运行PyTest的属性错误

我目前正试图在某个程序上运行一些测试，但突然间，我不断收到相同的错误，不管我运行的是什么，无论是我想测试的程序，基本教程文件，一个空文件或什么都不是。错误是：运行PyTest的属性错误

我找不到具体涉及在pytest这个bug任何东西，但它似乎使用的六个模块的其他程序发生。我试图重新安装六个和pytest，但到目前为止没有运气。什么是问题以及如何解决它？

相同的想法，打印'六'模块版本，并按照重新安装说明 - http://stackoverflow.com/questions/29164045/error-with-crunchbase-api-wrapper-pycrunchbase –

你确定你正在导入*正确*'六'？ 'print（6 .__ file__，dir（6））'（即它在哪里和它里面）显示什么？ – jonrsharpe

已被添加到问题 – Slereah

缺乏python_2_unicode_compatible和_iteritems，_itervalues存在，......表明您使用的是旧版本的Python六。

准确地说，python_2_unicode_compatible被引入September 2014。

您可以安装pip和virtualenv的更新版本。

更新六（与sudo pip安装 - 升级六）似乎没有工作。此外py.test工作正常，直到几天前，所以我不太确定去年推出的模块。 – Slereah

@Slereah：你使用的是什么版本？尝试'打印（六.__版本__）' –

当前版本是1.5.2 – Slereah
