pip用于python包的安装,相似于Redhat下的yum、Ubuntu下的apt-get,能够解决安装包依赖的问题,很是方便。这里,咱们主要讲下windows下的配置。python
有多个路径能够配置pip,若是不存在该路径,能够自行建立。windows
只要pip命令中出现的选项均可以配置在配置文件中,好比直接输入pip命令,会提示如下选项,那么这些选项均可以卸载配置文件中。app
General Options: --log <path> Path to a verbose appending log. --proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port. --retries <retries> Maximum number of retries each connection should attempt (default 5 times). --timeout <sec> Set the socket timeout (default 120.0 seconds). --exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup. --trusted-host <hostname> Mark this host as trusted, even though it does not have valid or any HTTPS. --cert <path> Path to alternate CA bundle. --client-cert <path> Path to SSL client certificate, a single file containing the private key and the certificate in PEM format. --cache-dir <dir> Store the cache data in <dir>. --no-cache-dir Disable the cache. --disable-pip-version-check Don't periodically check PyPI to determine whether a new version of pip is available for download. Implied with --no-index.
这些选项是直接输入pip命令获得,因此归为General Options,在配置文件中,就要部署在global选项下,示例以下:socket
[global] index-url = http://pypi.douban.com/simple trusted-host = pypi.douban.com disable-pip-version-check = true timeout = 120
输入命令pip help install,就会提示pip install支持的全部选项,在配置文件中,就要部署在install选项下,示例以下:this
[install] ignore-installed = true no-dependencies = yes
pip支持install、download、uninstall、freeze、list、show、search、wheel、hash、completion等多条子命令,这些均可以分别配置。url
