ImportError:libpq.so.5:无法打开共享对象文件:没有这样的文件或目录

Question

(我的操作系统是fedora 34(

我将django与haystack和postgresql一起使用。出于开发目的，我运行heroku local命令。我使用三个文件进行设置：base.py，local.py，pro.py。当我运行heroku时，我使用local.py文件：

from . base import *
DEBUG = True
SECRET_KEY='secretKey'
DATABASES = {
'default': {
'ENGINE':'django.db.backends.sqlite3',
'NAME':os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
if DEBUG:
INTERNAL_IPS = ('127.0.0.1', 'localhost',)
DEBUG_TOOLBAR_PANELS = [
'debug_toolbar.panels.versions.VersionsPanel',
'debug_toolbar.panels.timer.TimerPanel',
'debug_toolbar.panels.settings.SettingsPanel',
'debug_toolbar.panels.headers.HeadersPanel',
'debug_toolbar.panels.request.RequestPanel',
'debug_toolbar.panels.sql.SQLPanel',
'debug_toolbar.panels.staticfiles.StaticFilesPanel',
'debug_toolbar.panels.templates.TemplatesPanel',
'debug_toolbar.panels.cache.CachePanel',
'debug_toolbar.panels.signals.SignalsPanel',
'debug_toolbar.panels.logging.LoggingPanel',
'debug_toolbar.panels.redirects.RedirectsPanel',
]
DEBUG_TOOLBAR_CONFIG = {
'INTERCEPT_REDIRECTS': False,
}

export DJANGO_SETTINGS_MODULE=myshop.settings.local

但是heroku显示了这个错误：
