平台：ubuntu 17.04服务器
ubuntu 17.04服务器安装包括python 2.7和python 3.5。
我从源手动安装了Python 3.6.3。但是，lsb_release -a失败了：
root@birds:~# lsb_release -a
Traceback (most recent call last):
File "/usr/bin/lsb_release", line 25, in <module>
import lsb_release
ModuleNotFoundError: No module named 'lsb_release'
但是，如果我修改文件lsb_release的第一行
#!/usr/bin/python3 -Es
至
#!/usr/bin/python3.5 -Es
它又有效了。
root@birds:~# lsb_release -a

有谁知道如何修复它？感谢。

<强>解决方案：
sudo ln -s /usr/share/pyshared/lsb_release.py /usr/local/lib/python3.6/site-packages/lsb_release.py
<强>说明：
我们可以在/usr/bin/lsb_release
#!/usr/bin/python3 -Es
# lsb_release command for Debian

import lsb_release
关键步骤是import lsb_release，但问题是Python 3.6没有此模块。
所以，您必须覆盖从python3到python3.5的{{1}}。这就是你python3.6被打破的原因。
要验证它，我们可以在lsb_release中看到：
python3.6然后在➜ ~ python3.6
Python 3.6.4 (default, Feb 6 2018, 16:57:12)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import lsb_release
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'lsb_release'
：
python3.5此文件在哪里：
➜ ~ python3.5
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import lsb_release
>>> lsb_release.__file__
'/usr/lib/python3/dist-packages/lsb_release.py'
因此，此模块➜ ~ ll /usr/lib/python3/dist-packages/lsb_release.py
lrwxrwxrwx 1 root root 38 Jul 7 2016 /usr/lib/python3/dist-packages/lsb_release.py -> ../../../share/pyshared/lsb_release.py
存在于lsb_release中，但不存在于python3.5中。我们终于找到了它！
现在让我们通过添加原始python3.6文件的链接来修复它！
对我有用！

这种情况是在dist-packages消失或无法被python安装访问时发生的。
当我在dist-packages/中删除/usr/lib/python3时遇到了这个问题-因为有些用户安装的软件包与我的本地软件包冲突。
要解决此问题，您可以尝试：
sudo apt reinstall lsb-release
这为我解决了。这也避免了清除lsb-release的兄弟姐妹问题。不用。
答案 2 :(得分：0)
我在 Raspberry Pi 上使用 python 3.6 和 python 3.7 遇到了同样的问题，但我认为它可以在任何地方工作。
唯一有效的方法是将 lsb_release 移动到备份文件中。
sudo mv /usr/bin/lsb_release /usr/bin/lsb_release_back
可以在此处找到完整的文档：[readthedocs.io].[1]https://neoctobers.readthedocs.io/en/latest/rpi/install_python3.html
答案 3 :(得分：-1)
您只需清除现有的lsb发行版，然后重新安装。它将解决您的问题。
$ sudo apt purge lsb-release
$ sudo apt install lsb-release
