Python 在Ubuntu 12.04上升级到numpy 1.8.0

我正在运行Ubuntu12.04，它默认附带

Numpy1.6.0

（我已经安装了

Python2.7.3

）。由于这个问题的答案，我需要升级它

我从下载了

1.8.0版
的
.tar.gz
软件包，将其解压缩，移动到文件夹中并运行以下命令：

python setup.py build --fcompiler=gnu95
python setup.py install --user

如本问题和中所述：

这导致
NumPy
不再在
Spyder
中加载，现在显示错误：

Traceback (most recent call last):

    from sre_constants import *
  File "/usr/local/lib/python2.7/sre_constants.py", line 18, in <module>
    from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT

它还删除了
matplotlib
和
scipy
。因此，我尝试使用以下工具重新安装它们：

sudo apt-get install python-numpy python-scipy python-matplotlib

但这失败了，错误如下：

Traceback (most recent call last):

从sre_常量导入*
文件“/usr/local/lib/python2.7/sre_constants.py”，第18行，在
从_sre导入MAXREPEAT
ImportError:无法导入名称MAXREPEAT

现在我没有运行python，甚至不知道如何回到以前的稳定版本。所以问题是：我能在我的系统中至少安装
1.7.1
版本吗？如果不能，我如何回到正常工作的
1.6.0
版本？谢谢。
好的，所以我试着：

pip uninstall numpy

它返回：

Successfully uninstalled numpy

于是我做了：

pip install numpy

但它说：

Requirement already satisfied (use --upgrade to upgrade): numpy in /home/gabriel/.local/lib/python2.7/site-packages
Cleaning up...

显然它还在那里。我删除了该文件夹的内容，然后简单地执行了以下操作：

sudo pip install numpy

这真是不可思议的魔法。现在我已经安装了
NumPy 1.8.0、SciPy 0.12.0、Matplotlib 1.2.1
，一切都正常运行

sudo pip install numpy --upgrade

将以更少的努力完成同样的事情。
更多的标准答案，应该很快就会在OP的答案之上投票，希望我有Ubuntu 12.04LTS和Python 2.7.3，当我在Python中运行
numpy.version.version
时，发现我有1.6。然后我完成了你的
sudopip安装numpy——升级
，下载了numpy1.9源代码，并进行了构建。但是回到Python2.7.3
numpy.version.version
。。。1.6（再次）。没有变化。因此，我运行了
sudo apt get build dep python numpy
，以直接获得最新的构建依赖项，并重复了
--升级
构建。同样的结果。。。1.6.好吧，我可能在这里搞错了，因为我没有意识到我是从一个规范二进制文件开始的，而不是从一个pip构建开始的。
