Downloading/unpacking pyOpenSSL
Downloading/unpacking cryptography>=35.0 (from pyOpenSSL)
pip can't proceed with requirement 'cryptography>=35.0 (from pyOpenSSL)' due to a pre-existing build directory.
location: c:\users\17447\appdata\local\temp\pip_build_17447\cryptography
This is likely due to a previous installation that failed.
pip is being responsible and not assuming it can delete this.
Please delete it and try again.

是不是之前你安装过Python后来卸载了，然后又安装了别的版本到同一个位置？或者没有正常卸载？ hrpzcf 发表于 2022-9-18 15:16

安装卸妆好几遍了，但是这个版本只安装到这个位置了，应该没有冲突，我本来的python版本是3.9 ，这个是为了按照小甲鱼的按照步骤来安装的，版本是2.7.5 能删除的东西我都删除了 haitianodd 发表于 2022-9-18 15:54

旧版应该是没卸载干净，到程序卸载里看看有没有旧版没卸载的，卸载了，再把原来的安装路径、帖子里报错指示的路径删除干净，删除旧版的环境变量，安装新版本 新版教程步骤：
1、下载Miniconda
https://conda.io/minconda.html
下载对应的版本即可。
2、傻瓜式安装。
3、打开Anaconda Prompt，输入conda install -c conda-forge scrapy即可。（记得装回Python3） 小凯2013 发表于 2022-9-18 16:10

谢谢 我试试 或下载我这个，放在C:\Users\你的用户名\目录下，解压，再执行pip install scrapy
