Heroku TypeError:parse_requirements()缺少1个必需的关键字参数:'session'

Question

我正试图用Heroku上的雪松将一个应用程序用于雪松-14堆栈.在我的requirements.txt文件中,我有:

....
robobrowser==0.5.1
....

当我尝试通过将项目推送到heroku进行部署时,我得到:

Collecting robobrowser==0.5.1 (from -r requirements.txt (line 17))
     Downloading robobrowser-0.5.1.tar.gz
       Traceback (most recent call last):
         File "<string>", line 20, in <module>
         File "/tmp/pip-build-PqCF2A/robobrowser/setup.py", line 38, in <module>
           for requirement in parse_requirements('requirements.txt')
         File "/app/.heroku/python/lib/python2.7/site-packages/pip-6.0.6-py2.7.egg/pip/req/req_file.py", line 19, in parse_requirements
           "parse_requirements() missing 1 required keyword argument: "
       TypeError: parse_requirements() missing 1 required keyword argument: 'session'
       Complete output from command python setup.py egg_info:
       Traceback (most recent call last):

         File "/tmp/pip-build-PqCF2A/robobrowser/setup.py", line 38, in <module>

           for requirement in parse_requirements('requirements.txt')

         File "/app/.heroku/python/lib/python2.7/site-packages/pip-6.0.6-py2.7.egg/pip/req/req_file.py", line 19, in parse_requirements

           "parse_requirements() missing 1 required keyword argument: "

       TypeError: parse_requirements() missing 1 required keyword argument: 'session'

       ----------------------------------------
       Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-PqCF2A/robobrowser

我怎样才能解决这个问题？

Answer 1

我遇到了为Python安装wabbit_wappa的问题.我通过更改setup.py中的一行来"修复"它:

install_reqs = parse_requirements('requirements.txt')

至

install_reqs = parse_requirements('requirements.txt', session=False)

它安装得很好.

Answer 2

在robobrowsergithub问题跟踪器中有一个未解决的问题和一个拉取请求:

• 已更新pip 6.0+的要求以包含会话

要么等待它被合并,要么robobrowser从fork 安装:

$ pip install git+https://github.com/xxinfinityxx/robobrowser

降级pip也可以是一个选项,但我不确定你是否可以控制在heroku上使用哪个pip版本.
