1. 编译安装python
1.1 下载 python 源代码
$wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
$tar -zxvf Python-3.6.5.tgz; cd Python-3.6.5/1.2 安装 zlib 相关依赖
$sudo yum -y install zlib*1.3 配置生成 makefile
$./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" --enable-unicode=ucs4 --enable-optimizations1.4 编译安装 python
$make
$sudo make altinstall
$sudo ln -sv /usr/local/bin/python3.6 /usr/local/bin/python
$sudo unlink /usr/bin/python; sudo ln -sv /usr/local/bin/python /usr/bin/python
$sudo unlink /home/tops/bin/python; sudo ln -sv /usr/local/bin/python /home/tops/bin/python 升级 python 之后可能会因为语法不一致导致依赖于旧版本 python 的软件工作不正常
例如运行 yum 可能会出现如下错误
$ yum
File "/usr/bin/yum", line 30
except KeyboardInterrupt, e:
SyntaxError: invalid syntax 解决的办法：
1. 升级 yum
2. 或者修改 yum 使用的语法解释器
修改 #!/usr/bin/python 为 #!/usr/bin/python2.7
3. 在编译VIM之后把 /home/tops/bin/python 软连接回 python2.7
#Sctipt to switch to python 3
$cat ~/rain/p3.sh
sudo unlink /home/tops/bin/python
sudo ln -sv /usr/local/bin/python /home/tops/bin/python
ls -al /home/tops/bin/python
sudo unlink /usr/bin/python•
sudo ln -sv /usr/local/bin/python /usr/bin/python•
ls -al /usr/bin/python
#################################
#Sctipt to switch to python 2
$cat ~/rain/p2.sh
sudo mv /home/tops/bin/python /home/tops/bin/python-bak
sudo ln -sv /home/tops/bin/python2 /home/tops/bin/python
ls -al /home/tops/bin/python
sudo mv /usr/bin/python /usr/bin/python-bak•
sudo ln -sv /usr/bin/python2 /usr/bin/python•
ls -al /usr/bin/python2. 编译安装VIM
2.1 安装相关依赖，如果可以直接安装 python可以省去前面编译过程
$sudo yum install lua lua-devel –y
$sudo yum install ncurses-devel
$sudo yum install -y ruby ruby-devel lua lua-devel luajit uajit-devel ctags git python python-devel python3 python3-devel tcl-devel perl perl-devel perl-ExtUtils-ParseXS perl-ExtUtils-XSpp perl-ExtUtils-CBuilder perl-ExtUtils-Embed2.2 删除存在的 VIM
sudo yum remove vim vim-runtime gvim2.3 克隆 VIM 源代码
$git clone https://github.com/vim/vim.git; cd vim2.4 配置生成 makefile
$./configure --enable-multibyte --enable-perlinterp=yes --enable-rubyinterp=yes --enable-python3interp=yes --enable-luainterp=yes --enable-gui=auto --enable-cscope --disable-selinux --with-features=huge --prefix=/usr/local如果编译之后的 VIM 版本信息里面不包含 +python3，可以尝试添加 Python3 配置路径
--with-python3-config-dir=/usr/local/lib/python3.6/config-3.6m-x86_64-linux-gnupython路径需要改成实际路径
2.5 编译安装VIM 到 /usr/local/share/vim/vim80
make VIMRUNTIMEDIR=/usr/local/share/vim/vim80
sudo make install3 配置 VIM
3.1 安装配置 spf13 (refer to https://github.com/spf13/spf13-vim)
curl https://j.mp/spf13-vim3 -L > spf13-vim.sh && sh spf13-vim.sh 安装后会创建 ~/.spf13-vim-3 目录，对于 VIM 的配置基本上只需要涉及如下文件
1. ~/.vimrc.before.local 自定义配置，spf13 加载 .vimrc 之后被读取
2. ~/.vimrc.bundles.local 自定义安装插件配置
如果前面安装的时候没有指定 VIM 的运行时路径可以在 ~/.vimrc.before.local 里面添加
let $VIMRUNTIME=”/usr/local/share/vim/vim80”
解决拼写错误 “Warning: Cannot find word list "en.utf-8.spl" or "en.ascii.spl"”
运行 VIM 并执行 :echo substitute(&rtp, ',', '\n', 'g') 来检查 $VIMRUNTIME 是不是存在， 如果不存在于上述命令的结果，在 ~/.vimrc.before 里面添加
set rtp^=$VIMRUNTIME
设置拷贝内容到系统剪切板，在 ~/.vimrc.before 里面添加
set copy to clipboard
set clipboard=unnamedplus
设置 VIM 配色主题，在 ~/.vimrc.before.local 或者 ~/.vimrc.local 里面添加
