如何为Python 3安装pandas？

Question

我尝试通过执行以下命令为Python 3安装pandas:

sudo pip3 install pandas

结果我得到了这个:

Downloading/unpacking pandas
  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement pandas
Cleaning up...
No distributions at all found for pandas

也许有趣的是,Python 2的安装工作正常.

sudo pip install pandas

返回以下内容:

Requirement already satisfied (use --upgrade to upgrade): pandas in /usr/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): python-dateutil in /usr/lib/python2.7/dist-packages (from pandas)
Requirement already satisfied (use --upgrade to upgrade): pytz>=2011k in /usr/lib/python2.7/dist-packages (from pandas)
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6.1 in /usr/lib/python2.7/dist-packages (from pandas)
Cleaning up...
