Deployment failing
I am trying to deploy some updates to my app and I am getting errors during the build process.

Here is the build log
mysql issue, I seriously recommend switching to postgres, it would be both cheaper and easier
What do I need to do to resolve the issue?
If I was starting from scratch I would go to Supabase or something but for now I have all my code so don't really want to refactor
then I'm sorry but no one has found a good solution to this besides switch to postgres
the best I can say is try different mysql packages
So Railway.app is not compatible with the specific pip application I am installing and I need to go with a different one if I want to use Railway?
this isn't a railway issue
Just to give you a heads up and if you want to see this first hand we can do a screenshare but I am able to build off the exact same Github repo on Heroku and the build completes.
heroku does a lot of hand holding with its builds, railway builds and runs your code as is
Is your position that you are able to support me in doing whatever Heroku is doing to make the build work but refuse to do so or that you don't know how to?
as I've said previously, I have never seen a solution to getting a build with the
mysqlclient package working, it has always been use a different mysql package or switch to postgresIf you want to see it I can do a screenshare to show you Heroku's build working.
Also I am ok with using a differnt MySQL client. Which one do you reccomend for use on Railway?
I'm working in a Python env
as I've said previously, heroku does a lot of hand holding with its builds, railway builds and runs your code as is
as for the mysql package, I'm not sure, as I've said previously, try different mysql packages
Lets say I went to this page: https://docs.railway.app/databases/mysql
And I followed the Railway recommendations for a MySQL server and I have a Python envirionment which library would I use?
as I've said previously, I am not sure
Ok you don't know how to solve the technical problem if the solution is MySQL. I can accept that answer.
Can you please escalate my case to someone on the team that can help?
it should not take too long to try some of the drop in replacements for the package you are using
You're on the hobby plan so unfortunately community help is all you have access to
someone else from the community may know how to solve this
Wait are you a Railway staff employee or a community member?
community member, because as I've said previously, you are on the hobby plan and only have access to community support
I didn't realize that, I thought you were speaking on behalf of the company and refusing to help.
Thank you for the suggestions and sorry for pressing you. I thought it was a staff employee who was not wanting to do the extra digging.
I'll see what I can do with another library or maybe upgrade the plan if needed.
I have legitimately tried to solve this in the past, I could not
that is why I come with the recommendation of switching to postgres
mysql has a base cost of ~ 5$ a month at idle too
I'm going with a cloud provider for MySQL (PlanetScale) which gives 10M row writes and 1B row reas per month up to 5GB storage in the free plan which will keep me going for a while. It works well from my dev envirionment, just need to figure out a way to get it to deploy to railway.
Is there anything in your logs that might give a specific error on what dependency of the package might be conflicting?
I've tried building with a bunch of mysql system packages and all that stuff, nothing seems to work, I truly have no options for you besides try a different client library
Just out of curiosity and hopefully to avoid going down a path that wont work. Do you know if people have had any luck (or failed) with PyMySQL as an alternative?
I think mysqlclient is a c based library vs. PyMySQL which won't be as performant but is written in pure python I htink
I'm not sure, sorry. although it should be very easy to test, throw connect in a main.py file and that package in your requirements.txt file
Agreed. And it seems that the API is the same so a slight modification to the import file and I should be able to test. I'll give it a go locally and then try a deploy and see where I land.
Thank you for your help. One last thing. There was another issue released a few mins before mine about a deployment failing in the requirement.txt. Is that just coincidence or is there a chance that something is up with the deployment system and I should try later?
can you link it?
that was an issue with pip upgrade
ok. I'll plug away and see what i can find
So I think I have MySQL connection code deployed and working.
The client library I am using is pymysql==1.1.0
And I am inserting into PlanetScale.
I hit some glitches at first but now seems to be running smooth. Will have to hit it harder a bit later to be sure. But I think pymysql is a decent drop in replacement for the standard mysql client library for Python deployments.
Thank you for isolating the issue to the mysql library
sounds good!
