anaconda

two install failure because of bad install package, may be because the package in the tsinghua mirror is updating, 
anyway I should see the package more clearly and persist to download them from tsinghua mirror.

the pipeline of installation of Anaconda3 of linux version from tsinghua mirror
1. download the package named Anaconda3-2019.10-Linux-x86_64.sh in the tsinghua mirror
2. copy the package in the host machine to the virtual machine
3. bash ~/Anaconda3-2019.10-Linux-x86_64.sh
4. Enter (begin)
5. Enter yes (accept terms. It will let you reinput if you directly Enter)
6. Enter (accept installation directory)
7. Enter yes (to run init.py including modifying ~/.bashrc)
8. source ~/.bashrc
9. copy vimrc in the host machine to the virtual machine
