我使用flask，当我调用这个url时出现这个错误：/login这是我的登录方法：
@app.route('/login')
def login():
if authenticateForPanel():
return redirect(url_for("panel"))
else:
getParam = request.args.getlist('redirect_uri')
if getParam:
ref =getParam[0]
else:
ref="/panel"
return render_template( themesDir + g.blogOptions['active_theme']+'/login.html', blogOptions = g.blogOptions, ref=ref )
And the traceback:
和回溯：

TemplateNotFound: static/themes/default/login.html
I am absolutely sure the login.html is there(static/themes/default/404.html).Why can this occur?
我绝对确定 login.html 在那里（static/themes/default/404.html）。为什么会发生这种情况？

I think you shouldn't prepend themesDir. You only pass the filename of the template to flask, it will then look in a folder called templatesrelative to your python file.
我认为你不应该预先准备themesDir。您只需将模板的文件名传递给flask，然后它就会在一个名为templates相对于您的python 文件的文件夹中查找。

You put your template in the wrong place. From the Flask docs:
您将模板放在错误的位置。来自 Flask 文档：
Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it's a package it's actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates
Flask 将在模板文件夹中寻找模板。因此，如果您的应用程序是一个模块，则此文件夹位于该模块旁边，如果它是一个包，则它实际上位于您的包中：有关更多信息，请参阅文档：http: //flask.pocoo.org/docs/quickstart/#rendering-模板
