如何使用compile_命令.json使用LLVMClang(7.0.1版)python绑定?

我试图打印出一个给定C++文件中的所有AST节点。我提供了一个有效的C++文件,它有一个编译程序命令.json父目录中的文件。所有步骤都和How to use compile_commands.json with clang python bindings?一样,我的clang版本是:“clangversion7.0.1(tags/RELEASE\u701/final) 目标:x86\u 64-pc-windows-msvc 螺纹型号:posix InstalledDir:C:\Program Files\LLVM\bin”。操作系统为windows10,python版本为2.7。但是,当我运行下面的脚本时。你知道吗

在此处输入代码

import clang.cindex
from clang.cindex import *

libclang_path = r'C:\Program Files\LLVM\bin\libclang.dll'

if Config.loaded == True:
    pass
else:
    Config.set_library_file(libclang_path)


def node_info(node):
    return {'kind': node.kind,
            'usr': node.get_usr(),
            'spelling': node.spelling,
            'location': node.location,
            'file': node.location.file.name,
            'extent.start': node.extent.start,
            'extent.end': node.extent.end,
            'is_definition': node.is_definition()
            }


def get_nodes_in_file(node, filename, ls=None):
    ls = ls if ls is not None else []
    for n in node.get_children():
        if n.location.file is not None and n.location.file.name == filename:
            ls.append(n)
            get_nodes_in_file(n, filename, ls)
    return ls


def main():
    compilation_database_path = 'C:/Users/liqiu/Desktop/md/gn/build/win/x64'

    source_file_path = 'C:/Users/liqiu/Desktop/md/.../video_camera_source.cpp'

    index = clang.cindex.Index.create()
    compdb = clang.cindex.CompilationDatabase.fromDirectory(compilation_database_path)

    try:
        file_args = compdb.getCompileCommands(source_file_path)
        translation_unit = index.parse(source_file_path, file_args)
        file_nodes = get_nodes_in_file(translation_unit.cursor, source_file_path)
        print [p.spelling for p in file_nodes]
    except clang.cindex.CompilationDatabaseError:
        print 'Could not load compilation flags for', source_file_path


if __name__ == '__main__':
    main()

有如下错误。我认为这个错误的原因是“file\u args=compdb。GetCompileCommands(source\u file\u path)“此行返回一个CompileCommand实例,而不是字符串或整数类型,因此索引.parse()无法直接接受此实例作为参数。但在旧版本的libclang中,这似乎返回了一些字符串类型的“命令”。这让我现在很困惑。你知道吗
