我有一个 Vagrant 配置脚本，它会自动安装 Zsh（如果尚未安装），然后将 shell 更改为使用 Zsh。
我认为存在两个问题：
首先，我不认为 shell 已更改为 Zsh，因为当我运行 vagrant ssh 访问 Ubuntu 虚拟机并输入 ps -p $$ 命令时，该命令显示 Bash 是运行的 shell，而不是 Zsh（我原本期望应该是 Zsh）。
第二个问题是，如果它确实已更改为 Zsh shell （无论 ps -p $$ 返回了什么），那么当我 source .zshrc 文件时，Zsh 显示了许多错误，这些错误表明指定的函数缺失或者没有被正确引用。
我将分步骤进行说明，手动安装 Zsh 而不是通过 Vagrant 配置脚本...
cat /etc/shells-> 我看不到任何关于 Zsh† 的信息sudo apt-get updatesudo apt-get install zsh≠cat /etc/shells-> 现在有了/bin/zsh和/usr/bin/zshwhich zsh->/usr/bin/zshzsh --version->zsh 5.0.2 (x86_64-pc-linux-gnu)chsh -s $(which zsh)source .zshrc-> 很多错误信息被发送到 stdout~~tree /usr/share/zsh/-> 下面是输出，但是注意到function目录不在5.0.2目录中？
我认为更可能的情况是 Zsh 没有被更改，因为如果我执行命令 zsh，那么我将进入一个新的 shell 环境，如果我然后运行 source .zshrc，我将不会遇到任何错误。此外，如果我现在运行 ps -p $$，我将看到报告 Zsh 作为正在运行的 shell。
完整的 Vagrant 配置脚本可以在本问题底部找到。
† 我看到的 shell 列表如下:
/bin/sh
/bin/dash
/bin/bash
/bin/rbash
/usr/bin/tmux
/usr/bin/screen
