python - Freeze 方法在 Frozen Flask 中遇到文件存在错误

问题描述

有谁知道如何使用冷冻瓶？？？我需要帮助制作网站并将其托管在 github 上。我在 github 上托管它没有问题，但是我在实际的 freeze() 过程中遇到了问题。它工作了一点，但后来我遇到了 FileExistsError。但我没有任何同名的文件。views.py 路由设置得如此笼统，以至于它需要 state/state-abbreviation/other。

from flask_frozen import Freezer
from flask import Flask
from website import app

freezer = Freezer(app)
app.config.from_pyfile('settings.py') #use this to not delete files after freezing, and move all static files into project directory for GH to see.

if __name__ == '__main__':
    freezer.freeze()
    # app.run(debug=True)

from flask import render_template, Blueprint, url_for

@core.route('/')
def index():
    return render_template("index.html", states=states_array, other=Other_Resources)


@core.route('/state/<state_code>')
def state(state_code=None):
    if state is None:
        raise ValueError('No state given')
    title = states_dict[state_code]
    return render_template('state_home_page.html', title=title, states=states_array, code=state_code, other=Other_Resources)


@core.route('/state/<state_code>/donate')
def state_donate(state_code=None):
    title = states_dict[state_code]
    try:
        data = state_to_category['Donate'][state_code]
    except KeyError:
        data = []
    return render_template('state_donate.html', title=title, states=states_array, data=data, code=state_code, other=Other_Resources)

@core.route('/state/<state_code>/organizations')
def state_org(state_code=None):
    title = states_dict[state_code]
    try:
        data = state_to_category['Organization'][state_code]
    except KeyError:
        data = []
    return render_template('state_org.html', title=title, states=states_array, data=data, code=state_code, other=Other_Resources)

@core.route('/state/<state_code>/blackbusiness')
def state_biz(state_code=None):
    title = states_dict[state_code]
    try:
        data = state_to_category['Business'][state_code]
    except KeyError:
        data = []
    return render_template('state_biz.html', title=title, states=states_array, data=data, code=state_code, other=Other_Resources)

@core.route('/State_list')
def State_list():
    return render_template("state_list.html", states=states_array, other=Other_Resources)

@error_pages.app_errorhandler(404)
def error_404(error):
    return render_template('error_pages/404.html', states=states_array), 404

而且我认为它在冻结 state/ca/ 之后会搞砸，然后尝试冻结 state/ca/donate 等等。

这是我的回购https://github.com/mrodriguez3313/Support-bipoc请检查一下，以便您可以分叉并自己尝试。我有一个分支，我在其中进行了测试，称为 MAR-freezingapp。你可以看到我所做的尝试。Frozen Flask 文档听起来应该“正常工作”，当您运行 .freeze() 方法时，它会在 build/ 文件夹中为您创建静态文件。但是当我跑步时python app.py

这些是我得到的错误

我尝试查看是否可以将 .freeze() 包装在 try/except 中，但它仍然停止。也许我做得不对？我尝试运行 freeze.run(debug=True)，但它也只是因相同的错误而中断。我仍然可以使用flask run. 提前感谢您的帮助！

解决方案

我克隆了您的项目，并且在core/views.py. 我的项目遇到了类似的问题，在我的路线中添加斜杠解决了这个问题。更多相关讨论：https ://www.reddit.com/r/flask/comments/335cyi/a_problem_with_frozenflask/

Frozen Flask 也不能保证它在任何情况下都“正常工作”。例如，在文档中，他们提到在某些情况下需要编写 url 生成器。（https://pythonhosted.org/Frozen-Flask/#url-generators），尽管这似乎与您的应用程序无关。
