PIP Install Numpy throws an error "ascii codec can't decode byte 0xe2"
提问by Josh.F
I have a freshly installed Ubuntu on a freshly built computer. I just installed python-pip using apt-get. Now when I try to pip install Numpy and Pandas, it gives the following error.
我在一台新造的电脑上安装了一个新安装的 Ubuntu。我刚刚使用 apt-get 安装了 python-pip。现在，当我尝试 pip install Numpy 和 Pandas 时，出现以下错误。
I've seen this error mentioned in quite a few places on SO and Google, but I haven't been able to find a solution. Some people mention it's a bug, some threads are just dead... What's going on?
我在 SO 和 Google 上的很多地方都看到了这个错误，但我一直找不到解决方案。有些人提到这是一个错误，有些线程已经死了……这是怎么回事？

I had this exact problem recently and used
我最近遇到了这个确切的问题并使用了
apt-get install python-numpy
This adds numpy to your system python interpreter. I may have had to do the same for matplotlib. To use in a virtualenv, you have to create your environment using the
这将 numpy 添加到您的系统 python 解释器中。我可能不得不为 matplotlib 做同样的事情。要在 virtualenv 中使用，您必须使用
--system-site-packages
option
选项

In 'site-packages' directory, make 'sitecustomize.py' like this
在“site-packages”目录中，像这样制作“sitecustomize.py”
import sys
sys.setdefaultencoding("utf-8")
Now you can get the file 'pip.log'
现在你可以得到文件'pip.log'

I had a similar error when running pip install pandasand it was due to a memory shortage. I increased the memory in my virtual machine to 4G and that fixed things.
我在运行时遇到了类似的错误pip install pandas，这是由于内存不足造成的。我将虚拟机中的内存增加到 4G 并解决了问题。

For me @Charles Duffy comment solved it. Put this in your env:
对我来说，@Charles Duffy 评论解决了这个问题。把它放在你的环境中：
LC_ALL=C
LC_ALL=C
You can add it to your .bashrc with a line like this:
您可以使用如下一行将其添加到 .bashrc 中：
export LC_ALL=C
export LC_ALL=C
But take in care that you'll affect all other programs. So you may want to use it just for the pip run:
但请注意，您会影响所有其他程序。因此，您可能只想将它用于 pip 运行：
$ LC_ALL=C pip install ...
$ LC_ALL=C pip install ...

If you want the pip version of numpy, you can build the dependencies for the package and then install it using pip
如果你想要 numpy 的 pip 版本，你可以构建包的依赖项，然后使用 pip 安装它
sudo apt-get build-dep python-numpy
pip install numpy
This should install everything needed at system level to install the package.
这应该安装在系统级别安装软件包所需的一切。

For me this was solved by ignoring a (presumably) corrupted cache with
