为什么pip不能安装最新版的deap？

Question

Pypi 说there is a new version on their website。

pip search 告诉我我有一个旧版本，还有一个新版本。

(Canopy 64bit) Johns-iMac:~ john$ pip search deap
deap                      - Distributed Evolutionary Algorithms in Python
 INSTALLED: 1.0.1
 LATEST:    1.0.2

但是 pip install -U 和所有覆盖都表示没有新版本。

(Canopy 64bit) Johns-iMac:~ john$ pip install -U --allow-unverified --allow-external deap==1.0.2
Collecting deap==1.0.2
Could not find a version that satisfies the requirement deap==1.0.2 (from versions: 0.9.1, 0.9.2, 1.0.0rc3, 1.0.0, 1.0.1)
No distributions matching the version for deap==1.0.2

我忽略了哪些愚蠢的细节？

我有同样的行为。如果您不需要稳定版本，您可以从主存储库安装https://github.com/DEAP/deap

pip install git+https://github.com/DEAP/deap

pip search deap
deap                      - Distributed Evolutionary Algorithms in Python
INSTALLED: 1.1.0
LATEST:    1.0.2
