使用pip安裝需求

Question

我對使用python和pip很陌生，目前我正嘗試第一次運行python程序。 我下載的git上的程序和自述文件告訴我，運行命令：

pip install -r requirements.txt 

，我做到了。我現在有一個我不明白的例外。你可以幫幫我嗎？

我試着做sudo的東西，但它沒有幫助。我使用的OS X.

下面是我從終端得到了答案：

Answer 1

好吧，我似乎找到了解決辦法這樣做：

sudo pip install -r requirements.txt --upgrade --ignore-installed six 

雖然，我不真的不知道它做了什麼。
