在vimfiles\plugin\ area中安装NERDTree.vim后，GVim会报告很多错误。
我得到了很多错误屏幕，第一个屏幕的前几个错误如下—
Error detected while processing .....vimfiles\plugin\NERD_tree.vim: line 4: E477: No ! allowed: <!DOCTYPE html> line 5: E488: Trailing characters: <html> line 6: E488: Trailing characters: <head> line 7: E488: Trailing characters: <meta charset='utf-8'> line 8: E488: Trailing characters: <meta http-equiv= line 9: E488: Trailing characters: <title>plugin/NERD_tree.vim at master from scrooloose/nerdtree - GitHub</title>
像@ZyX和@GWW说，看起来像你通过右键单击GitHub站点中save the link as ...获取nerdtree.vim文件，通过这种方式你有一个HTML页面。
在本页重新下载你的nerdtree.vim文件，单击NERD_tree.zip链接，解压缩并替换nerdtree.vim文件。
