从源代码安装 Python 3.6.3 后没有名为“lsb_release”的模块

平台：ubuntu 17.04服务器

ubuntu 17.04 服务器安装包含 python 2.7 和 python 3.5。我从源代码手动安装了 Python 3.6.3。但是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'

但如果我修改文件的第一lsb_release行

#!/usr/bin/python3 -Es

到

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

它又能工作了。

# lsb_release -a

以下是模块搜索路径：

有谁知道如何修理它？

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：

我们可以看到/usr/bin/lsb_release

#!/usr/bin/python3 -Es

import lsb_release

关键步骤是import lsb_release，但是问题是Python 3.6没有这个模块。

所以，您必须覆盖python3从python3.5到python3.6。这就是您的lsb_release损坏的原因。

为了验证这一点，我们可以看到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'

然后在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'

这个文件在哪里：

➜  ~ 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

所以，这个模块lsb_release在 中存在python3.5，但在 中不存在python3.6。我们最终找到了它！

现在让我们通过添加原始文件的链接来修复它lsb_release.py！

这个对我有用！

lsb_release我建议通过 apt重新安装：

  1. 打开终端窗口
  2. 跑步sudo apt install --reinstall --mark-auto lsb-release
