用 pip 安装了 requests 库,下面是终端:

Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

上面显示安装成功后,在终端启用了 python,但是还是显示 name 'request' is not defined
wujingyideMacBook:~ my$ python Python 2.7.10 (default, Jul 15 2017, 17:16:57) [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)] on darwin Type "help", "copyright", "credits" or "license" for more information.
import requests r = request.get("http://www.baidu.com") Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'request' is not defined
下面这段是在 pycharm 里显示的错误:
import requests r = requests.get("http://www.baidu.com") r.status_code r.encoding = 'utf-8' r.text
Traceback (most recent call last): File "/Users/my/PycharmProjects/demo/learn.py", line 1, in <module> import requests ImportError: No module named requests
Process finished with exit code 1
但是在 pycharm 的 progect interpreter 里明明添加了 requests 库
本人用的是 mac,自带的 python2.7,目前安装了 pycharm oc,之前安装过 anaconda,又卸载了,不知道是不是电脑坏境有问题,求解

会不会是 pip 环境和 python 的执行环境不在一块?

第一个错是因为 request.get 拼错了,漏了 s。

另一个问题是 mac 下 pip 命令不需要 sudo,使用 sudo 反而可能造成权限问题。

wjjjj7 OP 拼写错误改了之后运行成功了,之后 pycharm 跑这段也莫名的不报错了,感谢感谢。虽然我还是觉得我的系统环境有问题,不过能用就行~

wjjjj7 OP @julyclyde 已经研究了两天了找不出环境的问题,只能靠 sudo 暂时解决库的安装问题,小白一只,以后多跟大神们学习 T T

我是用 brew 安装 python 的,命令上 python2+pip2, python3+pip3 分开,很好管理。
