python - 我无法在 heroku 上部署我的 flask 应用程序

Question

我是 heroku 的新手，我正试图在那里部署我的应用程序。但它失败了，我收到以下消息:

   Command /app/.heroku/python/bin/python -c "import setuptools, tokenize;__
   file__='/tmp/pip_build_u21590/matplotlib/setup.py';exec(compile(getattr(tokenize
, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" inst
all --record /tmp/pip-4IJQX6-record/install-record.txt --single-version-external
ly-managed --compile failed with error code 1 in /tmp/pip_build_u21590/matplotli
b
Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 70: ordinal

!     Push rejected, failed to compile Python app

To git@heroku.com:salty-oasis-2440.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:salty-oasis-2440.git'

上面是我的要求列表:

• flask ==0.10.1
• configobj==5.0.0
• unicorn ==19.1.1
• itsdangerous==0.24
• jinja2==2.7.2
• matplotlib==1.3.1
• networkx==1.8.1
• numpy==1.8.1
• pyparsing==1.5.7
• python-dateutil==2.2
• werkzeug==0.9.4

我做错了什么？

提前致谢!!!

这不是 Heroku 的问题。这是 known issue with pip有一个未发布的(截至 2014 年 11 月 26 日)修复。由于您使用的是 Python 2.7，您可以 manually patch pip现在。
