升级Python包dateutil：找不到版本

Question

我尝试使用dateutil将2.5.3从2.6.0升级到最新版pip install dateutil --upgrade，但问题为Could not find a version。

$ pip install dateutil --upgrade
Collecting dateutil
  Could not find a version that satisfies the requirement dateutil (from versions: )
No matching distribution found for dateutil

我检查了帖子Could not find a version that satisfies the requirement 。正在运行pip freeze | grep dateutil，

$ pip freeze | grep dateutil
python-dateutil==2.5.3

我如何知道哪个版本满足我的机器？是否可以将dateutil升级到最新版本？

Answer 1

是

pip install python-dateutil --upgrade
