这是我在更新后在heroku中打开应用程序的结果。
应用程序错误 应用程序中发生错误，无法提供您的页面。如果您是应用程序所有者，请检查日志以获取详细信息。您可以使用以下命令从Heroku CLI执行此操作 heroku日志--tail
这是我进行更新时执行的过程：
heroku login
heroku info
heroku git:remote --app tcwhais
git add .
git commit -m "first update"
git heroku push master
heroku open
由于无法打开网络，因此我执行了以下操作： 我安装了Heroku CLI（64位）
heroku login
heroku git:clone -a tcwhais
cd tcwhais
git add .
git commit -am"to correct error"
git push heroku master
heroku open
这是更新日志：
