python-3.7 - 安装 Python 3.7 时出错 - E：子进程 /usr/bin/dpkg 返回错误代码 (1)

问题描述

我试图使用“sudo apt-get install python3.7”在我的 Ubuntu 虚拟机中安装 python 3.7。但是，我得到了以下输出： -

Building dependency tree       
Reading state information... Done
python3.7 is already the newest version (3.7.4-2~16.04.york1).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libpython3.7 : Depends: libpython3.7-stdlib (= 3.7.4-2~16.04.york1) but 3.7.4-1+xenial2 is to be installed
 libpython3.7-dev : Depends: libpython3.7-stdlib (= 3.7.4-2~16.04.york1) but 3.7.4-1+xenial2 is to be installed
 libpython3.7-stdlib : Depends: libpython3.7-minimal (= 3.7.4-1+xenial2) but 3.7.4-2~16.04.york1 is to be installed
 python3.7 : Depends: libpython3.7-stdlib (= 3.7.4-2~16.04.york1) but 3.7.4-1+xenial2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

之后，我尝试按照上述输出中的建议执行“apt-get -f install”，但随后得到以下结果：-

更新：

即使错误表明 python3.7 已经存在，但当我执行时python，我得到以下信息：

Python 2.7.12 (default, Oct  8 2019, 14:14:10) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.

当我运行'python3'时在下面： -

Python 3.5.2 (default, Oct  8 2019, 13:06:37) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

我想做的就是安装python 3.7。

谁能帮我解决这个错误？

解决方案

我在您的日志中看到以下内容

python3.7 is already the newest version (3.7.4-2~16.04.york1).

它说python3.7已经安装。

您可以尝试一下 python还是python3在命令行上，看看它说了什么？如果您看到类似下面的内容，则它已成功安装

  Python 3.7.3 (v3.7.3 Oct  3 2017, 00:32:08) 
 [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on XXX
