大佬，我开始按照你给的思路重新弄了下  开始可以运行出一部分，有输出但是报错，再次运行又不行了

这是什么原因呢

subprocess.run([CMAKE_CMD, '-GNinja', '-B', builddir, f'-DTARGET_OS={os_name}', f'-DTARGET_ARCH={arch}',显然你要关注这一句，可能是没装cmake或者啥的，下次遇到问题你就单独把运行的指令拆出来自己跑一遍就知道为啥了

仔细看说明： Install git and python 3 

Install latest Visual Studio with "Desktop development with C++" and "C++ CMake tools" 

Install required libraries (libcapstone and libicu4c) 

python scripts\init_env_win.py

• Start "x64 Native Tools Command Prompt"

换成中文就是
1.安装Python √

2.安装 Visual Studio 安装 c++桌面开发库 和 c++ cmake 工具 √

3.安装需要的库 libcapstone 和 libicu4c ?

4.在blutter目录下 运行 

python scripts\init_env_win.py

运行 x64 Native Tools Command Prompt for VS 2022 命令行工具 

最后执行你的命令，祝你好运!

如果不知道在哪里找到去开始按钮里面找到 vs -> vc 看看图1

我的执行没有报错 图2~!

Dart最低支持是2.16，你的版本过低
