如何将 compile_commands.json 与 llvm clang (版本 7.0.1） python 绑定一

我正在尝试打印出给定C++文件中的所有AST节点。我提供了一个有效的C++文件，该文件在其父目录中有一个 compile_commands.json 文件。所有步骤就像如何将 compile_commands.json 与 clang python 绑定一起使用一样？我的 clang 版本是："clang 版本 7.0.1(标签/RELEASE_701/最终( 目标：x86_64-pc-windows-msvc 螺纹型号：磅 已安装目录： C：\Program Files\LLVM\bin".操作系统是windows10，python版本是2.7。但是，当我在下面运行此脚本时。

在此处输入代码

import clang.cindex
from clang.cindex import *
libclang_path = r'C:Program FilesLLVMbinlibclang.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()

有一些错误，如下所示。我认为此错误的原因是"file_args = compdb。GetCompileCommands (source_file_path("此行返回的是 CompileCommand 实例，而不是字符串或整数类型，因此 index.parse(( 不能直接接受此实例作为参数。但这似乎在旧版本的libclang中返回了一些字符串类型的"命令"。这让我现在感到困惑。
