pip安装python包的一些常见错误及解决方法

  • 错误:xarray 0.15.0 has requirement numpy >=1.15, but you will have numpy 1.14.0 which is incompatible
    解决:因为不兼容,需要升级numpy包。 pip install -U numpy

  • 错误:Could not install packages due to anEnvironmentError:[WinError 5]拒绝访问
    解决:只需在install后加上–user即可。例如要升级numpy包,pip install -U numpy出现上述错误,应改为pip install --user -U numpy

  • 错误:Could not find a version that satisfies the requirement skimage (from versions: )
    解决:这是因为网络的问题,需要使用国内的镜像源来加速。
    命令后面加上 -i https://pypi.tuna.tsinghua.edu.cn/simple
    或者-i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

  • 错误:ImportError: Missing required dependencies [‘numpy’]
    解决:卸载重装,即:
    pip uninstall pandas
    pip uninstall numpy
    pip install pandas
