(-aAa-) Linux，预制二进制文件 的 3 种安装方法 (***)
Just 用户指南 https://just.systems/man/zh/%E9%
方法一：
export PATH=$PATH:/path-to-justsource ~/.bashrc方法二：自行制作 appimage
## 参考：指向 AppRun # 在 Shell 搜索可执行文件的路径中添加`~/bin` # 这一行应该被添加到你的 Shell 初始化文件中，e.g. `~/.bashrc` 或者 `~/.zshrc`： export PATH="$PATH:$HOME/bin"方法三： 预制二进制文件 ************
> https://just.systems/man/zh/%E9%
Linux、MacOS 和 Windows 的预制二进制文件可以在 发布页 上找到。
你也可以在 Linux、MacOS 或 Windows 上使用下面的命令来下载最新的版本，只需将 DEST 替换为你想安装 just 的目录即可：
curl --proto '=https' --tlsv1.2 -sSf https://just.systems/install.sh | bash -s -- --to DEST例如，安装 just 到 ~/bin 目录：
# 创建 ~/bin mkdir -p ~/bin # 下载并解压 just 到 ~/bin/just curl --proto '=https' --tlsv1.2 -sSf https://just.systems/install.sh | bash -s -- --to ~/bin # 在 Shell 搜索可执行文件的路径中添加`~/bin` # 这一行应该被添加到你的 Shell 初始化文件中，e.g. `~/.bashrc` 或者 `~/.zshrc`： export PATH="$PATH:$HOME/bin" # 现在 just 应该就可以执行了 just --help> https://just.systems/install.sh
