Причина: не удалось удалить каталог `C:\Users\USERNAME\AppData\Local\uv\cache\builds-v0\.tmpE7rqrS\Lib\site-packages\pywin32-311.data`: процесс не может получить доступ к файлу, поскольку он используется другим процессом. (ошибка ОС 32)
Мой процесс:
Я создал токен в HA и в Claude > Settings > Developer > Edit Config, вставил json mcPServers в файл конфигурации под разделом настроек, чтобы файл выглядел так.
Мой файл claude_desktop_config.json находится в:
{
"mcpServers": {
"home-assistant": {
"command": "uvx",
"args": [
"ha-mcp"
],
"env": {
"HA_URL": "https://192.168.xx.XXX:8123",
"HA_TOKEN": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
}
}
},
"preferences": {
"coworkScheduledTasksEnabled": true,
"ccdScheduledTasksEnabled": true,
"sidebarMode": "task",
"coworkWebSearchEnabled": true
}
}
Где HA_URL — это мой внутренний IP-адрес HA.
А HA_TOKEN — это токен.
Я сохраняю этот файл, затем перезапускаю Claude, выбрав «Файл» > «Выход».
Затем отправляюсь в «Настроить» > «Соединители» > «Home Assistant» > «Подключиться» и нажимаю «Подключиться».
Откроется браузер и спросит, хочу ли я открыть Claude. Я нажимаю кнопку «Открыть» и получаю ошибки:

I've closed Claude & deleted the cache directory:
C:\\Users\\USERNAME\\AppData\\Local\\uv\\cache\\builds-v0
Checked Task Manger & Sys Internals both show no Python process running (In Process Manager I searched for the pywin32 handle. Nothing.
Rebooted
Disabled my Window AV
Ran uv cache clean
Ran Claude as admin
Posted here on Reddit
What are my next steps?
I've got pyCharm installed but not running so it shouldn't be locking. Kinda run out of ideas.
Thanks for your help.
