conda create -n name python=3.7无法创建问题合集

错误1：

CondaHTTPError: HTTP 000 CONNECTION FAILED for url

解决方法一，直接解决：

1、修改镜像源

参照：https://blog.csdn.net/Michael_Cretu_/article/details/122727872

# 显示镜像源
conda config --show-sources
# 添加镜像源(example)
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/linux-64/
# 删除镜像源(example)
conda config --remove channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/linux-64/

参照：https://www.cnblogs.com/tianlang25/p/12433025.html

再次修改：

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

此次报错为：

https://www.cnblogs.com/tianlang25/p/12433025.html 再次删除镜像源：conda config --remove-key channels，重新开始，错误又变回原来的错误

 

2、看错误描述像是是清华镜像的问题，于是查看conda信息

参照：新建虚拟环境时出错CondaHTTPError: HTTP 000 CONNECTION FAILED for url 问题：创建虚拟环境时，出现以下错误 解决1.看错误描述像是是清华镜像的问题，于是查看conda信息 2.于是我删除了所有的清华镜像。 3.再次查看conda信息（已删除） 4.在此新建虚拟环境，成功 参考： 删除镜像源+pyt…https://zhuanlan.zhihu.com/p/432658829

（1）查看conda信息

conda info

（2）删除所有清华镜像：

conda config --remove-key channels

（3）再次查看conda信息

conda info

（4）创建新虚拟环境

 仍不成功，报错信息为：

 3、删除.condrac文件

参考：Python&aconda系列：conda创建虚拟环境、切换环境 报错-CSDN博客

但是在XFTP中，找不到.condrac文件

解决办法：

1、设置 ------> 勾选”显示隐藏的文件“

2、删除.condrac文件

结果：conda create -n name python=3.7仍然报错

3、重新创建.condrac文件

参照：anaconda换清华源后报错解决（1） - 知乎

删除.condrac中的default；

将https改为http也不行；

解决方法二，换种方法解决：

1、conda 在断网情况下创建虚拟环境

参考地址：conda 在断网情况下创建虚拟环境_repodata.json.bz2-CSDN博客

conda create -n py37SSEGCN --clone base

下载base中的包失败

2、clone其他虚拟环境 

参考：Conda创建环境失败：CondaHTTPError: HTTP 000 CONNECTION FAILED-CSDN博客

（1）添加镜像源 

conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
conda config --set show_channel_urls yes

（2）clone其他镜像源

conda create -n py37SSEGCN --clone py37dgcn

成功！！！
