Oh My Zsh 是基于 zsh 命令行的一个扩展工具集，提供了丰富的扩展功能。

我的环境是安装的WSL2的Ubuntu20.04

下载安装zsh

首先点击这里下载最新的zsh源码

然后将源码包复制到/usr/local
cp /mnt/e/downloads/zsh-5.8.1.tar.xz /usr/local ##前面的/mnt/e/Downloads是指我的下载地址在E盘的downloads文件夹
tar xJvf zsh-5.8.1.tar.xz ##解压文件
cd zsh-5.8.1 ## 进入zsh文件夹
下面安装依赖，centos7用户使用yum命令
依赖有gcc、ncurses-dev
apt install gcc ncurses-dev -y
make && make install

设置默认shell

ps（默认装到/usr/lcoal/bin/zsh)

which zsh | sudo tee -a /etc/shells
sudo chsh -s /usr/local/bin/zsh

重新用windows terminal开个Ubuntu终端就能使用zsh了

安装Oh My Zsh

sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

安装插件

语法高亮插件zsh-syntax-highlighting

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting

自动补全插件 zsh-autosuggestions

git clone https://github.com/zsh-users/zsh-autosuggestions $ZSH_CUSTOM/plugins/zsh-autosuggestions

安装zsh-history-substring-search

git clone https://github.com/zsh-users/zsh-history-substring-search ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-history-substring-search

安装python3.9环境

wget https://www.python.org/ftp/python/3.9.9/Python-3.9.9.tgz
tar xzvf Python-3.9.9.tgz
cd Python-3.9.9
./configure prefix=/usr/local/python3 --enable-optimizations
make && make install

配置系统环境

# 删除之前的python3
whereis python
#(有风险)* rm -rf 所有python3的版本（除去/usr/local/python3） 
# 删除之前软连接
rm -rf /usr/bin/python
rm -rf /usr/bin/pip
# 添加新的链接
cp /usr/local/python3/lib/libpython3.9.a /usr/lib
echo "/usr/lib" > /etc/ld.so.conf.d/python3.9.conf
ldconfig
ln -s /usr/local/python3/bin/python3 /usr/bin/python
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip
# 添加环境变量
vi /etc/profile
#
# 添加 export PATH=$PATH:/usr/local/python3/bin
#
source /etc/profile

安装autojump

git clone git://github.com/joelthelion/autojump.git
cd autojump
./install.py
# 根据安装完成后的提示，在~/.zshrc最后添加下面语句：
vim ~/.zshrc    
[[ -s /root/.autojump/etc/profile.d/autojump.sh ]] && source /root/.autojump/etc/profile.d/autojump.sh

启用插件

#编辑~/.zshrc   
vim ~/.zshrc    
#找到plugins后括号里添加安装的插件名字
plugins=( git 
          autojump 
          zsh-autosuggestions 
          zsh-syntax-highlighting
          zsh-history-substring-search
          )
# 最后刷新
source ~/.zshrc
