pip install wheel
<1.进入c:\python\scripts的目录
<2. 在D:\Python27\Scripts目录下用管理员打开cmd,运行pip命令
pip install 包的名字.whl
当然也可以使用:
pip install C:\Users\xxx\Downloads\python_dateutil-2.5.3-py2.py3-none-any.whl
<3.安装成功后,出现Successfully .....
- <1.查看自已配置的环境,可以看看另一篇:环境变量
- <2.环境变量没问题,就使用在线安装。
例如:安装numpy ,命令:pip install numpy ,就成功啦。
- <1.使用 pip list 查看已安装的库,看好库的名称。
- <2. 使用 pip uninstall tensorflow-gpu ,就会把它卸载下来啦。(我是要安装cpu版本的,安装错啦卸载很简单)。
- <3 当然还有其他卸载方法 :
方法二:手工删除
去Python的第三方模块或包的存放位置进行手工删除文件和文件夹,然后删除easy-install.pth文件中的相应的行。
pip是一个很方便的工具, 可以方便安装, 列出, 卸载python的模块/库/包等
常见使用, 例如:
cmd下:
安装pycurl包
pip install pycurl
列出已经安装的python包
pip list
输出pycurl包的信息
pip show pycurl
卸载pycurl包
pip uninstall pycurl
