【问题描述】：
我正在按照https://www.udemy.com/course/the-ultimate-beginners-guide-to-django-django-2-python-web-dev-website/learn/lecture/9517168#overview 指南在带有 Postgres 数据库的 Digital Ocean 服务器上构建 Django 网站。
老师所遵循的指南是官方的Digital Ocean设置指南https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04#creating-and-configuring-a-new-django-project
一切都很好，直到我尝试在服务器端迁移项目：
-
我在终端中运行的第一种语法
python manage.py makemigrations -
第一个错误
File "manage.py", line 16 ) from exc ^ SyntaxError: invalid syntax -
我在终端中运行的第二个语法
python3 manage.py makemigrations -
第二个错误
Traceback (most recent call last): File "manage.py", line 21, in <module> main() File "manage.py", line 17, in main execute_from_command_line(sys.argv) File "/home/djangodeploy/.local/lib/python3.6/site-packages/django/core/management/__init__.py", line 371, in execute_from_command_line utility.execute() File "/home/djangodeploy/.local/lib/python3.6/site-packages/django/core/management/__init__.py", line 317, in execute settings.INSTALLED_APPS File "/home/djangodeploy/.local/lib/python3.6/site-packages/django/conf/__init__.py", line 56, in __getattr__ self._setup(name) File "/home/djangodeploy/.local/lib/python3.6/site-packages/django/conf/__init__.py", line 43, in _setup self._wrapped = Settings(settings_module) File "/home/djangodeploy/.local/lib/python3.6/site-packages/django/conf/__init__.py", line 106, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/lib/python3.6/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 994, in _gcd_import File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 955, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 665, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 678, in exec_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "/home/djangodeploy/portfolio-project/portfolio/settings.py", line 137, in <module> from .local_settings import * File "/home/djangodeploy/portfolio-project/portfolio/local_settings.py", line 5 DATABASES = { ^ IndentationError: unexpected indent 我已经修改了原来的settings.py文件，将下面的内容放到了底部，如django local_settings import error
try:
from .local_settings import *
except ImportError:
pass
- 我还尝试了导入设置更正（更改了用于发布的数据库数据的值）Django Local Settings
from settings import *
SECRET_KEY = 'MY_SECRET_KEY'
DEBUG = False
ALLOWED_HOSTS = ['164.143.264.187']
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'my_name',
'USER': 'the_user_nameing_i_have',
'PASSWORD': 'my_key',
'HOST':'localhost',
'POSRT': '6432',
}
}
我仍然得到原来的错误。
我的 manage.py 文件我已经尝试了这两个选项
"""

if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "portfolio.settings")

更新 1 基于 Pranita Gandhi 的评论
我已卸载服务器 VENV 中的所有 4 个库
在本地机器上，我创建了原始 venv 的 requirements.txt 为 Pranita Gandhi 推荐了它。然后把它放到服务器上并尝试将它安装到现在空的服务器 venv。
pip3 install -r requirements.txt
- 我收到以下错误：

更新 2
我试图强制安装基于 https://github.com/googlesamples/assistant-sdk-python/issues/236 / moham96 于 2018 年 4 月 20 日发表评论
您正在尝试将软件包安装到您没有写入权限的系统文件夹中。 您有三个选项（仅使用其中一个）：
- 1-设置一个虚拟环境来安装包（推荐）：
python3 -m venv env
source ./env/bin/activate
python -m pip install requirements.txt
- 2-将包安装到用户文件夹：
python -m pip install --user requirements.txt
- 3-使用sudo安装到系统文件夹（不推荐）
sudo python -m pip install requirements.txt
不幸的是，这些都没有解决我的问题。

你能发布你的 manage.py 文件吗？
