无法解决 OSError: [WinError 193] %1 不是有效的 Win32 应用程序

Question

我尝试在命令行上运行 python 代码。我遇到错误OSError: [WinError 193] %1 is not a valid Win32 application。

我是 python clang 包装函数的新手。 我正在使用 32 位的 python 3.7.2。 我正在使用 64 位版本 7.1.0 的 llvm。

    #!/usr/bin/env python   
    import sys
    import clang.cindex
    import ctypes
    clang.cindex.Config.set_library_path('C:/Program Files/LLVM/bin')



    print("argument1   ------> ",sys.argv[1])
    print("argument2   ------> ",sys.argv[2])


    def find_typerefs(node, typename):

        if node.kind.is_reference():
            ref_node = node.get_definition()
            if ref_node.spelling == typename:
                print( 'Found %s [line=%s, col=%s]' % (
                    typename, node.location.line, node.location.column))
        # Recurse for children of this node
        for c in node.get_children():
            find_typerefs(c, typename)




    index = clang.cindex.Index.create()




    tu = index.parse(sys.argv[1])
    print( 'Translation unit:', tu.spelling)
    find_typerefs(tu.cursor, sys.argv[2])

我尝试使用 subprocess.call([sys.executable, 'parser.py', 'dummyC++.cpp','person'],shell=True) 并得到同样的错误

  File "C:\Python37-32\lib\site-packages\clang\cindex.py", line 4129, in get_cindex_library
    library = cdll.LoadLibrary(self.get_filename())
  File "C:\Python37-32\lib\ctypes\__init__.py", line 434, in LoadLibrary
    return self._dlltype(name)
  File "C:\Python37-32\lib\ctypes\__init__.py", line 356, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 193] %1 is not a valid Win32 application

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "parser.py", line 30, in <module>
    index = clang.cindex.Index.create()
  File "C:\Python37-32\lib\site-packages\clang\cindex.py", line 2666, in create
    return Index(conf.lib.clang_createIndex(excludeDecls, 0))
  File "C:\Python37-32\lib\site-packages\clang\cindex.py", line 198, in __get__
    value = self.wrapped(instance)
  File "C:\Python37-32\lib\site-packages\clang\cindex.py", line 4103, in lib
    lib = self.get_cindex_library()
  File "C:\Python37-32\lib\site-packages\clang\cindex.py", line 4134, in get_cindex_library
    raise LibclangError(msg)
clang.cindex.LibclangError: [WinError 193] %1 is not a valid Win32 application. To provide a path to libclang use Config.set_library_path() or Config.set_library_file().

这是错误信息

从此安装 llvm 的 32 位版本(http://releases.llvm.org/download.html) 确保安装了 32 位版本的 python。 一切正常。
