未找到模块：zipline 导入

Question

从行获取以下堆栈跟踪：

zipline/zipline/__init__.py", line 17, in <module>
    import numpy as np
ImportError: No module named 'numpy'

但是，当我检查pip list

pip list | grep numpy
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
numpy             1.16.6

这一切都发生在我克隆到Quantopian/Zipline Github Repo 之后。 我在 github 上打开了一个 issue，在此编辑之后，我将搜索 SO 以查找我错过的任何明显内容。

环境

WSL Ubunut 子系统

Pyhon 3.5.5

Answer 1

问题是由于multiple versions of python 的存在而出现的。在zipline/zipline repo 中使用python -m pip install <packages> 命令，我能够在python shell 中成功执行import zipline
