我的烧瓶服务器的行为非常奇怪，我有一条这样的路线
@app.route('/login' , methods=['GET' , 'POST'])
def register():
return render_template('login.html')
这很好，当我要求的时候就给了我页面但随后我将文件名重命名为"；register.html"；
@app.route('/register' , methods=['GET' , 'POST'])
def register():
return render_template('register.html')
现在这给了我一个错误：werkzeug.routing.BuildError:无法为端点"/register"构建url。你的意思是"注册"吗？
现在我多次尝试用不同的名称更改路线路径：
@app.route('/anypathname' , methods=['GET' , 'POST'])
def register():
return render_template('register.html')
它仍然给我错误：werkzeug.routing.BuildError:无法为端点"/register"生成url。你的意思是"注册"吗？
这个错误不应该说"；werkzeug.routing.BuildError:无法为终结点"/anypathname"生成url。你的意思是"任何路径名"吗">
我试图重新启动服务器清除浏览器缓存，flask在代码更改时自动重新加载，它的调试器也在工作。但它仍然给我这个错误
这是我的用户注册的简单示例。由于长度的原因，代码稍微减少了一点。也许这会对你有所帮助。

我指的是"寄存器"；在"；a"；标签链接在"；register.html"；但它应该是"；寄存器"；而不是"/寄存器"；
<a href="{{ url_for('register') }}"><button class="login-btn">Register</button></a>
not:
<a href="{{ url_for('/register') }}"><button class="login-btn">Register</button></a>
