0.前言

经过前面几次的努力，我们基本上完成了环境中的搭建
本次我们解决一个基本上都会遇到的一个问题
那就是在WSL环境中运行python控制台调试django，控制台会报错： ModuleNotFoundError: No module named ‘xxx’

1.问题现象

其中的xxx是项目的名称，这里是csdntestdjango

/venv/csdntestdjango/bin/python /mnt/d/Program Files/JetBrains/PyCharm 2022.1.3/plugins/python/helpers/pydev/pydevconsole.py --mode=client --host=127.0.0.1 --port=41977

import django; print('Django %s' % django.get_version())

if 'setup' in dir(django): django.setup()
import django_manage_shell; django_manage_shell.run("F:/localgit/csdntestdjango")
PyDev console: starting.

ModuleNotFoundError: No module named 'csdntestdjango'

2. 问题分析

聚焦这两行

sys.path.extend(['F:\\localgit\\csdntestdjango', 'D:\\Program Files\\JetBrains\\PyCharm 2022.1.3\\plugins\\python\\helpers\\pycharm', 'D:\\Program Files\\JetBrains\\PyCharm 2022.1.3\\plugins\\python\\helpers\\pydev'])
if 'setup' in dir(django): django.setup()
import django_manage_shell; django_manage_shell.run("F:/localgit/csdntestdjango")

所有的路径都是Windows的路径，而非Linux路径，而我们的控制台实际上启动在WSL环境中

3. 解决办法

打开django控制台设置，添加路径映射

django控制台
映射的规则大致是F:盘对应/mnt/f,其他路径与windows一致，相当于将windows文件系统挂载到了WSL子系统中（用于运行程序）
路径映射
确定后重启python控制台，不再报该错误。但是报了新的错误，这个错误与外置配置文件相关，没有做外置文件配置的可忽略

其实这个问题之前我有另一篇帖子已经讲的很清楚了，这里不详细解释。
解决该问题非常简单只需要在django控制台设置中，正在启动脚本开头添加一句

import os; os.chdir([WORKING_DIR_AND_PYTHON_PATHS][0])

django控制台正在启动脚本
完成设置后，关闭django控制台，重新打开，完美运行。
这里需要注意一下，需要重新打开控制台，点击重新运行或者ctrl+F5没有任何作用。
