也许 smb 有同样的错误？ 将非常感谢回答Thx
解决方法
堆栈跟踪似乎表明您没有在目标机器上安装 PostgreSQL 库。因此，要解决该问题，您可以下载软件 here 的稳定版本，并确保在安装过程中检查了开发库。这将要求您在安装后关闭并重新打开所有活动的 cmd 会话。
之后，在 Rails 项目上重新运行 File "app.py",line 6,in <module>
import tendie_dashboard
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\tendie_dashboard.py",line 3,in <module>
import tendie_budgets
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\tendie_budgets.py",in <module>
import tendie_categories
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\tendie_categories.py",line 10,in <module>
engine = create_engine(os.getenv("DATABASE_URL"))
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\env\lib\site-packages\sqlalchemy\engine\__init__.py",line 479,in create_engine
return strategy.create(*args,**kwargs)
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\env\lib\site-packages\sqlalchemy\engine\strategies.py",line 56,in create
plugins = u._instantiate_plugins(kwargs)
AttributeError: 'NoneType' object has no attribute '_instantiate_plugins'
（如果您使用的 bundler 早于 2.1）或 bundle install --force（如果您使用的是 Bundler 2.1 或更高版本），并且应该能够正确编译和运行。
如果它已安装并且不能使用上述选项，请通过执行 bundle install --redownload 重新安装 gem 或使用预发布版本（在开发机器上）通过 gem install pg -f 来查看无论他们能否解决您的问题。
