该python程序命令执行的Python 2. Python 3中可以使用来执行python3命令。如何使用python命令执行 Python 3 ？

I have Ubuntu 14.4.03. The default golang version which came with it was 1.2.1. I would like to update golang to 1.4 or higher.

After searching I found the way to do this would be to first delete current go installation and then re-install the new version.

I found the following go installation files in the following directory:

/usr/share/go
/usr/share/go/src/cmd/go
/usr/share/go/src/pkg/go
/usr/lib/go
/ur/lib/go/pkg/linux_amd64/go
/ur/lib/go/pkg/linux_amd64_race/go
/usr/bin/go

Which directory contains what? Which ones should I delete? What should be the location of …

我已经在我的 ubuntu 18.04 中安装了 python 2.7 和 python 3.7 但是当我

键入 python 它显示

  Command 'python' not found, but can be installed with:

  sudo apt install python3       
  sudo apt install python        
  sudo apt install python-minimal

  You also have python3 installed, you can run 'python3' instead.

但我已经安装了python。

which python
/home/tanvir/.pyenv/shims/python

which python3
/home/tanvir/.pyenv/shims/python3

我想python指出/home/tanvir/.pyenv/shims/python3的是，一旦我运行python path/to/script它就会运行python3 path/to/script

virtualbox和 和有virtualbox-6.1什么区别？

如果您将virtualbox PPA添加到您的系统（通过 /etc/apt/sources.list），您会发现您现在可以安装多个版本的 virtualbox。

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -

在 中查看Synaptic Package Manager，您将看到至少三个不同的版本。

有什么区别，我应该安装哪一个？
