DistributionNotFound错误：是否存在名为“requirements==0.1”的分发？

Question

我目前正在研究c。elegans模拟器包c302，它需要名为pyopenworm的分发要求。问题是这些需求包括“需求==0.1”

对于所有其他需求，pip安装包_name==版本解决了问题，但pip找不到名为“requirements”的发行版。同样奇怪的是，发行版名称仅仅是“需求”。pip install pyopenworm安装所需的每个发行版，但这也失败了。有没有办法安装这个“requirements==0.1”或者绕过这个错误？这与“requirements.txt”方法不同吗

pip install pyopenworm
Collecting requirements==0.1 (from pyopenworm)
  Could not find a version that satisfies the requirement requirements==0.1 (from pyopenworm) (from versions: )
No matching distribution found for requirements==0.1 (from pyopenworm)

c302 Pha_7 parameters_C -cells ["M1","M2L","M2R","M5","I4","I5","I6"] -cellstostimulate ["M1","M5","I4","I5","I6"]
