python安装pillow时出错（ubuntu）

apt-get install libjpeg8 libjpeg62-dev libfreetype6 libfreetype6-dev python-dev

在执行此命令时可能会遇到找不到包的问题，是因为更换源的原因，我是将源更换为了阿里的镜像，虽然速度变快了，但是会遇到找不到安装包的错误，此时的处理方法是将镜像源换回原来的，执行以下命令：

mv /etc/apt/sources.list{,.bak}
vim /etc/apt/sources.list

在打开的编辑器中输入以下网址：

deb http://us.archive.ubuntu.com/ubuntu/ trusty main restricted
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty main restricted
deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted
deb http://us.archive.ubuntu.com/ubuntu/ trusty universe
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty universe
deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates universe
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-updates universe
deb http://us.archive.ubuntu.com/ubuntu/ trusty multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-updates multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu trusty-security main restricted
deb-src http://security.ubuntu.com/ubuntu trusty-security main restricted
deb http://security.ubuntu.com/ubuntu trusty-security universe
deb-src http://security.ubuntu.com/ubuntu trusty-security universe
deb http://security.ubuntu.com/ubuntu trusty-security multiverse
deb-src http://security.ubuntu.com/ubuntu trusty-security multiverse

然后保存退出并执行以下命令更新：

apt-get update

更新完成之后，再次执行命令：

apt-get install libjpeg8 libjpeg62-dev libfreetype6 libfreetype6-dev python-dev

最后执行命令安装pillow即可：

pip install pillow
