Я работаю Python 3.7, Django 2, на Ma c OS X. Когда я запускаю следующие команды из командной строки, они работают без проблем ...
localhost:web davea$ source ./venv/bin/activate
(venv) localhost:web davea$ python manage.py migrate maps
System check identified some issues:
WARNINGS:
?: (mysql.W002) MySQL Strict Mode is not set for database connection 'default'
HINT: MySQL's Strict Mode fixes many data integrity problems in MySQL, such as data truncation upon insertion, by escalating warnings into errors. It is strongly recommended you activate it. See: https://docs.djangoproject.com/en/2.0/ref/databases/#mysql-sql-mode
Operations to perform:
Apply all migrations: maps
Running migrations:
No migrations to apply.
Однако, когда я создаю сценарий bash, содержащий команды
!#/bin/bash
source ./venv/bin/activate
python manage.py migrate maps
Этот сценарий умирает
localhost:web davea$ sh test.sh
test.sh: line 1: !#/bin/bash: No such file or directory

Did you install mysqlclient?
Я выяснил с помощью моих друзей в комментариях, что проблема в том, что некоторые env vars недоступны из моего bash скрипта. Вместо того, чтобы указывать c переменную cherry-pick, я хотел бы знать, как передать весь мой набор переменных среды сценарию до его запуска.
