我正在尝试使用beautifulsoup来制作一个行机器人，并将代码推送到Heroku。
我的代码可以在本地运行，但是在推送到Heroku后出现以下错误：

我该如何解决这个问题？
答案 0 :(得分：0)
您的构建输出说
Skipping installation, as Pipfile.lock hasn't changed since last deploy
表示您同时拥有requirements.txt（由pip使用）和Pipfile + Pipfile.lock（由pipenv使用）。在这种情况下，Heroku使用pipenv从您的Pipfile.lock安装锁定的依赖项，而完全忽略了您的requirements.txt。
选择一个工具，确保其文件是最新的，然后删除另一个工具的文件。提交并重新部署。
