HI,

I am new to the Otree community and I want to figure out how to put apps in public projects into my projects. I search for the forum and find a similar post(https://www.otreehub.com/forum/1077/), however, I try the method and just can not figure it out.

I download the public projects from the otree hub, then unzip it, put the app(e.g. ultimatum game) file into my unzipped project files and config my settings.py. When I rename my project file from myproject.zip to myproject.otreezip, using the cmd otree zipserver launch, it will raise the error:

Traceback (most recent call last):
  File "C:\Users\ZhuanZ\AppData\Roaming\Python\Python312\site-packages\otree\cli\zipserver.py", line 78, in autoreload_for_new_zipfiles
    project.unzip_to_tempdir()
    ``````
    AttributeError: 'Project' object has no attribute '_proc'
    
while the error also has a post in the forum, but that post don't have comments to solve it.
 
Thanks for your help！

You are supposed to zip/unzip the project with:

otree zip
otree unzip

Don't create a .zip yourself. I don't know if that is the reason for your current issue but you should start with that.

Thanks for your assistance, but there are still some issues.

Otree zip filename is successful, but the otree zip filename has issues as followings.The 'fileone' is my project name.

(otreetest) C:\Users\ZhuanZ\Desktop\Codes>otree unzip fileone.otreezip
Unzipped file. Enter this:cd fileone


(otreetest) C:\Users\ZhuanZ\Desktop\Codes\fileone>otree zip fileone
usage: otree [-h]
otree: error: unrecognized arguments: fileone

if I cd to C:\Users\ZhuanZ\Desktop\Codes>otree zip fileone, it remains the same.
(otreetest) C:\Users\ZhuanZ\Desktop\Codes>otree zip fileone
usage: otree [-h]
otree: error: unrecognized arguments: fileone

Could you please tell me how to solve the problem. Thanks!

you don't need to add fileone at the end, just typing otree zip (in the folder where settings.py is) works

Thanks a lot! That works! Thanks again!
