[IIAB] install problems

[Tony Anderson]

Hi,

As I mentioned the gcc problem has been solved by installing lzma built 
on the Ubuntu system. I ran the test and it ran perfectly. Also the 
installs dependent on lzma accepted it.

The reason for the install of the packages is that the internet-in-a-box 
assumes the install occurs online. I downloaded the corresponding tar or 
zip files and installed each separately.

As a result, I have the latest of each package.

SQLalchemy is 0.82, Flask-SQLalchemy is 1.0.

Since both of these are Python packages, I can't see how this import 
error occurs.

Ultimately, the way I got off the beaten path is not have being online.
What I could do now is use yum with the CentOS repository to install pip 
and retry the install. However, as you mentioned, the state of the 
server is unknown due to all the installs and re-installs.

It looks like several of these packages are based on Django. Was there a 
particular reason you chose to go with Flask instead of Django?

When I get back home (end of September), I plan to purchase another box 
and use it to test the install process from scratch. It may be that I 
won't be able to get iiab working until then.

Thanks for your help and advice.

Yours,

Tony
