python2.7使用PIP

python安裝守護程序包當我嘗試安裝Python daemon package我得到這個錯誤所有的時間（安裝使用PIP命令&下載文檔，並用PIP安裝試過）：python2.7使用PIP

我是新來的python，搜索錯誤代碼，並使用其他線程提供的步驟沒有解決問題。

只要寫pip install python-daemon==2.1.2

無需下載python-daemon-2.1.2.tar.gz文件在使用PIP一封來自PyPI安裝。

如果要使用下載的軟件包請按照下列步驟

焦油xvf命令蟒蛇守護-2.1.2.tar.gz
CD蟒蛇守護-2.1.2
蟒蛇setup安裝.py install

您拯救了我的星期日朋友，非常感謝和來自德國的一切！你如何知道選擇哪個版本？ – wichtel

對於最新版本，您可以使用'pip install python-daemon'。 –

但你怎麼知道使用哪個版本，所以它會工作？ – wichtel
