标签: python-3.7 dpkg

我试图使用'sudo apt-get install python3.7'在Ubuntu虚拟机中安装python 3.7。 但是,我得到以下输出:-

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).

然后,我尝试按照上述输出中的建议执行'apt-get -f install',但随后得到了以下内容:-

更新

即使错误表明python3.7已经存在,当我执行python时,我也会得到以下信息:

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.

以下在我运行“ python3”时:-

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.

我要做的就是安装python 3.7。

有人可以帮助我解决这个错误吗?

答案 0 :(得分:0)

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。

你能试试吗 命令行上的pythonpython3,看看它说了什么? 如果您看到类似以下的内容,则说明它已成功安装

  Python 3.7.3 (v3.7.3 Oct  3 2017, 00:32:08)
