pip安装scipy.0.18出现的问题

---

本文解决两个问题：
安装pip8.1.1后无法升级至9.0.1和scipy.0.18.whl is not a supported wheel on this platform

使用pip安装下载好的scipy.0.18.whl

pip install scipy.0.18.whl

报错：
scipy.0.18.whl is not a supported wheel on this platform
我以为是pip的不兼容，于是升级了pip

sudo pip install –upgrade

升级失败
于是手动下载了pip-9.0.1.tar.gz

tar -zxvf pip-9.0.1.tar.gz
cd pip-9.0.1
sudo python setup.py install
sudo pip install scipy.0.18.whl

报错：

问题没有解决，而且还因为升级了pip9.0.1出现了新的问题
针对pip安装出现

The directory '/home/x/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

网上的解决办法是

sudo -H pip install…

这个时候查看pip版本还是8.1.1,在/home/mt/anaconda2/bin目录下，有个easy_install-2.7,输入命令easy_install-2.7 pip==9.0.1,成功将版本变为了9.0.1

由于我的python是用Anaconda安装的，所以直接使用conda升级scipy是最简单最有效的办法

conda update scipy

等到升级完就成功安装了scipy.0.18
