帮了个小忙，总结记录一下步骤，在chromebook上安装python
下载python开源版本Miniconda2安装文件
https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/Miniconda2-4.4.10-Linux-x86_64.sh
修改安装目录 /usr/local 的权限
sudo chmod a+rw /usr/local
执行安装
sh ~/Downloads/Miniconda2-4.4.10-Linux-x86_64.sh
注意选择安装目录为
/usr/local/miniconda2/
后续扩展
装完python，下一步想要装 notebook
conda install ipython ipython-notebook ipython-qtconsole
装完nodebook下一步是git，x86_64版本的系统，git下载地址如下
https://dl.bintray.com/chromebrew/chromebrew/git-2.17.0-chromeos-x86_64.tar.xz
安装git是从chromebrew的安装文件分拆出来的，install文件在github上有，略一分析，抽出git相关的部分
function extract_install () {
#extract and install
echo "Extracting $1 (this may take a while)..."
rm -rf ./usr
tar -xf $2
echo "Installing $1 (this may take a while)..."
tar cf - ./usr/* | (cd /; tar xp --keep-directory-symlink -f -)
mv ./dlist etc/crew/meta/$1.directorylist
mv ./filelist etc/crew/meta/$1.filelist
}
cd /usr/local/
mkdir etc/crew/meta/ -p
extract_install git git-2.17.0-chromeos-x86_64.tar.xz
git --version
