我在 EC2 上有 Ubuntu 10.10 服务器。我安装了 Python 3.1，现在我想在其上安装 NumPy。我该怎么做？我试过了，easy_install-3.1 numpy但出现了这个错误：

答案1
代码来自这个分支numpy 似乎包含一个修复程序。
以下是代码片段和相关注释：
643 # XXX Hack to get numpy installable with easy_install.
644 # The problem is easy_install runs it's own setup(), which
645 # sets up distutils.core._setup_distribution. However,
646 # when our setup() runs, that gets overwritten and lost.
647 # We can't use isinstance, as the DistributionWithoutHelpCommands
648 # class is local to a function in setuptools.command.easy_install
649 if dist is not None and \
650 repr(dist).find('DistributionWithoutHelpCommands') != -1:
651 return None
652 return dist
但是，如果您不想这样做，请尝试python3.1 setup.py install在提取 numpy 的目录中进行操作。这样可以避免代码注释中描述的 easy_install 问题。
答案2
尝试这个命令来安装 numpy
sudo apt-get install python-numpy
答案3
因为 NumPy 不适用于 Python 3.x，与许多其他库一样
