You are using pip version 10.0.1, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Solution:
futures==3.2.0 => futures==3.1.1
2. Install Docker CE for Ubuntu

3. Problem:
write /var/lib/docker/tmp/GetImageBlob891597147: no space left on device
Solution:
sudo apt-get autoclean # 删除你已经卸载掉的软件包的命令为
sudo apt-get clean # 若你想清理出更多的空间，可以把电脑上存储的安装包全部卸载
sudo apt-get autoremove # 删除已经被卸载的软件所依赖的（其他软件不依赖的）孤立的软件包
空间仍不足：通过建立软链接将/var目录下占用空间较大的目录移动到富足的空间区块（如/home）下，使得/var下不再占用空间。 （具体实现）
mv /var/cache /home/lsy #将var下的cache目录移动到home或者其他空间富足的区块中
ln －s /home/lsy/cache /var #/var/cache指向/home/lsy/cache，这样cache目录将不再占用/var目录的空间
mv /var/lib/docker /home/lsy
ln -s /home/lsy/docker /var/lib
service docker stop
service docker start
一定要重启docker，否则会出现
