Python: tbird2claws.py问题

Question

我正在尝试将我的归档消息+文件夹结构从雷鸟迁移到爪子。开发人员(和其他人)建议尝试使用Python tbird2claws.py (“将Mozilla邮箱集成到爪子邮件”)。

但是，我收到以下错误消息：

root@debian:~/.thunderbird/f6tkjcoh.default# python $HOME/Downloads/claws-mail-tbird2claws/tbird2claws.py . ~/Mail
Traceback (most recent call last):
  File "/root/Downloads/claws-mail-tbird2claws/tbird2claws.py", line 130, in <module>
    convert_tree(sys.argv[1], sys.argv[2])
  File "/root/Downloads/claws-mail-tbird2claws/tbird2claws.py", line 124, in convert_tree
    os.path.join(out_treepath,outpath,f))
  File "/root/Downloads/claws-mail-tbird2claws/tbird2claws.py", line 95, in process_file
    offs = harvest_offsets(filepath)
  File "/root/Downloads/claws-mail-tbird2claws/tbird2claws.py", line 63, in harvest_offsets
    for i,line in enumerate(open(filepath)):
IOError: [Errno 2] No such file or directory: './lock'

问题

1. 这些错误意味着什么？
2. 如何使这个脚本运行良好？
3. 还有其他的想法吗?如何将归档消息+文件夹结构从雷鸟迁移到爪子？

tbird2claws.py文件：

This module integrates your Mozilla Thunderbird 1.0 tree to
your Claws Mail MH mailbox tree.

The script receives two parameters from command-line:
 <Thunderbird folder path> <Claws Mail folder path>

Best way to use it is to go to inside yout Thunderbird
root mailfolder directory and invoke it as:

  <path>\python2.4 <path>\tbird2syl.py . <path to claws mail>\Mail

This idiom will avoid the creation of the folder Thunderbird inside
your Claws Mail folder tree.

If the names of your directories match in both trees, files should
be placed in the correct folder.

This is an alpha release, so it may be a little rough around the edges.
Nevertheless, I used it with great success to convert a very large and
deep folder tree.

Please, do backup your claws-mail (destination) folder tree before trying
this out. Live safe and die old!

根据https://github.com/avocado-framework/avocado/issues/818的说法，当您再次运行脚本时，这个问题将自行解决。
