std::filesystem::path 在標頭<filesystem>定義 classpath; (C++17 起) 類型path的對象表示文件系統上的路徑。只有路徑的語法外觀得到處理:路徑名可能表示不存在的路徑,或甚至不允許存在於當前文件系統或操作系統的路徑。 路徑名擁有下列語法: 根名(可選):標識具有多根的文件系統(如"C:"或"//myserver")的根。
std::filesystem::path C++ Filesystem library std::filesystem::path Defined in header<filesystem> classpath; (since C++17) Objects of typepathrepresent paths on a filesystem. Only syntactic aspects of paths are handled: the pathname may represent a non-existing path or even one that is not...

if it is8.3.0as shown, then there seems to be compiler bug as reported here:https://stackoverflow.com/questions/56738708/c-stdbad-alloc-on-stdfilesystempath-append could you try building the libs with9.0and see if the issue goes away?
定义于头文件 <filesystem> class path; (C++17 起) 类型path 的对象表示文件系统上的路径。只有路径的语法外观得到处理:路径名可能表示不存在的路径,或甚至不允许存在于当前文件系统或操作系统的路径。 路径名拥有下列语法: 根名(可选) :标识具有多根的文件系统(如 "C:" 或"//myserver" )的根。有歧义...
root-name(optional): identifies the root on a filesystem with multiple roots (such as"C:"or"//myserver"). POSIX filesystems have single root. root-directory(optional): a directory separator that, if present, marks this path asabsolute. If it is missing (and the first element other than...
