我正在用flask（对于python）编写一个项目，而当我从pycharm运行该项目（包括html文件）时，它给了我以下错误： enter image description here
错误与home.html中的第192行有关。
然后...这是html文件，这会引起问题：-（

我不明白问题是什么，所以我希望这里的一位天才能够揭露我的错误。
答案 0 :(得分：5)
代码结尾附近
<script src="{{ url_for('static', filename='vendor/bootstrap/js/bootstrap.bundle.min.js"></script>
应该是
<script src="{{ url_for('static', filename='vendor/bootstrap/js/bootstrap.bundle.min.js')}}"></script>
您错过了'，)和}}

浏览调用堆栈，查看堆栈何时从调用更改为 jinja2 而不是对您的 HTML 页面之一的更改，例如：
File "C:\Program Files (x86)\Python37-32\lib\site-packages\jinja2\_compat.py", line 37, in reraise
raise value.with_traceback(tb)
File "c:\DEV\a-flask\base\templates\base.html", line 55, in template
<script src="{{url_for('static', filename='js/jquery-ui.min.js"></script>
File "C:\Program Files (x86)\Python37-32\lib\site-packages\jinja2\environment.py", line 1005, in render
return concat(self.root_render_func(self.new_context(vars)))
我去了base.html的第55行：
<script src="{{ url_for('static', filename='js/jquery-ui.min.js }}"></script>
解决方法是包括最后一个引号和缺少的括号：
<script src="{{ url_for('static', filename='js/jquery-ui.min.js') }}"></script>

唯一的问题在于'url_for'函数的语法。
检查''标记和文件名。
<script src="{{ url_for('static', filename='vendor/bootstrap/js/bootstrap.bundle.min.js"></script>
将上面的代码更改为此-
<script src="{{ url_for('static', filename='vendor/bootstrap/js/bootstrap.bundle.min.js')}}"></script>
