将Flask应用程序部署到Heroku：ModuleNotFoundError：没有名为＆＃39; lxml＆＃39;

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。

现在解决了。

1. 从requirement.txt中删除tushare，然后执行git commit -am＆＃34;使其更好＆＃34;和git push heroku master，它会被成功推送;

2. 将tushare放回到requirement.txt中，重做git commit -am＆＃34;让它变得更好＆＃34;和git push heroku master。
