看上去是因为 lcpkg.json 文件不存在而导致写入错误，你检查一下 LC GUI\LCUI-develop 目录里有没有 lcpkg.json 文件。

@lc-soft
检查了，有这个文件，但依旧存在问题。

从错误信息定位到的代码行来看，是因为 vcpkgRoot 无效。你没设置 vcpkg 目录吗？跑 lcpkg config vcpkg.root 看看什么结果。

lcpkg 依赖 vcpkg，如果你没安装 vcpkg，可以跑 lcpkg setup。

[JYC099]

请问在LCUI-develop目录下运行lcpkg install出现
'lcpkg' 不是内部或外部命令，也不是可运行的程序如何解决？

@JYC099

• 你安装 Node.js 运行环境了吗？
• 你跑 npm isntall -g lcpkg 命令安装了吗？
• 安装后 npm 在命令行窗口里输出了什么？有没有输出 lcpkg 安装路径？
