1, sometimes the system installation heroku, but in order not break below the command.
The reason may be inadequate heroku installation directory, it is best to heroku installed outside the project folder.
2、Heroku: “No default language could be detected for this app” error thrown for node app
The error is the meaning: " no default language for the application can be detected" error thrown node application
solution:
Directory might be a problem. I just started a directory is wblog following two files, .idea / and wblog /, wblog / below is the real project, to establish a Git repository is the first wblog /, later changed to the second wblog / as warehouse, and finally the problem is solved.
3, pushed heroku error heroku config: set DISABLE_COLLECTSTATIC = 1
Reference Hirofumi: https: //blog.csdn.net/wbdxz/article/details/81261648
4, the file is too large, upload failed fatal: the remote end hung up unexpectedly
solution:
Execution: git config --global HTTP .postBuffer 2.428 million can be.
5, git push heroku master error

solution:
I runtime.txt inside the python changed to 3.6.8
Then there will be some mistakes,
