python main.py --platform xhs --lt qrcode --type search 命令行执行时缺少库 import httpx ModuleNotFoundError: No module named 'httpx'

[dannishushu]

按照顺序执行，都没有问题，python版本是3.9.6

 cd MediaCrawler

 python -m venv venv
 
 source venv/bin/activate


 pip install -r requirements.txt


 playwright install
 

 python main.py --platform xhs --lt qrcode --type search

出现问题如下：

(venv) x@MacBook-Air PythonProject % python main.py --platform xhs --lt qrcode --type search
Traceback (most recent call last):
File "/Users/x/PycharmProjects/PythonProject/main.py", line 4, in

from .crawler_util import *
File "/Users/x/PycharmProjects/PythonProject/tools/crawler_util.py", line 11, in
import httpx
ModuleNotFoundError: No module named 'httpx'

在pycharm里debug模式没有问题，但命令行执行时python main.py 就会报错缺少httpx，可是httpx已经安装了，并且版本确实是0.24.0

这种问题请自查，不属于MediaCrawler仓库问题范畴。

非常不好意思

venv中从pip list来看是有http 0.24.0这个包的

又尝试单独安装 pip install httpx==0.24.0

可以看到也确实是安装在venv下的

把项目clone下来之后严格按照Readme的步骤执行的命令，运行不起来，可能会有人和我有一样的问题，我的意思如果能找到原因后续可以优化在Readme中

这个和仓库没有什么关系的，是你的mac系统python环境问题，你的虚拟环境虽然装了httpx且看起来进了虚拟环境，但是实际的运行的python不是你的虚拟环境的，临时解决方案：直接全局install，然后你要去谷歌搜索下你这个问题的解决方案。

多谢作者的认真负责

执行命令改为 ./venv/bin/python3.9 main.py --platform xhs --lt qrcode --type search 就没问题了

很奇怪，ls -l ./venv/bin/python3.9 显示python的位置在/Users/x/.pyenv/versions/3.9.6/bin/python3.9
系统环境变量明明也配置了alias， python -V 和 which python都显示就是用的/Users/x/.pyenv/versions/3.9.6/bin/python3.9

但如果不用./venv/bin/python3.9执行，确实是“实际的运行的python不是你的虚拟环境的”，奇怪
