Streisand: Streisand errors when setting up server: "boto3 required for this module"

[Blubberx]

Expected behavior:

I'm trying to set up a Streisand server on AWS, and have followed the instructions, but keep getting errors just after the "Streisand will now set up your server" message.

Actual Behavior:

Error message "boto3 required for this module. to retry, use: --limit @/Users/remy/streisand/playbooks/amazon.retry"

Steps to Reproduce:

1. Run Streisand, choose Amazon and default settings and AWS access keys
2. Get error message "boto3 required for this module. to retry, use: --limit @/Users/remy/streisand/playbooks/amazon.retry"
3. Run "./streisand --limit @/Users/user/streisand/playbooks/amazon.retry"
4. Get same error.

I have installed boto using the sudo pip install boto command. If I run "sudo pip install boto3" I get exceptions uninstalling six-1.4.1.

Streisand will now set up your server. This process usually takes around ten minutes. Press Enter to begin setup...

Python environments can get really messed up over time. (Ask me how I know.) I think you might have modules with conflicting dependencies.

The easiest thing to do (well, easiest for me!) is suggest you install the dependencies in a virtualenv. See https://github.com/nopdotcom/streisand/blob/builder-scripts/util/venv-dependencies.sh (but be aware it's not perfect yet). If you speak virtualenv, start reading at around line 88.

Another alternative is to set up a cloud machine somewhere from scratch, then install just the Streisand dependencies.

@Blubberx I found a workaround that appears to work, could you give the following command a try:

sudo pip install boto3 --ignore-installed six and let me know if that resolves your issue?

[Blubberx]

@alimakki Many thanks, this appears to have done the trick!

I had tried sudo pip install boto3 --please just do it but this is even better ;-)

@nopdotcom Thanks also for taking the trouble to reply.

@Blubberx glad I could help.
