2024年6月21日，华为仓颉正式公开发布。
不少同学看过仓颉白皮书后，都在找SDK从哪下载，HelloWorld怎么跑。仓颉公众号也及时发布了内测的方式，我也亲自走了一遍整个流程，
一，申请内测
关注“仓颉编程语言”微信公众号，回复“SDK”关键词，填写内测申请问卷（姓名、邮箱、gitcode地址等）。【建议提前注册gitcode，github可直接授权登录】
接下来就是等待邮件回复，2-3个工作日，
管理审核成功后，即可访问仓颉社区：仓颉SDKGitCode是面向全球开发者的开源社区,包括原创博客,开源代码托管,代码协作,项目管理等。与开发者社区互动,提升您的研发效率和质量。
https://gitcode.com/Cangjie 仓颉支持VSCode开发环境，社区提供了VSCode插件CangjieVSCodePlugin，以及Linux/Windows/MacOS版本的SDK。
二，环境搭建
2.1 Windows平台搭建仓颉环境
2.1.1 下载SDK
从你送到的邮箱里面点击Windows版本的仓颉lSDK链接
点击exe或者 zip都行，exe需要安装，zip解压可用
我这里用的zip，直接解压
2.1.2 安装，配置系统环境
2.1.2.1 exe安装
如果你下载的SDK是exe格式，直接点击安装就好，安装时会自动将所需环境变量配置好。
选 all user
2.1.2.2 zip 解压 配置环境变量
我这里的解压到 E:\cangjie\cangjieSDK\
右键 我的电脑---->属性---->高级系统设置---->环境变量
然后找到下方 系统变量---->双击Path
将
E:\cangjie\cangjieSDK\bin
E:\cangjie\cangjieSDK\tools\bin
添加到环境变量
遇到环境变量超过2047 请参考《解决：此环境变量太大。此对话框允许将值设置为最长2047个字符-CSDN博客》

汉字编码有问题，我们后面学习在研究，先换成英文的试试
main() {
println("hello cangjie")
}
