Boto3: import boto3 error

[jiashenC]

Import boto3 always gives error. When I tries to import boto3 for the first time, Python gives error

Traceback (most recent call last):

If I try to import again, the error becomes

I have tried to use old version

boto3==1.4.4
botocore==1.5.95

And I also tried to upgrade to latest version

boto3==1.5.6
botocore==1.8.20

both of these give the same error.

AWS version that I use is

awscli==1.14.16
awsebcli==3.12.1

I have also posted this issue on StackOverflow. Still no luck of fixing this.

I would recommend trying to completely uninstall botocore / boto3 and do a re-install. Something in your installation is off. I would also recommend using a virtualenv so that these sorts of issues can be isolated and easily resolved.

[jiashenC]

I try to use virtualenv and install boto3 from scratch, but it still does not work. I don't know if it is installation issue. I try to run import boto3 in Python command line and it works fine. It only fails if I try to run a program containing import boto3.

[maxpearl]

How did you install boto3? Did you install via pip? What's your OS?

[jiashenC]

Yes, I install via pip. My Python version is 2.7.10 and I am using MacOS. OS version is macOS 10.13.2.

[abhinavpanse]

My python is 3.6.2

Exactly this is the error

[jiashenC]

This issue is very weird.

Disabling MacOS rootless feature only solves the issue temporarily, and then it fails again.

I tried to install boto3 from source in virtualenv and it succeeded once. However, after I try to recreate same environment with same approach, it fails again.

[abhinavpanse]

exactly...
It works sometimes, but every time else it doesn't.

[jiashenC]

Please look at this post

I think our mistake is to put our file named as email.py and Python cannot pick up the correct module as pointed by the post.

It is not related to package installation. Just rename the file.

Looks like @jiashenC figured it out.
