无法创建虚拟环境 [英] cannot create a virtual environment

问题描述

我最近将操作系统更改为Windows 10并设置了anaconda3.问题是在Anaconda Navigator(位于环境"选项卡中)中，在设置名称和名称后，单击创建"按钮以创建新的虚拟环境.python版本(到3.7作为唯一选项)，将不会创建venv，而是出现此错误:

I've recently changed my OS to windows 10 and setup anaconda 3. The problem is that in Anaconda Navigator (in the Environment tab) when clicking on the create button to make a new virtual environment, after setting a name and the python version (to 3.7 as the only option), the venv won't be created, instead, I get this error:

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win- 
64/current_repodata.json><br>Elapsed: -<br><br>An HTTP error occurred when trying to retrieve this 
URL.<br>HTTP errors are often intermittent, and a simple retry will get you on your way.<br><br>If 
your current network has https://www.anaconda.com blocked, please file<br>a support request with your 
network engineering team.<br><br>'https://repo.anaconda.com/pkgs/main/win-64'<br> 

尽管我可以在浏览器中打开此文件: https://repo.anaconda.com/pkgs/main/win- 64/current_repodata.json

Although I can open this file in my browser: https://repo.anaconda.com/pkgs/main/win- 64/current_repodata.json

另一方面，当我尝试按照以下步骤制作虚拟环境时:

On the other hand, when I try to make a virtual env following these steps:

mkdir projects
cd projects
mkdir drdr
cd drdr
python -m venv ./venv

然后当我如下激活venv时:

Then when I activate the venv like below:

venv\Scripts\activate.bat

我得到:

(venv) (base) C:\Users\shima\projects\drdr>

我不知道什么是(venv)(基础).我是否应该意识到它已激活.即使当我尝试通过以下代码激活我的venv时:

which I don't know what is (venv) (base). Should I realize it activated or not. Even when I try to activate my venv by the code below:

conda activate venv

我收到此消息:

Could not find conda environment: venv

此外，制作venv之后，无论我选择在venv文件夹中的哪个文件夹，都想将其导入到导航器中，都无法导入

Also, after making the venv, when I want to import it in my navigator no matter I choose which folder inside my venv folder, I can't import it

顺便说一句，检查防火墙是否允许来自anaconda的流量，我无法在允许的应用程序列表中找到anaconda，然后尝试将其添加到该列表中，我不知道应该在anaconda文件夹中添加哪个文件夹

By the way, checking whether firewall allows traffic from anaconda, I cannot find anaconda in the list of allowed apps and trying to add it the list, I don't know what folder inside anaconda's folder I should add

我不知道为什么会发生此问题，并且无法在anaconda文档中找到答案，也无法在StackOverflow中找到其他问题，因此，我真的很感激此问题.

I don't know why this problem has happened, and couldn't find an answer in anaconda documents or others questions here in StackOverflow, so I really appreciate any help in this issue.

非常感谢！

推荐答案

python -m venv ./venv

您正在将 conda 虚拟环境与 virtualenv 虚拟环境混合在一起，因此造成了所有混乱:

you are mixng conda virtual environments with virtualenv virtual environments, hence all the confusion:

(venv) (base) C:\Users\shima\projects\drdr>

看起来很奇怪，因为确实如此.您处于conda的 base 环境中，但是已激活一个称为 venv

does look strange, because it is. You are in the baseenvironment of conda, but have activated a virtualenv environment called venv

找不到conda环境:venv

Could not find conda environment: venv

没有conda环境 venv ，您从未创建过该环境.

there is no conda enviroment venv, you have never created one.

简而言之:

使用conda时，请勿使用virtualenv，而应使用

When using conda, don't use virtualenv, insted use

 conda create -n venv

创建虚拟环境并

conda activate venv

激活它
