python - Flask-Assets 在本地工作但不能在 Heroku 上工作

Question

我正在修改 cookiecutter flask 应用程序。我在 WIN7 本地工作并尝试部署到 heroku。我目前正在尝试向页面添加日期选择器。我找到了https://eonasdan.github.io/bootstrap-datetimepicker/ 。 myflaskapp的结构:

我已经设置了 Bower，通过使用文档根目录中的 .bowerrc 文件在静态根目录下安装前端依赖项，其中包含:

{ "directory" : "myflaskapp/static/bower_components" }

这个cookiecutter使用flask-assets来管理项目 Assets 。正在关注https://adambard.com/blog/fresh-flask-setup/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 Assets :

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，在测试过程中，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。我该如何解决这个问题？

注意:我一直在查看https://github.com/mitsuhiko/flask/issues/348 ，这可能与此有关。

尝试检查您的 .gitignore，构建通常会被忽略，这会在此处排除您的静态文件:bower_components/eonasdan-bootstrap-datetimepicker/build/*
