「SSLError：讀操作超時」使用PIP

Question

時每當我試着用pip我碰到下面的錯誤安裝的東西：

Downloading/unpacking Django>=1.5.1,<1.6 (from -r requirements.txt (line 1)) 
  Downloading Django-1.5.4.tar.gz (8.1MB): 8.0MB downloaded

這過去時常發生在我的時間，但現在我無法安裝任何東西。我嘗試添加--timeout=600，但在相同的時間內（達到8.0M後幾秒）失敗。
關於如何解決這個問題的任何想法？

Answer 1

嘗試（注意--default）：

pip --default-timeout=100 install django 

，如果它仍然無法正常工作，您可以手動下載django1.5.4和：

https://docs.djangoproject.com/en/dev/topics/install/#installing-an-official-release-manually

類似的問題：

pip search django produces time out error, pip install django timeout on MacOSX Lion

Answer 2

使用sudo pip install解決了我的問題（在我的本地計算機上）。我知道這個問題很古老，但對於將來遇到這種麻煩的任何人來說，這是我的工作。 :)

Answer 3

這通常是因爲互聯網連接弱，即;在安裝過程中丟失互聯網連接重做命令，它應該工作正常。
