Zsh 安装步骤教程

VirtualBox 安装 debian 7.8.0
官网下载 Zsh 5.0.7
解压缩，进入 root 状态

./configure，报错

No terminal handling library was found on your system. This is probably a library called 'curses' or 'ncurses'. You may need to install a package called 'curses-devel' or 'ncurses-devel' on your system.

找到解决方案，使用'libncurses5-dev'替代'ncurses-devel'
```
apt-get install libncurses5-dev
```
安装
```
./configure
make
make install
```

安装'oh-my-zsh', 'install.sh'被下载到当前目录

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh
sh install.sh

上一步报错发现没装'git'，先装上再运行就没有问题了
```
apt-get install git
```

想把 zsh 作为默认 shell，报错

whereis zsh
chsh -s /usr/local/bin/zsh
> chsh: /usr/local/bin/zsh is an invalid shell

查了一下，chsh修改的是/etc/passwd，而这个报错是由于'zsh'没有登记，在/etc/shells里登记
好了，再运行chsh没有报错了，重启生效——注意是重启电脑
