将Flask应用程序部署到Heroku: ModuleNotFoundError:没有名为“lxml”的模块

Question

这个烧瓶在我的本地机器上运转良好。然而，当我试图将它部署到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

现在已经解决了。

1. 从requirement.txt中删除tushare，然后执行git提交-am“使其更好”和git推送heroku主，它将被成功地推送；
2. 将tushare放回requirement.txt中，重做git提交-am“让它变得更好”，然后git推heroku主。
