 ./configure --with-ssl --prefix=/usr/local/python3

zipimport.ZipImportError: can't decompress data; zlib not available
Makefile:1079: recipe for target 'install' failed
make: *** [install] Error 1

解决办法：安装依赖

1 sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev 
2 libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev 
3 xz-utils tk-dev

sudo apt-get install build-essential
sudo apt-get install python3-dev
sudo apt-get install libxml2-de;
sudo apt-get install libxslt1-dev
sudo apt-get install libssl-dev
apt-get install -y libffi-dev

安装一个python3.6.6，终于可以pip3下载了。

ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

sudo vim /usr/bin/lsb_release

修改第一行，指明python的版本号，若安装的是python3.6则修改：

#!/usr/bin/python3

为：

#!/usr/bin/python3.6

卸载了python3.4，导致没有终端，页面没有状态栏。   不要卸载

apt-get install nautilus-open-terminal

下面这个是重新安装桌面，可能会用到。重新安装桌面要startx启动。

sudo apt-get install ubuntu-minimal ubuntu-standard ubuntu-desktop
startx
