Windows上的Python以‘`AttributeError:模块’集合‘没有属性’可调用‘开始
提问于 2022-10-11 20:58:18
只需在windows上安装python 3，并使用命令"python“在终端上启动它。然后我犯了一个错误：
C:\Users\User>python

我不明白为什么我会犯这个错误。

造成此问题的原因是pyreadline安装时将过时的包作为可导入的包呈现出来。由于这为Windows提供了readline模块，默认的site模块将能够导入它并触发错误。这个过时且不再维护的包试图从不推荐的位置collections.abc.Callable ( collections.Callable，它将在Python3.10下失败 )导入完全移除，因为被废弃的导入已经是完全移除了。
要解决这个问题，只需卸载pyreadline包，如果需要由readline提供的功能，则安装pyreadline3包，该软件包目前正在维护(2022年)，并将提供该软件包所期望的功能。
请务必确保在安装pyreadline之前先卸载pyreadline3
C:\Users\User>python -m pip uninstall pyreadline
Found existing installation: pyreadline 2.1
Uninstalling pyreadline-2.1:
Would remove:
c:\users\user\appdata\local\programs\python\python310\lib\site-packages\pyreadline-2.1-py3.10.egg-info

c:\users\user\appdata\local\programs\python\python310\lib\site-packages\readline.py

>>>请注意，如果pyreadline和pyreadline3包同时安装在相同的readline环境/安装中，则可能会发生包冲突，因为这两个包都提供了readline模块。
或者，按照这句话的建议去做，这是在关于BeautifulSoup的问题下发布的，因为还有其他被广泛使用的Python包没有及时纠正这个不推荐的导入。

试一试
BeautifulSoup AttributeError 'collections‘没有属性’可调用‘
Navigate to Python310\Lib\site-packages\pyreadline in your file browser.
Open py3k_compat.py in an text editor.
Change the 8th line from which should be return isinstance(x, collections.Callable) to return isinstance(x, collections.abc.Callable).
Save, exit and then retry.或者重新安装python
