On March 7, 2020, prepare the scratch, create a new environment with anaconda, execute “CONDA create – n scrapyenv python = 3.6”, and the result is “condahtterror: http 000 connection failed for URL & lt; https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/win-64/current_ repodata.json>”。 Here are my solution steps.

1、 Computer environment

Operating system: Windows 10 64 bit

Anaconda version: CONDA   4.8.2

2、 Solution steps

1. Open the power shell and execute the “CONDA config — remove key channels” command to restore Anaconda’s source to the default.

Because I thought there was a problem with the image of Tsinghua University, I wanted to restore the image to the default, and then re execute “CONDA create – n scrapenv python = 3.6”. It was found that the problem still occurred, but the prompt changed to “condahttpererror: http 000 connection failed for URL & lt; https://repo.anaconda.com/pkgs/main/win-64/current_ repodata.json>” Yes. After careful comparison of the previous errors, it is found that the descriptions are the same except that the mirror address is different. Therefore, I don’t think it appears on the mirror address.

2. Restore the anaconda image to the original image. Execute the following command on the power shell:

conda config --add channels - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free
conda config --add channels - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main

If the command is not executed successfully, execute “CONDA config — remove key channels” in Article 1.

3. After restoring the image to Tsinghua, I executed the command to create the environment again, but it was still unsuccessful. So try to open the address of the image“ https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main ”After opening, you will see the following interface:

  It seems to have found the problem: the image address should be added with “win-64”.

4. Enter “C: \ users \ administrator” and open “. Condarc”. You will see the following code:

ssl_verify: true
show_channel_urls: true

channels:
  - httpn://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main

Change the above code to

ssl_verify: true
show_channel_urls: true

channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/win-64

You may also see “- default” in channels: below. Please delete it

5. After modification, execute “CONDA create – n scrapyenv python = 3.6” again. The sound of the waves is still there!

6. Continuing to browse the website, some netizens said, “it must be HTTP, not HTTPS!”, So I tried to modify it,

ssl_verify: true
show_channel_urls: true

channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/win-64

Execute “CONDA create – n scrapyenv python = 3.6” again, successfully!!!

7. According to in https://mirror.tuna.tsinghua.edu.cn/help/anaconda/ The final “. Condarc” is

ssl_verify: true
show_channel_urls: true

channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/win-64/
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/win-64/
