我对Python Web编程还很陌生。请在运行测试应用程序时请求您的协助以解决我遇到的错误。尝试从Powershell运行命令-pythonrun.py。它给出了标题中给出的错误。 Trying the instructions provided in this link

您尚未从flask导入render_template。您需要先导入它。
from flask import render_template
答案 1 :(得分：-1)
我猜因为您使用的render_template不正确。
应该是flask.render_template()
以更好的方式使用它（或更好），您只需将其从烧瓶中导入为
from flask import render_template
