remove命令和show命令的使用（场景conda删除channel ）

conda删除channel

今天装包，用conda install，发现清华的源貌似已经用不了。报错如下：

    CondaRuntimeError: Runtime error: Connection error: HTTPSConnectionPool(host
='mirrors.tuna.tsinghua.edu.cn', port=443): Max retries exceeded with url: /anac
onda/pkgs/free/win-64/repodata.json (Caused by ConnectTimeoutError(object at 0x0000000018726EF0>,
'Connection to mirrors.tuna.tsinghua.edu.cn timed out. (connect timeout=3.05)'))
: https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/win-64/

在删除前再学习一个命令，查看通道

conda config –show

add_anaconda_token: True
add_pip_as_python_dependency: True
allow_softlinks: True
always_copy: False
always_yes: False
auto_update_conda: True

我们用删除的命令把这个镜像个删除了,注意要把引号给去掉。

conda config –remove channels ‘https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/’

再来看show，里面已经没有清华源了。

conda config –show
