在Mac OS上导入boto3错误

Question

我正在尝试在我的mac（高sierra 10.13.3）上安装boto3并尝试遵循：https://github.com/boto/boto3。我之前已经使用自制软件安装了python 3，但是当我试图看到pip --version时，我得到了错误。所以我做了

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）为了确保这很好，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，我收到错误

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

我甚至试图改变.bash_profile的路径，但它没有用。思考？

Answer 1

我只需要将名为“bolo”的所有软件包从Python 3.7文件夹复制到Python 2.7文件夹：

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