No module named 'lsb_release' after install Python 3.6.3 from source
platform: ubuntu 17.04 server
The ubuntu 17.04 server installation includes python 2.7 and python 3.5.
I installed the Python 3.6.3 manually from source. However, lsb_release -a failed:
# 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'
But if I modify the first line of the file lsb_release from
#!/usr/bin/python3 -Es
to
#!/usr/bin/python3.5 -Es
it works again.
# lsb_release -a

Does anyone know how to fix it?
Solution 1:
Solution:
sudo ln -s /usr/share/pyshared/lsb_release.py /usr/local/lib/python3.6/site-packages/lsb_release.py
Explain:
We can see in /usr/bin/lsb_release
#!/usr/bin/python3 -Es
# lsb_release command for Debian

The key step is import lsb_release, but the problem is Python 3.6 doesn't have this module.
So, you must have overrided python3 from python3.5 to python3.6. That's why your lsb_release is broken.
To verify it, we can see in python3.6:
➜ ~ 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'
then in python3.5:
➜ ~ 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'
where is this file:
➜ ~ 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
So, this module lsb_release exist in python3.5 but not exist in python3.6. And We find it eventually!
Now let's fix it through add a link to the original lsb_release.py file!
It works for me!
