“导入错误：没有名为 boto3 的模块”在 Mac 上

Question

我正在尝试一个部署脚本，该脚本需要导入 boto3，当我运行该脚本时，它给了我错误消息：

ImportError: No module named boto3

然后我跑了：

pip install boto3

它返回：

Requirement already satisfied: boto3 in /usr/local/lib/python3.7/site-packages (1.9.228)
Requirement already satisfied: jmespath<1.0.0,>=0.7.1 in /Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages (from boto3) (0.9.4)
Requirement already satisfied: s3transfer<0.3.0,>=0.2.0 in /Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages (from boto3) (0.2.1)

Requirement already satisfied: urllib3<1.26,>=1.20; python_version >= "3.4" in /Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages (from botocore<1.13.0,>=1.12.228->boto3) (1.25.3)

我跑了pip3 install boto3，它仍然给出与上面相同的输出。

然后我运行了部署脚本，抱怨同样的错误

ImportError: No module named boto3

任何想法哪里出了问题？

我使用的是 mac 10.14.6 版本。

已满足要求： /usr/local/lib/python3.7/site-packages (1.9.228) 中的 boto3 已满足要求： /Users/xiaoyiliu/Library/Python/ 中的 jmespath<1.0.0,>=0.7.1 3.7/lib/python/site-packages（来自 boto3）（0.9.4）

确保/usr/local/lib/python3.7/site-packages和/Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages位于路径中。

使用以下代码将temporarily其附加到路径：

import sys
print(sys.path)
sys.path.append('/usr/local/lib/python3.7/site-packages')
sys.path.append('/Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages')
print(sys.path)

import boto3
