我有一个程序, 使用包件索引 < code> dateutil 。 我想设置. py check 来检查它的存在, 如果它不存在, 请尝试使用 < code> easi_ 安装 获取它 。
distutils _/a>的文件似乎表明,可以通过 sequips 关键词 () <() ,但当我尝试,它安装在一个没有 dateutil 的系统中,没有发出警告或安装所需的软件包。
在谷歌上我唯一能找到的就是,
我是否使用 distutils 错误? 我是否需要子类 distutils. command. host. attall 并自己检查/ 安装?
自动下载依附关系是setuptools ,这是对distutils 的第三方附加,特别是
另一个选项是使用aireasi_trement 作为软件安装器。 现已成为推荐的安装器;更多信息见 rel=“nofolpolt>Python包装用户指南 。
更新 [2015-01]:本答复的上一个版本提到 disprefitte fork 的 setuptools 。 dispreptrate fork 自那时以来已被合并回一个新的活动 settools 工程。 dispreditionte 现在已经不存在,应该不再使用。 setuptools 和 p>p > pip 现在得到了非常积极的维护和支持 Python 3。
设置函数 安裝 python settingup. py sdist 时, 才会有效 。
