django.db.utils.OperationalError: FATAL:  password authentication failed for user "postgres"

Answer 1

您应该在 settings.py 中添加正确的 postgres 用户密码，如 FATAL: password authentication failed for user "postgres"

Answer 2

为postgres设置密码

sudo -u postgres psql

在 psql 终端中

\password postgres

设置密码并将其添加到您的settings.py 文件中