"colorscheme desert
"colorscheme gruvbox
"colorscheme molokai
"colorscheme solarized
"目前喜欢这个主题
colorscheme ron3.2 安装基于语义的自动补全插件 YouCompleteMe (refer to https://github.com/Valloric/YouCompleteMe)
用 VIM 打开 ~/.vimrc.before.local 并添加
let g:spf13_bundle_groups=['general', 'programming', 'misc', 'scala', 'youcompleteme']
在打开的VIM里执行命令更新插件，会自动安装YouCompleteMe
:w
:RundleInstall
:wq3.2.1 Troubleshooting
YouCompleteMe unavailable no module named frozendict( or future)。
【原因】
YCM 依赖的安装包没有成功安装，一般是网速不佳，下载出错，或者中途人为退出。
【解决方法】
手工安装。 例如
$sudo pip3 install future或者通过 GIT 重新克隆依赖的库之后再安装
$cd ~/.vim/bundle/YouCompleteMe/; git submodule update --init --recursive; vim +BundleInstall3.2.2 安装 cmake
YouCompleteMe 用 cmake 编译代码来分析依赖关系，并提示可能的语法错误
yum install cmake 或者下载源代码编译安装
https://www.atatech.org/articles/105727
3.2.3 编译YouCompleteMe，相当于生成符号的数据库 ycm_core.so
$cd ~/.vim/bundle/YouCompleteMe; ./install.py --clang-completer --enable-coverage --enable-debug3.2.4 配置对 C/C++ (clang) 代码的自动补全
设置代码补全的搜索路径，可以添加其他目录
$sudo mkdir -p -m 777 ~/.vim/data/ycm
$cp ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py ~/.vim/data/ycm/
$vim ~/.vim/data/ycm/.ycm_extra_conf.py
# [Rain] Additional include path
'-isystem', '/usr/include',
'-isystem', '/usr/local/include',
'-isystem', '/usr/include/c++/4.8.5',
'-I', '/usr/src/kernels/3.10.0-327.ali2010.alios7.x86_64/include'3.2.5 启动 VIM 时自动加载 YCM，在 ~/.vimrc.before.local 里添加
let g:acp_enableAtStartup = 13.2.6 设置额外查找路径的 python 脚本路径
" global conf which is needed to resolve name in system include
" file or other third-part include file
let g:ycm_global_ycm_extra_conf='~/.vim/data/ycm/.ycm_extra_conf.py'3.2.7 允许使用tags来进行补全
"enable completion from tags
let g:ycm_collect_identifiers_from_tags_files = 1
let g:ycm_seed_identifiers_with_syntax = 1
let g:ycm_confirm_extra_conf = 0
let g:ycm_cache_omnifunc=0
let g:ycm_key_invoke_completion = '<C-;>'3.2.8 Troubleshooting
- Can't jump to definition
在 VIM 里执行命令
: YcmDiag把提示的头文件的目录添加到~/.vim/data/ycm/.ycm_extra_conf.py
3.4 配置 VIM-Airline
3.4.1 MaxOS 安装 PowerLine 字体，否则状态栏会出现乱码
# Install powerline font on MaxOS
$cd ~/.vim/bundle/fonts; ./install.sh3.4.2 更改 iterm2 文本字体
通过快捷键Command+, 或者菜单（iterm2 -> Preferences）打开首选项->profile->text->Change Fonts，选择以 for powerline 结尾的字体。
3.4 设置快捷键
设置快捷键 F5 更新依赖关系，也就是用cmake编译代码
nnoremap <F5> :YcmForceCompileAndDiagnostics<CR>
设置快捷键 F12 跳转声明和定义以及打开包含的头文件
nnoremap <F12> :YcmCompleter GoToDefinitionElseDeclaration<CR>3.10 安装、删除插件
echo Bundle \'Plugin Name\' >> ~/.vimrc.bundles.local
例如安装vim官网的 grep 插件，我们可以使用
echo Bundle \‘vim-scripts/grep.vim\' >> ~/.vimrc.bundles.local
添加之后使用如下命令来安装
vim +BundleInstall! +BundleClean +q
如果已经打开了 VIM 可以直接执行命令
:BundleInstall
删除已经安装的插件
echo UnBundle \'Plugin Name\' >> ~/.vimrc.bundles.local
执行删除插件的命令
vim +BundleClean +q
如果已经打开了 VIM 可以直接执行命令
:BundleClean
例如删除 vim官网的 grep 插件，我们可以使用
echo UnBundle \‘vim-scripts/grep.vim\' >> ~/.vimrc.bundles.local3.11 自定义 VIM 颜色主题
可以访问 http://bytefluent.com/vivify/
保存颜色主题文件到本地之后拷贝到 VIM 颜色主题目录，然后更改 ~\.vimrc.local
$cp rain.vim to ~\.vim\colors
$echo colorscheme rain >> ~\.vimrc.local
设置对.vimrc的更改立即生效
echo autocmd BufWritePost $MYVIMRC source $MYVIMRC >> .vimrc.before.local 3.12 VIM 效果
