Python3.10源码venv已经改变

我去了个人仓库做一些Python Leetcode，在将Kubuntu升级到22.04之后，我意识到当前的Venv不起作用。

我觉得我需要重新创建VENV。安装了Python3.10-VENV，但我无法源自并激活它。

实际上，VENV/bin/Activate不再存在。

该文件夹仅包含

python python3 python3.10

我尝试过的三个文件，但没有骰子，

source venv/bin/python3.10

因此自然而然地源venv/bin/Activate无效。想法？

I went to do some python leetcode on a personal repo and after I upgraded my Kubuntu to 22.04 I realized the current venv wasn't working.

I had figured I would need to recreate the venv.
Installed python3.10-venv but I cant source and activate it.

In fact venv/bin/activate doesn't exist anymore.

The folder only contains three files

python python3 python3.10

I had tried but no dice

source venv/bin/python3.10

So naturally source venv/bin/activate doesn't work. Ideas?

我安装了 Ubuntu 22.0.4，遇到了和你一样的问题，我用这种方式解决了这个问题。

安装 venv：

sudo apt-get update
sudo apt-get install python3-virtualenv

创建 venv：

virtualenv --python=/usr/bin/python3.10 (VENV-NAME)
python3.10 - m venv (VENV-NAME)
源(VENV-NAME)/bin/activate

检查&更新 pip:

pip list
并更新 pip 例如（在我的电脑中）：
(/home/amin/Desktop/prog/Django/moein/coffeinrider.com/Project/A/(VENV-NAME)/bin/python3.10 -m pip install --upgrade pip)

当尝试使用venv为Python创建虚拟设备时，必须使用已安装的Python版本，但必须使用venv库的版本系统也必须使用。这是设置虚拟环境的两个先决条件。

警告：我急忙这样做是因为我需要它，但请警告：这可能会破坏您的系统python，结果依靠它的应用程序可能会破坏。

我遇到的问题，符合给定的症状在这里，似乎是在尝试使用Python 3.10.8创建VENV时，使用了venv用于Python 3.8.10的模块。

因此，给定Python 3.8和Python 3.10已经使用apt安装，首先，我卸载了这些软件包：

sudo apt purge python3-venv python3.8-venv
sudo apt autoremove

然后我链接python3指向Python 3.10：

cd /usr/bin
sudo rm python3
sudo ln python3.10 python3

然后我安装了安装的VENV for Python3.10：

sudo apt install python3.10-venv

现在意味着为Python 3.8创建虚拟环境不起作用（因为Python3.8 VENV刚刚删除了）。我不确定是否有一种使它们都起作用的方法，而且我还没有尝试再次安装python3.8-venv并尝试两者，因为我需要我的3.10环境现在很快工作;-)。但是，在遵循Ubuntu 20内通常的升级路线时，似乎可能引入了一些冲突。

但是，Python 3.10的VENV现在应该按预期工作：

$ python3 -m venv .venv
$ source .venv/bin/activate
(.venv) $ python -V
Python 3.10.8
(.venv) $ pip install --upgrade pip
...
(.venv) $ pip list
Package    Version
---------- -------
pip        22.3
setuptools 63.2.0

When trying to create a virtual env using venv for Python, a version of Python that is already installed system-wide must be used, but a version of the venv library from the system must also be used. These are two pre-requisites for setting up a virtual environment.

WARNING: I did this in a hurry because I needed it but please be warned: this may break your system Python with a result that applications that rely on it may break.

The problem I had, matching symptoms given here, seems to be that when trying to create a venv using Python 3.10.8, the venv module for Python 3.8.10 was being used.

So, given Python 3.8 and Python 3.10 are already installed using apt, first of all I uninstalled these packages:

sudo apt purge python3-venv python3.8-venv
sudo apt autoremove

Then I linked python3 to point to Python 3.10:

cd /usr/bin
sudo rm python3
sudo ln python3.10 python3

Then I installed the venv for Python3.10:

sudo apt install python3.10-venv

This now means creating a virtual environment for Python 3.8 doesn't work (because Python3.8 venv has just been removed). I'm not sure if there is a means to have them both working, and I haven't yet tried to just install python3.8-venv again and try them both, as I need my 3.10 environment working quickly, right now ;-). But it seems possible there has been some conflict introduced when following the usual upgrade route within Ubuntu 20.

However, venv for Python 3.10 should now work as expected:

$ python3 -m venv .venv
$ source .venv/bin/activate
(.venv) $ python -V
Python 3.10.8
(.venv) $ pip install --upgrade pip
...
(.venv) $ pip list
Package    Version
---------- -------
pip        22.3
setuptools 63.2.0
