Я работаю над уроком «Журнал обучения» в главе 20 из «Ускоренного курса Python» Эрика Маттеса. Я пытаюсь отправить приложение в heroku, но у меня проблема с sdl-config. Он установлен, и я могу просмотреть его в своем каталоге / usr / bin:

 $ ls -lh /bin/sdl-config 
-rwxr-xr-x 1 root root 1.4K Sep 17  2019 /bin/sdl-config
$ ls -lh /usr/bin/sdl-config 
-rwxr-xr-x 1 root root 1.4K Sep 17  2019 /usr/bin/sdl-config
 

Похоже, Heroku не может его найти. Я установил pygame и кучу других библиотек, но безуспешно. Я гуглил в течение 2 часов, и я не ближе, чем когда я начал. кто-нибудь может помочь?

 $ git push heroku master

Обычно ли Heroku требует такого количества вещей, даже для небольших приложений?

Похоже, вы создали свой requirements.txt файл вне активной виртуальной среды. Если вы это сделаете, вы включите все пакеты Python, которые вы когда-либо устанавливали в свою систему. Я думаю, именно поэтому мы видим, что Heroku пытается установить pygame, matplotlib, numpy, pillow и другие. Взгляните на ваш requirements.txt файл, он должен включать только те пакеты, которые вы используете в проекте Django, который вы пытаетесь отправить в Heroku.

Если у вас есть ненужные пакеты, перечисленные в requirements.txt , вы можете воссоздать файл заново. Убедитесь, что вы находитесь в активной виртуальной среде, затем запустите pip freeze > requirements.txt снова. При этом файл будет перезаписан только теми пакетами, которые установлены в виртуальной среде. Открыть requirements.txt и убедитесь, что в нем перечислены только эти пакеты.

Если это выглядит лучше, зафиксируйте свои изменения с помощью Git и попробуйте снова запустить свой проект.
