解决方法一(用此方法解决)参考链接
一、输入以下代码,查看是否存在.condarc文件。
$ conda config --show-sources
出现以下代码,就代表根目录下自动生成了.condarc文件
==> /home/wangchunxiao/.condarc <==
二、如果生成了此文件,将此文件删除
rm -rf ~/.condarc
预备方法
1、关闭VPN!(在用上面的方法时,我已经提前将VPN关掉了,不知道原理但是可以试试。)参考链接
2、尝试输入以下命令行。(尝试过了,没有奏效也没出别的大事)参考链接
conda clean -i
#这句话的目的是删除缓存和索引。
3、尝试输入以下命令行。(没有尝试,看起来很吓人,不敢动!)参考链接
conda clean --packages && conda clean --all && conda update --all
#清除所有包,清除所有东西,更新所有东西
