Exception: 
Traceback (most recent call last): 
    File "/usr/local/lib/python3.4/tarfile.py", line 1642, in bz2open

    File "/usr/local/lib/python3.4/bz2.py", line 20, in <module> 
    from _bz2 import BZ2Compressor, BZ2Decompressor 
ImportError: No module named '_bz2' 

During handling of the above exception, another exception occurred:

    raise CompressionError("bz2 module is not available") 
tarfile.CompressionError: bz2 module is not available

爲什麼人們不讀錯誤信息？它清楚地說明了爲什麼失敗：'ImportError：沒有名爲'_bz2'的模塊 – Dawid

看起來好像您沒有在您的雲服務器上安裝bzip模塊。這很可能與缺少bzip2庫缺失有關。

爲了安裝它，您可以鍵入：

apt-get install bzip2

您可能需要前綴sudo該命令。

誠實地說，它應該是「開箱即用」的，因爲這是Python的主要優勢之一。希望這有助於！
