[英]Why is mechanize not installing properly via pip on RPi? (python 3.9)
I can't get to successfully install the package 'mechanize' on a Raspberry Pi (so, ARM chip) with Debian Bullseye, python 3.9 in a virtualenv.我无法在虚拟环境中使用 Debian Bullseye、python 3.9 在 Raspberry Pi(因此,ARM 芯片)上成功安装包“mechanize”。
When I look in the virtualenv's sitepackages folder, indeed the mechanize package only has .dist-info
file, but not a mechanize.py
file or mechanize
package folder.当我查看 virtualenv 的 sitepackages 文件夹时,实际上 mechanize 包只有.dist-info
文件,但没有mechanize.py
文件或mechanize
包文件夹。 See below.见下文。
Question : Am I overlooking something?问题:我是否忽略了什么?

我找到了这个线程: https ://github.community/t/python-modulenotfounderror-although-module-is-installed-aiohttp/15425,这有帮助吗?
It appears to be an issue with version 0.4.8.这似乎是版本 0.4.8 的问题。 Installing version 0.4.7 works fine:安装 0.4.7 版可以正常工作:
pip install mechanize==0.4.7
as can be seen:可以看出:
