如何修正双重性B2 (Backblaze)错误

Question

当运行重复备份到B2 (Backblaze)时，它会失败，出现以下错误：

Attempt 1 failed. AttributeError: B2ProgressListener instance has no attribute '__exit__'
Attempt 2 failed. AttributeError: B2ProgressListener instance has no attribute '__exit__'
Attempt 3 failed. AttributeError: B2ProgressListener instance has no attribute '__exit__'
Attempt 4 failed. AttributeError: B2ProgressListener instance has no attribute '__exit__'
Giving up after 5 attempts. AttributeError: B2ProgressListener instance has no attribute '__exit__'

我使用以下命令行运行它：

  duplicity ~ b2://account:key@bucket

在B2桶中创建了一个空文件，所以对云的访问似乎是可行的。我的装置怎么了？

Ubuntu是16.04版。Python是2.7.12版本。口是心非是0.7.17版。b2后端为1.3.4。
