我正在尝试将此示例代码从 rust 编译为 wasm。它是一个生锈的板条箱，可让您创建/编写 excel 文件。我已经成功地使用cargo run运行它。
不幸的是，当我尝试将其编译为 Web 程序集时，我遇到了一个错误，指出在编译 bzip2-sys(一个生锈的箱子(时找不到库<stdlib.h>，一个常见的 C 库。
当我第一次尝试编译它时，它提示我安装 clang 我从这里开始(Windows 的预构建二进制文件(64 位和 32 位((，并且我已经C:Program FilesLLVMbin包含在系统 Path 环境变量中。我还安装了MinGW-w64，以及带有Visual C++构建工具的Visual Studio 2017。
您可以在下面看到Visual Studio Code中生成的整个错误。

假设文件是某个目录，您可能需要帮助 clang 找到它：

控制如何将 #includes 解析为文件的标志。
