Upgrade to numpy 1.8.0 on Ubuntu 12.04
提问by Gabriel
I'm running Ubuntu 12.04 which comes by default with NumPy 1.6.0(I have, actually had, Python 2.7.3installed). As a result of the answer to this question polyfit() got an unexpected keyword argument 'w', I need to upgrade it.
我运行Ubuntu 12.04自带其默认使用NumPy 1.6.0（我有，其实有，Python 2.7.3安装）。由于对这个问题的回答polyfit() 得到了一个意外的关键字参数 'w'，我需要升级它。
I downloaded the .tar.gzpackage for the version 1.8.0from here, unpacked it, moved inside the folder and run the commands:
我从这里下载了.tar.gz该版本的包，解压它，移动到文件夹内并运行命令：1.8.0
python setup.py build --fcompiler=gnu95
python setup.py install --user
as described in the user guideand in this question: Building NumPy 1.7.1 on Ubuntu.
如用户指南和此问题中所述：在 Ubuntu 上构建 NumPy 1.7.1。
This resulted in NumPyno longer loading in Spyder, which now shows the error:
这导致NumPy不再加载 in Spyder，现在显示错误：

upon loading it. The same happened when I tried with version 1.7.1.
加载后。当我尝试使用 version 时发生了同样的情况1.7.1。
I tried removing numpywith:
我尝试删除numpy：
sudo apt-get remove python-numpy
which also removed matplotliband scipy. So then I tried reinstalling them with:
这也删除了matplotlib和scipy。然后我尝试重新安装它们：
sudo apt-get install python-numpy python-scipy python-matplotlib
but this fails with the error:
但这失败并出现错误：
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
Now I'm left with no running python and I don't even know how to go back to the previous stable version. So the question: can I install at least version 1.7.1in my system and if not, how do I go back to a working 1.6.0version? Thanks.
现在我没有运行 python，我什至不知道如何回到以前的稳定版本。所以问题是：我可以1.7.1在我的系统中安装至少一个版本，如果没有，我如何回到工作1.6.0版本？谢谢。

sudo pip install numpy --upgrade
will do the same thing with slightly less effort.
会以更少的努力做同样的事情。

Ok, so I tried:
好的，所以我试过：
pip uninstall numpy
which returned:
返回：
Successfully uninstalled numpy
So then I did:
然后我做了：
pip install numpy
but it said:
但它说：
Requirement already satisfied (use --upgrade to upgrade): numpy in /home/gabriel/.local/lib/python2.7/site-packages
Cleaning up...
so apparently it was still there. I removed the contents of that folder and then I simply did:
所以显然它还在那里。我删除了该文件夹的内容，然后我只是做了：
sudo pip install numpy
This worked like freaking magic. Now I have NumPy 1.8.0, SciPy 0.12.0, Matplotlib 1.2.1installed and everything is running like it should.
这就像该死的魔法。现在我已经NumPy 1.8.0, SciPy 0.12.0, Matplotlib 1.2.1安装了，一切都像它应该的那样运行。
