＆＃34; AttributeError：＆＃39; NoneType＆＃39;＆＃34;每次我使用pip时出现

Question

我可以安装轮子，但不能使用＆＃34; pip install＆＃39;＆＃39;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆＃34;＆nbsp; / p>

错误

  

AttributeError：＆＃39; NoneType＆＃39;对象没有属性＆＃39; startswith＆＃39;

尽管存在张量流，但通常的模块如＆＃34;请求＆＃34;或者＆＃34; numpy＆＃34;不能通过点子安装。

如果你能看到图片我很感激：

Answer 1

您是否按照Anaconda通过pip安装tensorflow所需的步骤进行操作。仅pip install tensorflow：

似乎更精细

https://www.tensorflow.org/versions/r0.12/get_started/os_setup#anaconda_installation

Answer 2

对于它可能涉及的人，有这个重复的帖子，其中OP评论了这个问题的解决方案： Resolved duplicate

看起来，您的python路径“D：\ Anaconda3”可能与使用pip install的错误有关。尝试在“C：\”上安装python。

Answer 3

pip我遇到了同样的问题。结果是我的代理的格式不正确的网址，我错误地只使用了一个正斜杠：

http:/myproxy...

将上述内容更正为工作网址后，一切正常。
