Python 为什么我不'；安装pip软件包时，您没有删除六个的权限吗？

我已运行此命令来pip安装TensorFlow：

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

但是我在移除六个（无论如何重新安装它？）时遇到了问题

有人对这个问题有什么见解吗<代码>pip卸载六个也不起作用

我的终端正在吐出：

对于位置字段，确保您的

pip

为

python2.x

：

$ pip show pip

尝试在命令前面放置一个

sudo

。谢谢！每次我看到“拒绝许可”，我现在就知道可能是什么问题了@Alex如果我在命令“pip install something”前面使用sudo，那么包将安装在我的虚拟环境还是根环境中？

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