How to update your old custom apps(built on v9 and below) to install on latest versions

[kt2152]

Now this seems the most common problem i have seen in many posts regarding either creating or installing new apps –
saw a few solutions which actually does not apply to apps built on v9 , v8 and before ,

Create new app failed with error Command "python setup.py egg_info" failed with error code 1

@kolotayo i solved this 1 by : i open file setup.py inside your new app module i saw this code not correct [step 1] i fixed the code to : [step 2] after that, i copy this ./env/bin/pip install -q -e ./apps/crook --no-cache-dir to my ssh at frappe-bench folder and enter [step 3] after that i put the new module name inside /home/frappe/frappe-bench/sites/apps.txt [step 4] and i install the module to the site i want to install it… install like usual with bench --site [sitename] instal…

the solution in this suggests changing some minor texts in setup file ,
but the thing is the app i built on v8 , the setup file doesn’t look anything like this, not even the file structure ( what is this egg_info files)

file structure and setup files look something like this

which gives below error while installing ,

are there simple steps to make these old apps compatible and install on the latest versions , v10 and v11 ?

Hi try it

./env/bin/pip install --upgrade pip==9.0.3

Thanks , it does solve the problem currently ,

but i wouldn’t say its a proper final solution to need to roll back pip everytime ,
instead there should be something that will upgrade the applications themselves to be compatible to latest versions of everything.

thanks for the help though

for the pip issue we do this

try: # for pip >= 10
    from pip._internal.req import parse_requirements
except ImportError: # for pip <= 9.0.3
   from pip.req import parse_requirements

in setup.py
