# install vim-go dependency pkgs to the default GOPATH '/root/go'

# 1. execute :GoInstallBinaries in vim editor manually
# 2. unpack the existing(if we already installed) go binaries
#    and dependency pkgs, copy it to the GOPATH
# the following function do it in the second way, but correctness
# can not be guaranteed.
# Note that vim-go need vim version greater than 8.1, we should
# install vim to /usr/bin from the source code as the following
# steps:
# 1. git clone https://github.com/newfriday/vim.git
# 2. cd vim
# 3. ./configure --with-features=huge --enable-pythoninterp --prefix /usr
# 4. make -j
# 5. make install
