Traceback (most recent call last): File "E:\pythonProject1\venv\test.py", line 1, in <module> import requests ModuleNotFoundError: No module named 'requests'

这个错误是因为你的 Python 环境中没有安装 requests 模块导致的。你需要使用以下命令来安装 requests 模块: ``` pip install requests ``` 如果你使用的是 Python 3,可能需要使用以下命令: ``` pip3 install requests ``` 安装完成后,你就可以在 Python 中使用 requests 模块了。

Traceback (most recent call last): File "C:\Users\86150\Desktop\pythonProject\venv\招聘信息爬取\test.py", line 13, in <module> By.CSS_SELECTOR , NameError: name 'By' is not defined

这个错误提示意味着 Python 找不到名为 `By` 的变量。通常情况下,`By` 是 Selenium 中的一个常量,指定了查找元素的方式,可能是 `By.ID`、`By.XPATH`、`By.CSS_SELECTOR` 等等。解决这个错误的方法是在代码中导入 `By`,可以尝试在代码开头添加以下语句: ```python from selenium.webdriver.common.by import By ``` 这样就可以在代码中使用 `By` 常量了。如果还有其他问题,请告诉我。

E:\PythonProjects\test\venv\Scripts\python.exe E:\PythonProjects\test\test.py E:\PythonProjects\test\venv\Lib\site-packages\paramiko\transport.py:202: CryptographyDeprecationWarning: Blowfish has been deprecated "class": algorithms.Blowfish, Traceback (most recent call last): File "E:\PythonProjects\test\test.py", line 1, in <module> import paramiko File "E:\PythonProjects\test\venv\Lib\site-packages\paramiko\__init__.py", line 32, in <module> from paramiko.client import ( File "E:\PythonProjects\test\venv\Lib\site-packages\paramiko\client.py", line 35, in <module> from paramiko.hostkeys import HostKeys File "E:\PythonProjects\test\venv\Lib\site-packages\paramiko\hostkeys.py", line 23, in <module> from collections import MutableMapping ImportError: cannot import name 'MutableMapping' from 'collections' (E:\Python\Lib\collections\__init__.py)怎么改错

这个错误是由于在paramiko模块中的hostkeys.py文件中导入了collections模块的MutableMapping时出错。这个问题可能是由于Python版本不兼容导致的。 要解决这个问题,你可以尝试以下几种方法: 1. 确保你使用的Python版本符合paramiko模块的要求。你可以查看paramiko模块的文档或者官方网站了解它所支持的Python版本。 2. 如果你的Python版本符合要求,但仍然出现这个错误,那么可能是因为你的Python环境中的collections模块没有MutableMapping属性。这可能是因为Python版本较旧,没有这个属性。 - 如果你使用的是Python 2.x版本,可以尝试将`from collections import MutableMapping`改为`from collections.abc import MutableMapping`。 - 如果你使用的是Python 3.x版本,可以尝试将`from collections import MutableMapping`改为`from collections.abc import MutableMapping`或者`from collections import MutableMapping`。 3. 如果上述方法都不起作用,你可以尝试更新paramiko模块到最新版本,使用命令`pip install --upgrade paramiko`来更新。 希望这些方法能够帮助你解决问题!如果还有其他疑问,请告诉我。
