Flask找不到静态文件，因为文件缺失或URL路径错误。

English

Flask cannot find a static file because the file is missing or the URL path is incorrect.

generic

解决方案

  1. 95% 成功率 Place the file in the 'static' folder and use correct URL 
    mkdir static
mv style.css static/
# Access via /static/style.css
  2. 90% 成功率 Configure custom static folder 
    app = Flask(__name__, static_folder='assets')

无效尝试

常见但无效的做法:

  1. Placing static files in the templates folder 80% 失败

    Flask serves static files from a 'static' folder by default.

  2. Using absolute path in the URL 75% 失败

    Flask expects relative paths from the static folder.
