Ubuntu Zsh（通过 Vagrant）没有找到 Zsh 或其功能

Question

我有一个 Vagrant 配置脚本，如果 Zsh 不可用，它会尝试安装它，然后更改 shell 以使用 Zsh。

我认为我遇到了两个问题：

首先我不相信 shell 会更改为 Zsh，因为当我运行 vagrant ssh 访问 Ubuntu VM 并且一旦运行 ps -p $$ 命令表明 Bash 是正在运行的 shell（我会在那里预期 Zsh）。

第二个问题是，如果它 正在 更改为 Zsh shell（不管 ps -p $$ 报告什么），那么当我获取 .zshrc 文件时，Zsh 会显示很多错误，这表明指定的函数丢失或没有正确引用。

---

我将通过手动安装 Zsh 而不是通过 Vagrant 配置脚本将其分解为多个步骤...

1. cat /etc/shells -> 我看不到对 Zsh 的引用†
2. sudo apt-get update
3. sudo apt-get install zsh≠
4. cat /etc/shells -> 现在有 /bin/zsh 和 /usr/bin/zsh
5. which zsh -> /usr/bin/zsh
6. zsh --version -> zsh 5.0.2 (x86_64-pc-linux-gnu)
7. chsh -s $(which zsh)
8. source .zshrc -> 很多错误发送到标准输出~~
9. tree /usr/share/zsh/ -> 见下文** 输出，但请注意 function 目录不在 5.0.2 目录中？

我认为 Zsh 更有可能没有被更改，因为如果我执行命令 zsh 我会被带到一个新的 shell 环境，如果我然后运行 ​​source .zshrc 我不会收到任何错误。另外，如果我现在运行ps -p $$，我会看到 Zsh 被报告为正在运行的 shell。

我的整个 Vagrant 配置脚本可以在这个问题的底部找到。

† 我看到的 shell 列表是：

/bin/sh
/bin/dash
/bin/bash
/bin/rbash
/usr/bin/tmux
/usr/bin/screen

这是我的 Vagrant 配置脚本

# Install dependencies
add-apt-repository ppa:pi-rho/dev # for latest tmux
apt-get update
apt-get remove vim-tiny -y
apt-get install vim tmux git tree htop reptyr xclip -y

# Install Zsh shell if it's not available
if ! cat /etc/shells | grep zsh; then
  echo "Zsh is not available, so we'll install it now"
  apt-get install zsh -y
fi

# For the Reptyr program to work we need to enable system access
# We do this by changing the ptrace scope from one to zero
sed -i 's/kernel.yama.ptrace_scope = 1/kernel.yama.ptrace_scope = 0/' /etc/sysctl.d/10-ptrace.conf

# Because this is a system control daemon, we need to restart the relevant service
sysctl -p /etc/sysctl.d/10-ptrace.conf

# Avoid the shell asking us to authorise the authenticity of github.com
# This happens when doing a git clone for the first time
echo -e "Host github.com\n\tStrictHostKeyChecking no\n" >> ~/.ssh/config

# Install dotfiles...
dotfiles_location=/home/vagrant/dotfiles
git clone https://github.com/Integralist/dotfiles.git $dotfiles_location
cd $dotfiles_location && git fetch && git checkout linux

# Ensure we don't move unnecessary files
shopt -s extglob
mv !(.|..|.git|README.md) ..

# Clean-up
cd ../ && rm -rf dotfiles

# Change to Zsh shell
chsh -s $(which zsh)

# Source the Zsh config file
source .zshrc

Answer 1

chsh 仅更改当前用户的默认/登录 shell，它不会更改 当前 shell。

您要么需要注销并重新登录，要么手动 exec zsh 更改活动/当前 shell。
