Tidak ada modul bernama 'lsb_release' setelah menginstal Python 3.6.3 dari sumber

10

platform: server ubuntu 17.04

Instalasi server ubuntu 17.04 termasuk python 2.7 dan python 3.5. Saya menginstal Python 3.6.3 secara manual dari sumber. Namun, lsb_release -agagal:

# 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'

Tetapi jika saya memodifikasi baris pertama file lsb_releasedari 

#!/usr/bin/python3 -Es

untuk

#!/usr/bin/python3.5 -Es

itu bekerja lagi.

# lsb_release -a
LSB Version:    core-9.20160110ubuntu5-amd64:core-9.20160110ubuntu5-noarch:security-9.20160110ubuntu5-amd64:security-9.20160110ubuntu5-noarch
Distributor ID: Ubuntu
Description:    Ubuntu 17.04
Release:    17.04
Codename:   zesty

Berikut ini adalah jalur pencarian modul:

>>> import lsb_release
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'lsb_release'
>>> exit()

Adakah yang tahu cara memperbaikinya?

Saya pikir Anda mungkin harus hanya rm / usr / local / bin / python3, dan gunakan python3.6 secara eksplisit jika Anda ingin menggunakan 3.6 untuk sesuatu.

Mengapa Anda menginstal Python 3.6 dari sumber?
edwinksl
Sepertinya Anda mengatur instalasi Python yang berbeda sebagai default di sistem Ubuntu Anda. Ini diketahui menyebabkan banyak masalah karena jalur pemasangan modul yang berbeda. Apa hasil dari readlink -f /usr/bin/python3dan /usr/bin/python3 --version?

Larutan:

sudo ln -s /usr/share/pyshared/lsb_release.py /usr/local/lib/python3.6/site-packages/lsb_release.py

Menjelaskan:

Kita bisa melihat /usr/bin/lsb_release

#!/usr/bin/python3 -Es

import lsb_release

Langkah kuncinya adalah import lsb_release, tetapi masalahnya adalah Python 3.6tidak memiliki modul ini.

Jadi, Anda harus mengganti python3dari python3.5ke python3.6. Itu sebabnya kamu lsb_releaserusak.

Untuk memverifikasinya, kita dapat melihat di 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'

lalu di 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'

di mana file ini:

➜  ~ 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

Jadi, modul ini lsb_releaseada python3.5tetapi tidak ada di python3.6. Dan akhirnya kami menemukannya!

Sekarang mari kita perbaiki dengan menambahkan tautan ke lsb_release.pyfile asli !

Ini bekerja untuk saya!
