Linux中在zsh下如何安装autojump

介绍

autojump is a faster way to navigate your filesystem. It works by maintaining a database of the directories you use the most from the command line.
Directories must be visited first before they can be jumped to.

关于 autojump 有以下几个站点：
https://github.com/wting/autojump
https://github.com/haoziyeung/autojump
https://gitee.com/gentlecp/autojump/
https://www.worldlink.com.cn/en/osdir/autojump.html

注：autojump 不仅可以用在 zsh 环境下，也可以在 bash 环境下使用。

安装

cd ~/.oh-my-zsh/custom/plugins/ 
git clone git://github.com/wting/autojump.git
cd autojump
./install.py 

Linux 系统下执行 ./install.py 可能会提示下面的信息：

/usr/bin/env: “python”: 没有那个文件或目录

解决了 python 的问题后，执行脚本文件 ./install.py，结果如下：

Installing autojump to /root/.autojump ...
creating directory: /root/.autojump/bin
creating directory: /root/.autojump/share/man/man1
creating directory: /root/.autojump/etc/profile.d
creating directory: /root/.autojump/share/autojump
copying file: ./bin/autojump -> /root/.autojump/bin
copying file: ./bin/autojump_argparse.py -> /root/.autojump/bin
copying file: ./bin/autojump_data.py -> /root/.autojump/bin
copying file: ./bin/autojump_match.py -> /root/.autojump/bin
copying file: ./bin/autojump_utils.py -> /root/.autojump/bin
copying file: ./bin/icon.png -> /root/.autojump/share/autojump
copying file: ./docs/autojump.1 -> /root/.autojump/share/man/man1
creating directory: /root/.autojump/etc/profile.d
creating directory: /root/.autojump/share/autojump
creating directory: /root/.autojump/functions
copying file: ./bin/autojump.sh -> /root/.autojump/etc/profile.d
copying file: ./bin/autojump.bash -> /root/.autojump/share/autojump
copying file: ./bin/autojump.fish -> /root/.autojump/share/autojump
copying file: ./bin/autojump.zsh -> /root/.autojump/share/autojump
copying file: ./bin/_j -> /root/.autojump/functions

Please manually add the following line(s) to ~/.zshrc:
[[ -s /root/.autojump/etc/profile.d/autojump.sh ]] && source /root/.autojump/etc/profile.d/autojump.sh
autoload -U compinit && compinit -u

Please restart terminal(s) before running autojump.

如上所示，提示需要在文件 ~/.zshrc 手动添加如下命令语句：

[[ -s /root/.autojump/etc/profile.d/autojump.sh ]] && source /root/.autojump/etc/profile.d/autojump.sh
autoload -U compinit && compinit -u

保存修改后，在运行 autojump 之前需要重启终端。

注：我并没有在 ~/.zshrc 的 plugins=() 中添加 autojump，也可以正常使用。

安装有风险，我的Linux安装后直接崩溃掉，不知道为什么？安装后可以正常使用，退出终端后再重新进入就出现严重异常，根本无法正常使用：
