我无法安装(1.0.28)pip的当前版本。pydot虽然yolk和PyPi都将此版本报告为可用的当前版本，

pip -U pydot

给我

Requirement already up-to-date: pydot in /Library/Python/2.7/site-packages
Requirement already up-to-date: pyparsing in /Library/Python/2.7/site-packages (from pydot)
Requirement already up-to-date: setuptools in /Library/Python/2.7/site-packages (from pydot)

强制使用当前版本

pip -U pydot==1.0.28

给我

Downloading/unpacking pydot==1.0.28
  Could not find a version that satisfies the requirement pydot==1.0.28 (from versions: 1.0.2)
  Some externally hosted files were ignored (use --allow-external to allow).
Cleaning up...
No distributions matching the version for pydot==1.0.28

乃至

pip -U --allow-external pydot pydot==1.0.28

给我
