概述
仓颉编程语言是一款面向全场景智能的新一代编程语言，主打原生智能化、天生全场景、高性能、强安全。主要应用于鸿蒙原生应用及服务应用等场景中，为开发者提供良好的编程体验。
今天，我们介绍一下仓颉语言在Linux mint 22.1上的安装。
下载
考虑到截止目前为止还没有一个可用的长期稳定版本，所以，我们这里下载半年更新版。
对于PC电脑来说，目前基本上都是x64架构，也称为AMD64架构，所以，我们选择下载Cangjie-0.53.18-linux_x64.tar.gz。
解压
下载结束以后，我们将其解压到用户目录下的目录.cangjie中。
bash
tar -zxvf Cangjie-0.53.18-linux_x64.tar.gz
mv cangjie ~/.cangjie配置
解压后的目录结构如下：
bash
lwk@qwfys:~$ ll .cangjie/
total 48
drwxr-x--- 8 lwk lwk 4096 Mar 16 18:10 ./
drwxr-x--- 38 lwk lwk 4096 Mar 16 18:30 ../
drwxr-x--- 2 lwk lwk 4096 Feb 28 2023 bin/
-rwxr-x--- 1 lwk lwk 1458 Feb 28 2023 envsetup.sh*
drwxr-x--- 4 lwk lwk 4096 Feb 28 2023 lib/
drwxr-x--- 4 lwk lwk 4096 Feb 28 2023 modules/
-rwxr-x--- 1 lwk lwk 9078 Feb 28 2023 README.md*
drwxr-x--- 3 lwk lwk 4096 Feb 28 2023 runtime/
drwxr-x--- 4 lwk lwk 4096 Feb 28 2023 third_party/
drwxr-x--- 5 lwk lwk 4096 Feb 28 2023 tools/
lwk@qwfys:~$envsetup.sh是一个环境变量初始化脚本，执行命令
bash
source ~/.cangjie/envsetup.sh以后，在当前会话中，就可以正常使用仓颉的命令行工具了。
为方便每次登录账号以后，系统都能自动帮我们完成仓颉语言环境变量的初始化工作，我们其添加到用户目录的.bashrc文件的末尾。命令如下：
bash
tee -a ~/.bashrc <<-EOF
export CANGJIE_DIR="$HOME/.cangjie"
[[ -s "$HOME/.cangjie/envsetup.sh" ]] && source "$HOME/.cangjie/envsetup.sh"
EOF查看
通过上述配置，我们退出当前账号，重新登录一次，就可以正常使用了。

lwk@qwfys:~$小结
今天我们带领大家完成了仓颉语言运行时环境的在Linux mint 22.1上的安装。以下几点，大家需要着重注意：
- 版本
从实践角度来说，我们在生产环境始终需要注意的就是安装长期维护版，即LTS。由于截止目前为止，LTS还没有发布，所以这时暂且安装半年维护版。
- cjpm
仓颉语言提供了仓颉包管理工具cjpm，日后，关于仓颉包管理就可以借助它管理起来。这个包管理工具日后与npm、pip、canda是类似的。
