Configuring Vim and Nerdtree Plugins

Recently you've been learning to develop Ruby using the Vim editor. Follow the online tutorial to install VIM. The address of the official website is difficult to download. Use

sudo Install VIM-GTK

The first download does not come down, later I think I was the last time I installed Ruby said source.list file changed, to become the source of NetEase.
or restore it back. Use the original source. The file I'm talking about is/etc/apt/source.list.

The next installment is going well.

You can then enter VIM or Gvim to open the Vim editor. Then downloaded the Vim nerdtree plugin. Follow the online approach to first

git clone https://github.com/scrooloose/nerdtree

Then build the ~/.vim/plugin and ~/.vim/doc directories. Copy the Plugin/nerd_tree.vim and Doc/nerd_tree.txt to the ~/.vim/plugin and ~/.vim/doc directories respectively.
Then you can enter it after Vim starts: Nerdtree to bring up the tree directory. There was an error in my case:

It turns out that I installed the plugin in the plugin directory. In fact, it should be said that other files in the Nerdtree folder overwrite the installation in the Vim73 folder.

Finally ushered in an important moment, the installation was successful!
