“导入错误：没有名为 boto3 的模块”在 Mac 上

Question

I am trying a deployment script, which will need to import boto3, when I run the script, it give me error message:

ImportError: No module named boto3

then I ran:

pip install boto3

it returns:

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)

I ran pip3 install boto3 , still it gave the same output as above.

then I ran the deployment script, the same errors with complaining

ImportError: No module named boto3

Any ideas where goes wrong?

I'm using mac 10.14.6 version.

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)

Make sure that /usr/local/lib/python3.7/site-packages and /Users/xiaoyiliu/Library/Python/3.7/lib/python/site-packages are in the path.

Use the below code to temporarily append it to the path.:

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

Make sure you have installed your package with the pip associated with a particular python, use:

python -m pip install <pkg>

instead of:

pip install <pkg>
