It appears you are missing some prerequisite to build the package from source.
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.
For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).

当我在上面评论时，错误消失了，但是绝对数据库无法正常工作。 但是如果我尝试使用python3 manage.py runserver 然后告诉我错误
from lawyers.views import *
File "/code/data/abc/proj/lawyers/views.py", line 37, in <module>
from django_rq import job
File "/code/data/.local/lib/python3.8/site-packages/django_rq/__init__.py", line 3, in <module>

File "/code/data/.local/lib/python3.8/site-packages/django_rq/decorators.py", line 6, in <module>
from .queues import get_queue
SyntaxError: invalid syntax (queues.py, line 132)
我认为在 django_rq 中显示错误 当键入python3 manage.py runserver时 告诉我可能的解决方案，谢谢，我尝试了很多但未成功
答案 0 :(得分：1)
我为我解决问题 基本上也与python问题 我使用此命令安装python版本 3.7
sudo apt-get install python3.7
然后激活环境
source env/bin/activate
然后我使用此命令安装 requirements.txt 文件
python3.7 -m pip install requirements.txt
我这个错误已解决，不会再显示给我 用于psycopg2的构建轮……错误pip3安装了psycopg2？
然后告诉我
ModuleNotFoundError：没有名为“ pandas”的模块 然后我用这种方式安装
python3.7 -m pip install pandas
当我运行python3.7 manage.py runserver时
然后告诉我错误是django-rq
/code/data/.local/lib/python3.7/site-packages/django_rq/queues.py", line 132
def get_queue(name='default', default_timeout=None, async=None,
^
现在我在python中保留了这个异步字，然后在我的包中将async的名称全部替换为is_async
当我再次运行项目时，请向我显示此错误
django-rq/queues.py然后我通过这种方式解决
import xlsxwriter
ModuleNotFoundError: No module named 'xlsxwriter'
然后再显示一个错误
python3.7 -m pip install xlsxwriter
然后我用这种方式固定
from bs4 import BeautifulSoup
ModuleNotFoundError: No module named 'bs4'
然后我的项目工作正常。 希望我的解决方案对任何人都有帮助。 我暂时需要python3.7版本，所以我不想将其路径更改为python3。
