从源代码安装Python3.6.3后没有名为“lsb_release”的模块
从源代码安装Python3.6.3后没有名为“lsb_release”的模块

平台:Ubuntu17.04服务器
Ubuntu17.04服务器安装包括python2.7和python3.5。我从源代码手动安装了Python3.6.3。然而，lsb_release -a失败了：
# 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它又起作用了。
# lsb_release -a

解决方案：
sudo ln -s /usr/share/pyshared/lsb_release.py /usr/local/lib/python3.6/site-packages/lsb_release.py解释：
我们可以在/usr/bin/lsb_release中看到
#!/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没有这个模块。
因此，您必须将python3从python3.5过度到python3.6**。这就是为什么你的** lsb_release坏了。
要验证它，我们可以在python3.6中看到：
➜ ~ 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'然后在python3.5中：
➜ ~ 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'这份文件在哪里：
➜ ~ 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因此，该模块lsb_release存在于python3.5中，而不存在于python3.6中。我们最终会找到的！
现在，让我们通过添加到原始lsb_release.py文件的链接来修复它！
这对我有用！
