用conda安裝任何東西都報錯. 開始懷疑是公司的鬼網絡問題.
將.condarc重命名, 重新嘗試, 一切又很正常, 以為是清華源TUNA的問題, 還想去https://github.com/tuna/ 報錯.
后來一次將https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r channel一行在.condarc中刪掉后, 一切又正常了. 莫名其妙啊..
最開始時懷疑是 raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)的問題, 以為是清華源那邊缺失channeldata.json導致找不到subdir, 但關鍵的文件是repodata.json還是存在且一樣的. 可能不是TUNA的問題.
于是重新仔細追查錯誤, 發(fā)現(xiàn)這個錯誤有三處:
raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)raise Response304ContentUnchanged()json.decoder.JSONDecodeError: Unterminated string starting at: line 184947 column 5 (char 5586731)
第一個網絡是可以下載對應repodata.json的, 第二個304重定向應該不是, 第三個是json解碼的問題. 搜了一下, 找到以下帖子:
噢, 原來還是公司網絡的鍋. 肯定是之前update repo信息時網絡有問題, 于是就出現(xiàn)了污染.
解決辦法
conda clean -i
然后重新隨便install 個東西, 會重新下載repo信息. 問題解決. NND的公司網絡...
附錯誤內容:
$ conda install numpy
