用conda安装任何东西都报错. 开始怀疑是公司的鬼网络问题.
将.condarc重命名, 重新尝试, 一切又很正常, 以为是清华源TUNA的问题, 还想去https://github.com/tuna/ 报错.
后来一次将https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r channel一行在.condarc中删掉后, 一切又正常了. 莫名其妙啊..
最开始时怀疑是 raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)的问题, 以为是清华源那边缺失channeldata.json导致找不到subdir, 但关键的文件是repodata.json还是存在且一样的. 可能不是TUNA的问题.
于是重新仔细追查错误, 发现这个错误有三处:
raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)raise Response304ContentUnchanged()json.decoder.JSONDecodeError: Unterminated string starting at: line 184947 column 5 (char 5586731)
第一个网络是可以下载对应repodata.json的, 第二个304重定向应该不是, 第三个是json解码的问题. 搜了一下, 找到以下帖子:
噢, 原来还是公司网络的锅. 肯定是之前update repo信息时网络有问题, 于是就出现了污染.
解决办法
conda clean -i
然后重新随便install 个东西, 会重新下载repo信息. 问题解决. NND的公司网络...
附错误内容:
$ conda install numpy
