我想部署他们在入门部分提到的应用程序。但是我收到错误ModuleNotFoundError: No module named 'six'。整个构建日志如下：将django应用程序部署到Heroku时导入错误

我甚至已经安装了six模块，但它不工作。

它看起来好像是在setuptools中触发[此问题]（https://github.com/pypa/setuptools/issues/1042）。 – Alasdair

你可以尝试把'six'放在requirements.txt文件的顶部 –

我试过了，但它没有安装它并直接移动到第二个依赖项。 –

你（非常久远了很多其他人的）都面临着this issue

upgrade your CI environment to just short of v36 with the following pre-install command:

pip install --upgrade "setuptools < 36"

然后，确保即将被创建的virtualenv继承该版本具有以下环境变量：

VIRTUALENV_NO_DOWNLOAD=1

另一解决方法是通过安装模块six之前运行任何其他命令。

Github回购的官方回应是它将尽快修复。希望它有效。干杯!

我安装了六个模块，然后完成了从一开始的所有步骤，但它也给出了错误。 –

是否与以前一样？ – TheDarkKnight

是 - > ModuleNotFoundError：没有名为'six'的模块 –
