第一次启动supervisor的时候报这个错，是下载源的问题吗？

[hadoop@jl-master minos-master]$ ./build.sh start supervisor --tank_ip 172.16.8.1 --tank_port 8000 2014-11-24 11:48:58 Building supervisor 2014-11-24 11:48:58 Check and install prerequisite python libraries 2014-11-24 11:48:58 Installing elementtree Downloading/unpacking elementtree>=1.2.6-20050316 Could not find any downloads that satisfy the requirement elementtree>=1.2.6-20050316 Some externally hosted files were ignored (use --allow-external elementtree to allow).

嗯，是下载源时出问题了，如果一直不好用，可以先手动下载这个包，然后离线装一下：

$Minos_root/build/env/bin/pip install elementtree --no-index --find-links $elementtree_tarball_path/elementtree-xx.xx.tar.gz

然后再启动
