Conda更新在Centos上太多時間

Question

Conda在CentOS上花費太多時間。我運行命令conda --debug update conda。這裏是日誌不知道爲什麼它需要太多的時間。

Answer 1

這個問題是否爲您解決？調試輸出顯示的問題是，您無法訪問https://repo.continuum.io/pkgs/free/linux-64/repodata.json.bz2 - 這只是一個300KB的文件。但問題不是下載時間，而是您的客戶無法從該URL獲得響應。我在Continuum工作，我不知道任何服務中斷，這意味着repo.continuum.io在過去的24小時內沒有任何時間可用，但是我不是操作團隊的一部分。我會將該URL放入您的網絡瀏覽器或手機中，看看它是否可以爲您解決。如果確實如此，那麼在執行conda update命令的CentOS服務器上可能會出現問題。您始終可以嘗試使用wget或curl命令查看這些URL是否成功解析了URL。讓我們知道這些建議是否有助於您的工作，或者至少可以更好地找出問題的根源。

Answer 2

由此看來，問題不是下載花費太多時間，而是您無法從URL獲得響應。最可能的原因是因爲您的防火牆配置不正確，正如Ian建議的，看看您是否可以通過其他措施解決URL，甚至可能通過不同的計算機/ VM。
