tar文件compressionerror BZ2模块不可用

Question

我试图安装扭曲 PIP安装https://pypi.python.org/packages/18/85/eb7af503356e933061bf1220033c3a85bad0dbc5035dfd9a97f1e900dfcb/Twisted-16.2.0.tar.bz2#md5=8b35a88d5f1a4bfd762a008968fddabf

这是一个django-channels项目，我有以下错误的问题

Exception: 
Traceback (most recent call last): 
    File "/home/petarp/.virtualenvs/ErasmusCloneFromGitHub/lib/python3.5/tarfile.py", line 1655, in bz2open

    File "/usr/local/lib/python3.5/bz2.py", line 22, in <module> 
    from _bz2 import BZ2Compressor, BZ2Decompressor 
ImportError: No module named '_bz2' 

During handling of the above exception, another exception occurred:

显然我m缺少bz2模块，所以我试图手动安装它，但是没有解决python 3.5问题，所以我该如何解决这个问题？

我做了什么@ e4c5建议，但我这么做是为了python3.5.1，输出

我在Ubuntu 14.04 LTS和我已经安装了从源蟒蛇3.5。

Answer 1

在我的python 3.4安装中，我似乎没有任何问题import bz2。所以，我没有

import bz2 
print (bz2.__file__) 

并发现它位于/usr/lib/python3.4/bz2.py然后我做了

dpkg -S /usr/lib/python3.4/bz2.py 

这表明：

libpython3.4-STDLIB：AMD64：/ usr/lib中/ python3 .4/bz2.py

因此，下面的命令应该有希望解决这个问题：

apt-get install libpython3.4-stdlib 

更新：

如果您已经从源编译蟒蛇3.5，这是非常有可能的BZ2尚未在编译首先做

./configure --with-libs='bzip' 

同样请重新安装。也适用于python 3.6。请注意，这可能会抱怨其他缺失的依赖关系。您必须逐个安装缺失的依赖项，直到涵盖所有内容。
