HTTP 000 连接失败

Question

使用 miniconda 全新安装 python 3.7.11 后，尝试安装 pandas 但失败：

(base) C:\Users\jisib>conda install pandas
Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

If your current network has https://www.anaconda.com blocked, please file
a support request with your network engineering team.

'https://repo.anaconda.com/pkgs/main/win-64'

我对 python 很陌生，所以可能是一个非常基本的错误:)。 anaconda.com 未被阻止 （https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json也不是）

先尝试创建环境但失败了：

(base) C:\Users\jisib>conda create --name myenv2022_03
Collecting package metadata (current_repodata.json): done
Solving environment: done

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json>

谢谢您的帮助！

Answer 1

只需复制这些：-

libcrypto-1_1-x64.dll

libssl-1_1-x64.dll

来自 C:\Anaconda3\Library 到 C:\Anaconda3\DLLs。

Answer 2

错误来自新的 SSL 策略。

忽略 SSL 验证并尝试安装 pandas

conda config --set ssl_verify false

或者 蟒蛇提示

set SSL_NO_VERIFY=1

Answer 3

对我来说，删除 Windows 上的环境变量“SSLKEYLOGFILE”是有效的。

Answer 4

您是否尝试过使用 pip 安装程序，或使用 Anaconda Prompt 进行安装？要使用 pip 安装，请在创建虚拟环境后，打开终端控制台并尝试：

source activate [name of virtual environment]
pip install pandas
