Question

所以我有一个基本的Python类模块，在其中导入了箭头库。

#!/usr/bin/env python3

import arrow

class SomeClass:
    def __init__(self):
        print("hello")

我有一个正在使用pytest some_test_file.py调用的测试文件，该文件导入了SomeClass模块。我得到E ModuleNotFoundError: No module named 'arrow'。

我做了pip install arrow和asdf reshim python和asdf reshim python 3.7.2，但仍然无法正常工作。

您可能使用了错误的python。就像您可以在下面看到的那样：

pako@b00s:~$ pyenv shell 3.7.0
pako@b00s:~$ pip install arrow

asdf python未拾取箭头库
