尝试在 python 中保存文件后出现错误

Question

几周前我开始学习 Python，所以我可以制作这个项目，将所有图像保存在多个网页上。除了最后几行外，一切正常，我收到一条错误消息：

File "/Users/hitchhiker/Desktop/manga_yoinker/main.py", line 36, in <module> with open(filename, "wb") as file: FileNotFoundError: [Errno 2] No such file or directory: 'page/cropped-Jujutsu_kaisen-324x324-1.png'

代码如下：

import os
import requests
from bs4 import BeautifulSoup
import shutil

link = "https://kaisenscans.com/chapter/jujutsu-kaisen-chapter-"

main_dir = os.path.join("/Volumes/flash", "main_folder")
os.mkdir(main_dir)

for chapter_number in range(1, 2):
    chapter = link + str(chapter_number)
    page = requests.get(chapter)
    chname = "chapter"+str(chapter_number)

current_dir = "/Users/hitchhiker/Desktop/manga_yoinker/" + chname
destination = "/Volumes/flash/main_folder"

dire = os.mkdir(chname)

shutil.move(current_dir, main_dir)

soup = BeautifulSoup(page.content, "html.parser")
imgs = soup.find_all("img")


for img in imgs:
    img_link = img.attrs.get("src")
    image = requests.get(img_link).content
    filename = "page" + img_link[img_link.rfind("/"):]

    with open(filename, "wb") as file:
        file.write(image)

我在谷歌上搜索了解决方案，但似乎找不到任何适合我的问题。

解释在错误中：

FileNotFoundError: [Errno 2] No such file or directory: 'page/cropped-Jujutsu_kaisen-324x324-1.png'

没有更多细节，我认为目录page/ 不存在。你能检查一下吗？

open() 将创建 文件，如果它不存在但不存在父目录。

如果这是问题所在，您可以像这样自动创建它：

dir = './page/'
os.makedirs(dir, exist_ok=True)
# Equivalent to :
# if (not os.path.isdir(dir)):
#    os.mkdir(dir)
