Question

当我尝试安装python daemon package时，我始终遇到此错误（通过使用pip命令安装并使用pip下载并使用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没有解决问题。

只需撰写pip install python-daemon==2.1.2

即可

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

tar xvf python-daemon-2.1.2.tar.gz
cd python-daemon-2.1.2
python setup.py install

python2.7使用pip安装python守护进程包
