1、常用命令 -安装包 pip install packageName # 安装最新版本 pip install packageName==1.0.4 # 安装指定版本 pip install 'packageName>=1.0.4' # 指定安装的最小版本 注意：安装前会检查是否已安装该包，如果安装不管已安装的包高于或者低于即将安装的包，都会卸载后再安装想安装的包 （升级包时也是会先卸载原包，再安装升级包，所以个人认为好像不需要使用升级命令，需要哪个版本直接按版本号安装即可） -升级包#pip install -U（或--upgrade） packageName pip install -U packageName #升级到最新版本 pip install -U packageName==版本号 #指定升级的版本（版本可高于或低于当前版本） -卸载包 pip uninstall packageName -安装包到用户区 pip install --user packageName -通过配置文件安装多个对应版本的包(requiement.txt中的格式与pip freeze>requiement.txt格式一样) pip install -r requiement.txt -pip list #列出通过pip安装的包 -pip freeze #requirements format导出已安装的包 pip freeze > requiement.txt -pip --version 等同于 pip -V -pip --help 等同于 pip -h -pip show packageName #查看已安装包信息，包含信息如下 Name: xlrd Version: 1.2.0 Summary: Library for developers to extract data from Microsoft Excel (tm) spreadsheet files Home-page: http://www.python-excel.org/ Author: John Machin Author-email: sjmachin@lexicon.net License: BSD Location: d:frameworkspython37libsite-packages Requires: Required-by:
