问题描述

我正在尝试安装一个工具包，我正在使用 ubuntu 在 WSL 上 - 我昨天下载了 ubuntu.以下是此工具包的安装过程.在windows cmd上它说我有python 3.7.9但在ubuntu上它说我有python 3.8.2

I am trying to install a toolkit, I'm on WSL using ubuntu - I downloaded ubuntu yesterday. Here is what the installation process looks like for this toolkit. On windows cmd it says I have python 3.7.9 but on ubuntu its saying I have python 3.8.2

git clone https://github.com...
cd program
pip install -e .

或:

pip install program

pip install -e . 对我不起作用，我收到此错误:

pip install -e . is not working for me, I get this error:

user@DESKTOP-REA10BN:~/gym$ pip install -e .

Command 'pip' not found, but there are 18 similar ones.

但是，我检查并安装了 pip，这是我在运行前检查的内容:

however, I checked and I have pip installed, here's what I checked for before running:

user@DESKTOP-REA10BN:~$ cd\
> sudo apt-get install python-pip
cdsudo: command not found
user@DESKTOP-REA10BN:~$ python3 --version
Python 3.8.2
user@DESKTOP-REA10BN:~$ python3-pip --version
python3-pip: command not found
user@DESKTOP-REA10BN:~$ which pip3
/usr/bin/pip3
user@DESKTOP-REA10BN:~$ pip3 -V
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

推荐答案

简短回答:尝试运行 python3 -m pip install -e .

一些解释:

Python 的不同版本并不奇怪.WSL 实际上是一个超轻量级的虚拟机.您的 Windows python 安装完全独立于 WSL python 安装.

The different versions of Python are not surprising. WSL is, effectively, an ultra-lightweight virtual machine. Your Windows python installation is entirely independent of the WSL python installation.

Python 有两个广泛使用的主要版本，Python 2 和 Python 3.命令 python 运行 Python 2 的一些次要版本，而命令 python3 运行一些次要版本Python 3. 下面是我的控制台输出.

Python has two widely used major versions, Python 2 and Python 3. The command python runs some minor version of Python 2, while the command python3 runs some minor version of Python 3. Below is my console output.

lawruble@Balrog:~/scratch$ python --version
Python 2.7.18
lawruble@Balrog:~/scratch$ python3 --version
Python 3.8.5

Pip 是 Python 安装管理器，与 Python 的主要版本相同.命令 pip 运行 Python 2 版本的 pip，而 pip3 运行 Python 3 版本的 pip.

Pip is the python installation manager, and has the same major versions as Python. The command pip runs the Python 2 version of pip, while pip3 runs the Python 3 version of pip.

最好使用 python3 -m pip 而不是 pip3，这有助于确保您使用的 pip 版本与您期望使用的 Python 版本相关联运行.

It's better practice to use python3 -m pip over pip3, it helps ensure that you're using the version of pip associated with the version of python you expect to run.
