError (No module named 'botocore') ... ERROR

我设置了以下 pyenv local 3.7.2 和 pyenv global 3.7.2。

如何确保我运行正在使用正确的 Python 版本？

尝试 which nosetests 然后运行 python3.7 output_of_which_nosetests_here
