python - Mac OS 上导入 boto3 错误

Question

我正在尝试在我的 mac(high Sierra 10.13.3)上安装 boto3 并尝试遵循:https://github.com/boto/boto3 。我之前已经使用 homebrew 安装了 python 3，但是当我尝试查看 pip --version 时，出现错误。所以，我做到了

1)修改.bash_profile添加

alias pip=pip3

2)验证

$ pip --version
pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)

3)

$ pip install boto3

4)只是为了确保这没问题，我跑了

$ pip3 install boto3
Requirement already satisfied: boto3 in /usr/local/lib/python3.6/site-packages

5) 但是，现在当我在 Idle 中运行 import boto3 时，出现错误

import boto3
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import boto3
ModuleNotFoundError: No module named 'boto3'

我什至尝试更改.bash_profile中的路径，但它不起作用。想法？

对我来说，只需将名称中包含“bolo”的所有包从 Python 3.7 文件夹复制到 Python 2.7 文件夹即可:

/usr/local/lib/python3.7/site-packages $ sudo cp -R boto* /Library/Python/2.7/site-packages/.
