将 Flask 应用程序部署到 Heroku：ModuleNotFoundError: No module named 'lxml'

Question

烧瓶在我的本地机器上运行良好。但是，当我尝试将其部署到 heroku 时，我陷入了部署步骤： git push heroku master

错误是： ModuleNotFoundError: No module named 'lxml'

谢谢！

看来heroku已经成功下载了lxml模块，我怀疑路径有问题。

Answer 1

现在解决了。

1. 从requirement.txt中删除tushare，然后执行git commit -am "make it better"和git push heroku master，就会推送成功；

2. 将 tushare 放回 requirements.txt，重做 git commit -am "make it better" 和 git push heroku master。
