lsb_release - 无法将字符串转换为浮点数：'8.04 LTS'

tag-icon • tag-icon pip lsb-release
lsb_release - 无法将字符串转换为浮点数：'8.04 LTS'

在我的计算机上，所有依赖该lsb_release命令的东西都无法运行。

例子：

pip install numpy

引发子进程.CalledProcessError（代码、cmd、stdout、stderr）子进程.CalledProcessError：命令‘lsb_release -a’返回非零退出状态 1

事实上，lsb_release -a会产生错误

File "/usr/bin/lsb_release", line 95, in <module>
    main()
  File "/usr/bin/lsb_release", line 59, in main
    distinfo = lsb_release.get_distro_information()
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 383, in get_distro_information
    distinfo = guess_debian_release()
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 281, in guess_debian_release
    get_distro_info(distinfo['ID'])
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 41, in get_distro_info
    RELEASES_ORDER.sort(key=lambda n: float(n[0]))
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 41, in <lambda>
    RELEASES_ORDER.sort(key=lambda n: float(n[0]))
ValueError: could not convert string to float: '8.04 LTS'

我知道在python中'8.04 LTS'不能转换为float，但是为什么会发生这种情况。

我尝试重新安装两者lsb_release，python-pip但问题依然没有得到解决。

我在线Ubuntu 16.04 LTS。有什么帮助吗？

答案1

我的一台虚拟机出现了同样的错误，其他两台虚拟机和虚拟机管理程序都正常。同一版本（16.04.3），不知道是什么原因造成的。这是一个已知错误。

我松了一口气这里

修改文件/usr/share/pyshared/lsb_release.py第 41 行：

RELEASES_ORDER.sort(key=lambda n: float(n[0]))

到：

RELEASES_ORDER.sort(key=lambda n: float(n[0].split()[0]))

帮我解决了问题。Ubuntu bug launchpad 上的 SHIINA Hideaki (shiina) 功不可没。我只是在这里重新发布它。

当我运行时出现问题lsb_release -a

Traceback (most recent call last):
  File "/usr/bin/lsb_release", line 95, in <module>
    main()
  File "/usr/bin/lsb_release", line 59, in main
    distinfo = lsb_release.get_distro_information()
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 398, in get_distro_information
    distinfo = guess_debian_release()
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 288, in guess_debian_release
    get_distro_info(distinfo['ID'])
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 48, in get_distro_info
    RELEASES_ORDER.sort(key=lambda n: float(n[0]))
  File "/usr/lib/python3/dist-packages/lsb_release.py", line 48, in <lambda>
    RELEASES_ORDER.sort(key=lambda n: float(n[0]))
ValueError: could not convert string to float: '6.06 LTS'

让我们检查一下文件/usr/lib/python3/dist-packages/lsb_release.py

try:
    csvfile = open('/usr/share/distro-info/%s.csv' % origin.lower())
except FileNotFoundException:
    # Unknown distro, fallback to Debian
    csvfile = open('/usr/share/distro-info/debian.csv')

....

RELEASES_ORDER = list(RELEASE_CODENAME_LOOKUP.items())
RELEASES_ORDER.sort(key=lambda n: float(n[0]))

它加载文件/usr/share/distro-info/%s.csv，并将第一项转换为浮点类型，该类型可能包含像“LTS”这样的字符串。因此，我修改了第 48 行，/usr/lib/python3/dist-packages/lsb_release.py如下所示，它对我有用。

RELEASES_ORDER.sort(key=lambda n: (n[0]))
