报错原因:

注意这种报错要仔细看ERROR里面提供了什么信息

这次错误的原因是django-oscar-paypal里面的

make sandbox

里面的pip -r install requirements.txt里面的setuptools_scm找不到合适的版本导致的.

那么解决方案是:

在pip  install -r requirements.txt之前,

先运行pip install  setuptools_scm,

然后再运行pip install -r requirements.

也就是说我们不使用requirements.txt中指定的setuptools_scm的版本,而是使用自定的setuptools_scm的版本,

这样问题就可以解决了.
