关于在heroku上的部署问题

2016-09-20T08:03:32.269749+00:00 app[web.1]: from itsdangerous import json as _json

2016-09-20T08:03:32.269828+00:00 app[web.1]: from operator import _compare_digest as compare_digest

2016-09-20T08:03:32.269851+00:00 app[web.1]: ImportError: cannot import name _compare_digest

重新虚拟了一个python环境，部署也成功了。但是在本地运行正常，放到上边就出问题了。。。

@Malxi 没有用过，hmac是heroku的环境特有的文件吗？

[Malxi]

@littlecodersh hamc 是 python 中的一个模块。。。好像，这里是在itsdangerous.py中导入了这个模块

[littlecodersh]

@Malxi 现在修复了这个问题了么？

[Malxi]

@littlecodersh 没有，我尝试让它在云上安装hashlib， hmac （这两个是自带的模块。。。） 然后就无法安装了。。。 -----> Python app detected

解决了，犯了个愚蠢的错误。。。

[littlecodersh]

@Malxi OK，分享一下解决方法吗？

[Malxi]

@littlecodersh 。。。我就一渣渣，看看部署的教程就可以了。

[littlecodersh]

也行吧，那我把这个issue关掉了
