"Permission denied" em arquivo temporário durante resolução do captcha

[ivanlonel]

Estou recebendo o seguinte erro nessa linha quando chamo download_country, download_state etc:

Traceback (most recent call last):

Parece que o pillow está chamando open() no arquivo que já foi aberto pelo NamedTemporaryFile, assim como nesse caso: https://stackoverflow.com/questions/23212435/permission-denied-to-write-to-my-temporary-file

O problema persiste?

Qual é a versão do sistema operacional? Python?

[ivanlonel]

Bom dia.

Sim, o problema persiste na versão 0.7.0.

Windows 11 Pro, 22H2 (22621.3007)

Python 3.11.5
Saída de sys.version:

Mesmo problema comigo. Instalei o módulo agora. Ou seja, a versão mais recente. E estou com o python 3.12.4.

Eu consegui fazendo essas seguintes alterações:

1 - Entre na biblioteca do SICAR e depois captcha.py
2 - Dentro do captcha.py localize as duas linhas

    with tempfile.NamedTemporaryFile(suffix=".png") as png:
        with tempfile.NamedTemporaryFile(suffix=".jpg") as jpg:

3 - Adicione o comando delete=False

    with tempfile.NamedTemporaryFile(suffix=".png",delete=False) as png:
        with tempfile.NamedTemporaryFile(suffix=".jpg",delete=False) as jpg:

4 - Salve o arquivo captcha.py .

Talvez resolva de forma provisória.
