使用 nix 定义的 tmux 插件会导致 127 个错误

Question

概述

我正在尝试在 macOS 上使用 nix 和 home-manager 设置 tmux。

但是，每当我刷新 tmux 配置时，都会收到以下错误：

'/nix/store/6iq9z3wnacxqhja3r93b7lsdl1kvcp11-tmuxplugin-sensible-unstable-2017-09-05/share/tmux-plugins/sensible/sensible.tmux' returned 127                                                                                                                            [0/0]

调试

我查看了生成的

tmux.conf

文件，发现有几个

run-shell

命令，如下所示：

# ============================================= #
# Start with defaults from the Sensible plugin  #
# --------------------------------------------- #
run-shell /nix/store/6iq9z3wnacxqhja3r93b7lsdl1kvcp11-tmuxplugin-sensible-unstable-2017-09-05/share/tmux-plugins/sensible/sensible.tmux
# ============================================= #

这些

run-shell

命令与 tmux 日志中存在 127 个错误的程序相匹配。

根据这个GitHub问题，127错误意味着找不到程序。然而，当我明确尝试运行这些程序或

cat

它们时，我看到了它们。

所以这告诉我，由于某种原因我可以手动运行生成的程序，但 tmux 不能。

我找到了这篇文章：tmux run Fish shell 函数返回错误 127。因此，我还尝试使用

.tmux

运行生成的

/bin/sh

程序，并且可以在那里成功运行它们。

这是我的 tmux 的整个 nix 配置。

听起来像是您用来启动 tmux 会话的 shell 环境的问题。如果您使用其他程序（例如 kitty）自动启动 tmux 会话，请使用交互式登录 shell 来启动它。类似的东西

${pkgs.zsh}/bin/zsh -l -i -c "${pkgs.tmux}/bin/tmux new-session -s local-tmux-session"
