import boto3 error on Mac OS

Question

I'm trying to install boto3 on my mac (high sierra 10.13.3) and tried to follow : https://github.com/boto/boto3. I had already installed python 3 using homebrew before, but when I tried to see pip --version, I get error. So, I did

1) modify .bash_profile to add

alias pip=pip3

2) verify

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

3)

$ pip install boto3

4) just to make sure this was fine, I ran

$ pip3 install boto3

5) but, now when I ran import boto3 in Idle, I get error

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

I even tried to change path in .bash_profile, but it did not work. Thoughts?

Answer 1

For those seeing this in 2023, check ImportError after successful pip installation, as noted by @Ankur Jyoti Phukan. For example, if you use also brew for package management, both the python3 and boto3 should be installed with boto3. When python3 already installed, for boto3 either:

python3 -m pip install boto3

or:

brew install python-boto3

Answer 2

It worked for me to just copy all of packages with "bolo" in the name from the Python 3.7 folder to the Python 2.7 folder:

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