Question

我想使用copy_tree函数将一个目录的内容复制到另一个目录中。以下是我的代码：

copy_tree('/opt/Deployment/scripts/image', '/opt/Deployment/dist-packages/job-123')

目录image中的几个文件被复制到job-123，但在此之后，我收到此错误：

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/rpyc/core/protocol.py", line 305, in _dispatch_request
    res = self._HANDLERS[handler](self, *args)
  File "/usr/local/lib/python2.7/dist-packages/rpyc/core/protocol.py", line 535, in _handle_call
    return self._local_objects[oid](*args, **dict(kwargs))

    execute(text, self.exposed_namespace)

  File "/usr/lib/python2.7/distutils/dir_util.py", line 163, in copy_tree
    verbose=verbose, dry_run=dry_run))
  File "/usr/lib/python2.7/distutils/dir_util.py", line 167, in copy_tree
    dry_run=dry_run)
  File "/usr/lib/python2.7/distutils/file_util.py", line 148, in copy_file
    _copy_file_contents(src, dst)
  File "/usr/lib/python2.7/distutils/file_util.py", line 44, in _copy_file_contents
    fdst = open(dst, wb)
IOError: [Errno 2] No such file or directory: /opt/Deployment/dist-packages/job-123/lib/utils.pyc

现在，此文件utils.pyc位于lib子目录的源目录中，它应该被复制到目标中的同一子目录中。为什么copy_tree期望它已存在并抛出错误？

distutils.dir_util.copy_tree在复制之前需要目标文件
