Python中在macOS系统安装requests库成功，但import时提示name 'request' is not defined如何解决？
用 pip 安装了 requests 库，下面是终端：
wujingyideMacBook:~ my$ sudo pip install requests Password: The directory '/Users/my/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. 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
Python中在macOS系统安装requests库成功，但import时提示name 'request' is not defined如何解决？
这个问题很常见，是因为代码里写错了导入的模块名。
requests 是一个第三方库，安装后应该用 import requests 来导入。你遇到的错误 name 'request' is defined，通常是因为你在代码里写成了 import request（少了一个’s’），或者直接使用了 request 这个变量但从未定义它。
解决方案：
-
检查你的代码，确保导入语句是：
import requests而不是
import request。 -
使用时，应该通过模块名
requests来调用它的方法，例如：import requests response = requests.get('https://api.example.com') print(response.status_code) -
如果你确实需要直接使用
request作为变量名，那需要从requests模块中导入特定的函数或对象，但这通常不是发起HTTP请求的标准做法。标准做法就是上面第2点。
总结： 确认代码里导入和使用的都是 requests（带s）。
