Install the YouCompleMe plug-in Vim in Ubuntu 14.04

Install the YouCompleMe plug-in Vim in Ubuntu 14.04

For the most authoritative original steps, refer to README. md of this plug-in github. If time permits, read the plug-in several times as much as possible to avoid unnecessary troubles.

Version Check. Generally, all new systems are satisfied. Ensure that Vim> = 7.3.584. Support for python.

Step 1: Download The Vundle and YouCompleteMe plug-ins

Enter the following command to download Vundle

git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim

After the download is successful, modify the. vimrc file under the user root directory and append the following statement:

set nocompatiblefiletype offset rtp+=~/.vim/bundle/Vundle.vimcall vundle#begin()Plugin 'gmarik/Vundle.vim'Plugin 'Valloric/YouCompleteMe'call vundle#end()filetype plugin indent on

Run Esc in vim and run the following command to install the plug-in:

:PluginInstall

Or enter:

vim +PluginInstall +qall

Step 2: download other necessary files

• Download the latest version of LLVM

We strongly recommend that you download the compiled second-level file package. If you download the source file and compile it yourself, you will never know what will happen.

Decompress the package to the specified folder. The process is as follows:

cd ~mkdir ycm_tempcd ycm_tempxz -d clang+llvm-3.6.0-x86_64-linux-gnu-Ubuntu-14.04.tar.xztar -xvf clang+llvm-3.6.0-x86_64-linux-gnu-ubuntu-14.04.tar

Change the name of the clang + llvm-3.6.0-x86_64-linux-gnu folder to llvm_root_dir

• Download the latest cmake version.

We strongly recommend that you download the compiled second-level file package. If you download the source file and compile it yourself, you will never know what will happen.

Connect cmake to/usr/bin. For example, I put it under the Downloads folder, decompress it locally, and link it

tar zxvf cmake-3.2.2-Linux-x86_64.tar.gzln -s /home/li/Downloads/cmake-3.2.2/bin/cmake /usr/bin/cmake

Step 3: Compile the file

Run the following command to compile the file:

cd ~mkdir ycm_buildcd ycm_buildcmake -G "Unix Makefiles" -DPATH_TO_LLVM_ROOT=~/ycm_temp/llvm_root_dir . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cppmake ycm_support_libs 

In this way, the installation is basically complete.

Step 4: Configure vim

Although the installation and compilation are completed, it is still one step away from the success. You can configure vim (modify. vimrc) as needed. For example, my example is as follows:

Let g: ycm_global_ycm_extra_conf = '/home/li /. vim/bundle/YouCompleteMe /. ycm_extra_conf.pylet g: limit = 1 "syntax keyword completion let g: ycm_confirm_extra_conf = 0" When vim is enabled, you are not asked whether to load ycm_extra_conf.py to configure inoremap <expr> <CR> pum ()? "\ <C-y>": "\ <CR>" "press enter to select the current item set completeopt = longest, menu "makes Vim's completion menu Behavior consistent with general IDE (refer to VimTip1228)

Problems:

• E492: Not an editor command:

There are many possible causes. For example, I have encountered a permission issue, for the append write permission of. vim

• Cannot start normally, there are many red errors

There are also many possible causes. For example, I have encountered a problem that the compiler version is not suitable. For example, after gcc5.1.0 compilation and running is complete, I do not know why it is wrong.

• No. ycm_extra.conf.py File

You can refer to the file prepared by YCM to modify it or use it directly or mine (see the attachment ). Put it in the project root directory or specify a directory, such

$HOME/.vim/bundle/YouCompleteMe/.ycm_extra_conf.py

Of course, remember to modify the line in. vimrc!

• Other unknown errors
