How to overwrite Django app to Pythonanywhere?

After the second time deploying the Django app to Pythonanywhere, (I re-edited and overwritten in VS code and did git push) I got the following error.
WARNING: Package(s) not found: django
Traceback (most recent call last):
File "/home/hogehohe/.local/bin/pa_autoconfigure_django.py", line 47, in <module>

The command is
$ pa_autoconfigure_django.py https://github.com/[user_name]/[project_name].git --nuke
The first deployment succeeded but the second one is not. I don't know the cause and how to overwrite it...

You need to have a requirements.txt file in your project that specifies the packages that you need for your app. I'm guessing that your first project had one that included django and that your second one does not.

Installing Google Cloud SDK throwing error in install.py when using install.bat

I am trying to install google cloud SDK using install.bat. I have tried downloading the bundled pythons versions 275 and current version 276, they both fail at the same spot. It is able to find python in the platform/bundledpython folder so that is not the issue. I have also tried the suggestions online including making sure that the "Find" command works on a command prompt. Any help appreciated.
The latest available version is: 276.0.0

I just had the same problem trying to install the latest Google Cloud SDK (276.0.0). The Windows setup was stuck on "Installing components".
Looking at the process list with Process Explorer I could see it was running this command that was stuck, as you probably did to get your stack trace. I took the command line and ran it in a separate Administror cmd.exe (paths might differ per system, the idea is the same).
cd "C:\Program Files (x86)\Google\Cloud SDK"
SET "CLOUDSDK_CORE_DISABLE_PROMPTS=1"
SET "CLOUDSDK_CONFIG=%APPDATA%\gcloud"
"C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\install.bat" --quiet --disable-installation-options --path-update "FALSE" --usage-reporting "true" --additional-components beta powershell"
Running them would produce the same error / stack trace.
Editing log.py and commenting out (prefix with #) line 232 would make it get further, but it runs into a separate problem:
ERROR: Cannot use bundled Python installation to update Cloud SDK in non-interactive mode.
Please run again in interactive mode.
Enable prompts with CLOUDSDK_CORE_DISABLE_PROMPTS envvar and remove --quiet and --disable-installation-options from the install.bat command line and run it again.
SET "CLOUDSDK_CORE_DISABLE_PROMPTS=0"
"C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\install.bat" --path-update "FALSE" --usage-reporting "true" --additional-components beta powershell"
This time it should continue, start a new console where it actually installs the components and eventually finish succesfully.

Alembic error on Heroku: Can't find Python file migrations/env.py

Trying to deploy a Flask app on Heroku, used to work perfectly with other apps, but now when I try to upgrade the db with:
>:heroku run python manage.py db upgrade
I get the following error:

ImportError: Can't find Python file migrations/env.py
The file migrations/env.py is there on my local machine, and in the git repository:

On branch master
nothing to commit, working tree clean
Locally I work on python 3.6.3, tried also to move to python 3.6.4 on Heroku because it says 3.6.3 is not supported, but with no luck.
Locally, it works without problem, I can migrate and upgrade the DB (postgres both locally and on heroku).
Thanks

This happened to me !
Here is how I solved the problem:
I logged into my dyno using
heroku ps:exec
Then I went to my migrations folder, and the env.py was not there.
So I checked my .gitignore, and there was obviously a env* line in it.
So just delete this line, and commit your migrations/env.py on Heroku.

Try to init it first.I also encountered this problem when I implemented the examples in the book.Then I noticed that I had missed initalization.

Upload to Swift Pseudo folders using duplicity

I'm trying to use duplicity to backup files to a Swift Object Storage service offered by RunAbove. The name of the container is "backup" and it has a pseudo folder named "web" inside which I want to place backups.
Duplicity version: 0.6.24
Python version: 2.7.3
python-keystoneclient 1.0.0
python-swiftclient 2.3.1
After setting the necessary environment variables I have tried the following commands:
duplicity --no-encryption /var/www swift://backup/web/
Returns the following error:
Listing of 'backup/web/' failed (attempt 1): JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Then I tried:
duplicity --no-encryption --file-prefix web/ /var/www swift://backup
Which returns python errors:
Local and Remote metadata are synchronized, no sync needed.
Last full backup date: none
No signatures found, switching to full backup.

How do I backup files to a pseudo folder in OpenStack Swift using duplicity?

This issue is fixed in duplicity v0.7.08 (see http://duplicity.nongnu.org/CHANGELOG)
Merged in lp:~ghoz/duplicity/swift-prefix
adds the abiliy to use path in the swift backend, in order to have multiple
backups to the same container neatly organized.

NameError: global name 'output' is not defined
Press enter to continue...
I ve found this solution: https://devnet.madewithmarmalade.com/questions/2784/mkb-fails-to-build.html
but I don't think it's the best solution.
it's working for building the project but I got other problems when I have to deploy with the Marmalade deploy tool.
Sometimes deploy fails and the error in the error log is the same "global name 'output' is not defined"
I m not able to save my configuration in the .mkb, because if I do this, next time I reload the configuration, the deploy fails.

it was my fault, I had marmalade 6.1.1 installed instead of 6.1.2.
6.1.1 doensn't provide retina support and in the .mkb there was the tag "Enable 4-inch Retina Support" set.
