python - AttributeError：“ParsedRequirement”对象在 PIP 21.1.1 中没有属性“req”

Question

我目前正在将项目从 Django 2.1 升级到 Django 2.2。这样做时，我在执行pip install -r requirements.txt.

Running command git clone -q git://github.com/user/djangocms-comments /tmp/pip-req-build-x00esn
u5 
        ERROR: Command errored out with exit status 1:

            install_requires = [str(ir.req) for ir in requirements]
        AttributeError: 'ParsedRequirement' object has no attribute 'req'
        ----------------------------------------

看来该软件包djangocms_comments在使用 pip 的方式上已经过时了。我通过搜索这个网站收集了这么多。但是，我不确定如何解决这个问题。

错误发生在这里。任何帮助或指导将不胜感激。
