我正在修改一个cookiecutter Flask 应用程序。我正在本地使用 WIN7 并尝试部署到 heroku。我目前正在尝试将日期选择器添加到页面。我找到了https://eonasdan.github.io/bootstrap-datetimepicker/。myflaskapp的结构：
我已经设置了 bower，通过在包含以下内容的文档根目录中使用 .bowerrc 文件，在静态根目录下安装前端依赖项：
{ "directory" : "myflaskapp/static/bower_components" }
这个 cookiecutter 使用烧瓶资产来管理项目资产。在https://adambard.com/blog/fresh-flask-setup/之后 ，我修改了 myflaskapp/assets.py 文件：
from flask_assets import Bundle, Environment
import os
css = Bundle(
"libs/bootstrap/dist/css/spacelab/bootstrap.css",
"bower_components/eonasdan-bootstrap-datetimepicker/build/css/bootstrap-datetimepicker.css",
"css/style.css",
"css/home.css",
# "css/style.css",
filters="cssmin",
output="public/css/common.css"
)
js = Bundle(
"libs/jQuery/dist/jquery.js",
"libs/bootstrap/dist/js/bootstrap.js",
"bower_components/moment/moment.js",
"bower_components/eonasdan-bootstrap-datetimepicker/build/js/bootstrap-datetimepicker.min.js",
"js/plugins.js",
filters='jsmin',
output="public/js/common.js"
)
assets = Environment()
assets.register("js_all", js)
assets.register("css_all", css)
myflaskapp/app.py 初始化资产：
from flask import Flask, render_template
from myflaskapp.assets import assets
"""
:param config_object: The configuration object to use.
"""
app = Flask(__name__)
app.config.from_object(config_object)
register_extensions(app)
register_blueprints(app)
register_errorhandlers(app)
return app
def register_extensions(app):
assets.init_app(app)
def register_blueprints(app):
app.register_blueprint(public.blueprint)
app.register_blueprint(user.blueprint)
在 myflaskapp/settings.py 中，在测试期间，我设置了：
ASSETS_DEBUG = True # Don't bundle/minify static assets
在本地，控制台中没有错误。在 heroku 上，我收到内部服务器错误。日志：

正如您在顶部屏幕截图中看到的那样，它就在那里。我怎样才能解决这个问题？
注意：我一直在查看https://github.com/mitsuhiko/flask/issues/348，这可能与此有关。
