[vim|macOS big sur|M1]vim配置環境踩坑記錄

vim安裝

根據https://github.com/ycm-core/YouCompleteMe 上的說法，在macOS上應該安裝支持Python的vim，而系統自帶的vim並不支持。
打開terminal，輸入

brew install vim

或者

brew install macvim

安裝完成后，可以通過

vim --version | grep python

來查看，如果有

+python3

則說明支持了python3

Vundle安裝YCM

這里不再贅述，可以網上沖浪github
之后在~./vimrc 中加入

Plugin 'Valloric/YouCompleteMe'

Normal模式下

:PluginInstall

耐心等待一會，顯示Done時為安裝完成。

配置環境

brew install cmake mono go nodejs
brew install java
sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

這里Python3建議手動安裝 3.8

編繹安裝

cd ~/.vim/bundle/YouCompleteMe
python3 install.py --all

我這里報錯了，很絕望了。然后又在同目錄下發現一個install.sh，成功了，建議先用：

./install.sh

C

./install --clangd-completer

但：

掛上Proxy后好了，但下載clangd的時候：

Downloading Clangd from https://github.com/ycm-core/llvm/releases/download/12.0.0/clangd-12.0.0-x86_64-apple-darwin.tar.bz2...

During handling of the above exception, another exception occurred:

這是Python3的urllib的鍋，掛代理后ssl證書不信任，我找到源文件，在import部分末尾加上：

import ssl                                                                      
ssl._create_default_https_context = ssl._create_unverified_context

終於：

Clangd completer enabled. If you are using .ycm_extra_conf.py files, make sure they use Settings() instead of the old and deprecated FlagsForFile().

Go

./install.py --go-completer

但有反爬機制：

先在開頭導入requests：

import requests

在135行，改為：

def DownloadFileTo( download_url, file_path ):                                  
	headers = {'User-Agent': 'User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36 (KHTML, like Geck) Chrome/56.0.2924.87 Safari/537.36'}
  # with urllib.request.urlopen( download_url , headers=headers ) as response:  
    # with open( file_path, 'wb' ) as package_file:                             
        # package_file.write( response.read() )                                   
  res = requests.get(download_url, headers)                                     
  with open(file_path, 'wb') as package_file:                                   
    package_file.write(res.content)

java

./install.py --java-completer

其他

C#, Rust, JavaScript...

./install.py --cs-completer --rust-completer --ts-completer

或安裝全部：

./install.py --all
