I have a simple code that creates an album in imgur, via pyimgur. This is the code:
#app.route('/get_album')
def get_album():
im = pyimgur.Imgur(CLIENT_ID)
new_album = im.create_album()
return new_album.link
(I tried with im = pyimgur.Imgur(CLIENT_ID) line before the route handlers as well, same thing happens)
On Windows, everything is perfectly fine. However, when I upload the code to my VPS, I get the following error when I try to do something with the api:

I updated flask to the latest version, and I've been using pyimgur 4, latest release I got from github (pip install doesnt work so I had to install it manually, on both Windows and Ubuntu, since some error about setup.py pops out. I used python setup.py install command)
OK, so I have found a solution. The solution was a change in requests module, which probably came along with updated flask or something, so the old method didn't behave like it used to. I updated the requests as well on my VPS (forgot to do it when upgrading flask), and the issue is now solved.

I am building a simple “Hello World” using Python, Flask and the Shopify Embedded SDK. Following this tutorial----> https://medium.com/#dernis/shopify-embedded-sdk-with-python-flask-6af197e88c63.
After doing all the work when I go to the link ' https://localhost:5000/shopify/install?shop=khawaja-kaleem-com.myshopify.com ' to install the application to test store it gives me this error. Need to fix it.

You need to specify the API version you wish to use. Set the version before you make any calls. 2020-10 is the default for now.
See the documentation, it explains everything to you.
https://help.shopify.com/en/api/versioning
The ShopifyAPI package specifies the allowed versions in the 'shopify/api_version.py' file. In my case the Shopify platform latest API version is '2022-10' but the latest version allowed by the ShopifyAPI package is '2022-07'.
It seems that the ShopifyAPI package is not always updated quickly after the release of a new API version on the Shopify platform. Try aligning the API version to one of the versions allowed to work around this error.
When a user goes on my flask app with a URL that has more than 3 sub paths, like "domain.com/var1/var2/var3/var4", it throws the error below:

It works fine for url's that have less than or equal to 3 subpaths like "domain.com/var1/var2/var3", but I have routes for url's with 1, 2, and 3 subpaths.
How can I get my app to go to the 404 Page Not Found method instead of throwing this error?
Thank you!
edit..
Here's a pastebin of the route methods I'm using. http://pastebin.com/kjYsqk9n
Sorry I can't provide an example of this problem, it's really weird and I don't know how to reproduce it myself. My other flask apps work fine, this one doesn't. If anyone needs clarification, please let me know... thanks for all your help!
Found out why it was returning that error. It turns out I was passing in the error object instead of "404" at the end of this line:
return render_template("error.html", usa=usa, canada=canada, breadcrumbs=breadcrumbs, error_code=e), 404
Thanks!
I am using flask-dance to authenticate to Google's servers.

However, I am getting Warning: Scope has changed from "profile email" to "". after you go through Google's credential dialog box.

If I do os.environ['OAUTHLIB_RELAX_TOKEN_SCOPE'] = '1' it works, but I don't think this is a solution but more of a workaround for now. :(
I opened a ticket on the issue Google OAuth2 returns no scope on authentication breaks scope test #306 on the issue.
From what I can tell from https://www.rfc-editor.org/rfc/rfc6749#section-3.3, Google isn't required to return the scope (unless the scope was changed), am I reading this correctly?
Nearest thing I can figure is there is a bug in the oauthlib plugin which I opened a bug report with already.
From the bug report, you can fix the issue by changing the file /oauth2/rfc6749/tokens.py in the plugin on Line 30 from self._new_scope = set(utils.scope_to_list(params.get('scope', ''))) to self._new_scope = set(utils.scope_to_list(params.get('scope', old_scope)))
Fix was merged: https://github.com/idan/oauthlib/pull/323
I'm trying to enable "User-Restricted Resource Access" in my eve application with Basic Authentication. http://python-eve.org/authentication.html#user-restricted-resource-access
The Problem is since I enabled it I get for every http request on the API a "500 error"
If I fire up the API without basic authentication params I get a bad credentials error, so the Basic Authentication works fine.

I'm using eve 0.3 installed with easy_install
You are reading the documentation about the development version (as stated on all pages at python-eve.org.) One relevant change coming with v0.4 is the way auth tokens are set. So basically, you are applying 0.4-dev syntax to Eve v0.3. You should probably follow these instructions instead.
PS: 0.4 is due for release real soon so you might want to stick with that one, so you don't have to update your code again soon.
I am trying to get my Google App Engine app to work with Flask-SQLAlchemy. I am getting the error:
AttributeError: 'module' object has no attribute 'paramstyle'
I have followed the instructions in this answer (Local MySQLdb connection fails with AttributeError for paramstyle when running GAE development server) and so I no longer get the error in the interactive console (when I make an app context).
However, the error still appears when I run the app in my local GAE. Why is this still happening? I am running OSX Mavericks. The full trace:

EDIT: In attempting to further diagnose the issue, when I import MySQLdb in the GAE Interactive Console (in the browser) I get the error ImportError: No module named _mysql
After looking around and debugging for far too long, I finally discovered the issue. When you run the GAE development server, the dev_appserver must be told exactly which MySQL instance you want to connect to. The connection string you use (e.g. in Python) doesn't matter. The connection string only determines database name and instance. However, SQLAlchemy can figure it out fine if you run form an ipython console. This may be due to a different driver being used under the hood.
Hopefully this saves someone else a lot of hair-pulling. Run your dev_appserver.py like so:
dev_appserver.py --mysql_host=<Cloud SQL IP> --mysql_user=root --mysql_password=<Cloud SQL root password> <application directory>
