为什么我在安装 pip 包时没有删除六个的权限?

Why I don't have permissions to remove six while installing a pip package?

我已经 运行 这个命令来 pip 安装 TensorFlow:

pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

但是我在删除六个时遇到问题(无论如何都要重新安装?)

有没有人对这个问题有任何见解。 pip uninstall six 也不行

我的终端吐出:

确保 pip 对于 location 字段是 python2.x
