使用pip python2.7安装python守护程序包

Question

当我尝试安装python daemon软件包时，我一直都收到此错误（通过使用pip命令尝试下载并下载存档并使用pip进行安装）：

pip install python-daemon-2.1.2.tar.gz

Complete output from command python setup.py egg_info:

我是python的新手，搜索错误代码并使用其他线程提供的步骤并不能解决问题。

Answer 1

只需编写pip install python-daemon==2.1.2

使用pip从PyPI安装时，无需下载python-daemon-2.1.2.tar.gz文件。

如果要使用下载的软件包进行安装，请按照以下步骤操作

1. tar xvf python-daemon-2.1.2.tar.gz
2. cd python-daemon-2.1.2
3. python setup.py安装
