无法从“werkzeug”导入名称“secure_filename”

Question

我试图从werkzeug.utils导入secure_文件名，但它出现了一个错误。它在我的基础虚拟环境下运行良好

代码：

# Flask packages
from flask import Flask, render_template, request, session, redirect, flash, send_file
from flask_bootstrap import Bootstrap 
from flask_uploads import UploadSet,configure_uploads,IMAGES,DATA,ALL

# Systems
import os 
import sys
import json
from werkzeug.utils import secure_filename

错误：

    (absa_annotation) C02QM3FSFVH3:ABSA-annotation-tool kwunkeilau$ python3 app.py 
Traceback (most recent call last):
  File "app.py", line 4, in <module>
    from flask_uploads import UploadSet,configure_uploads,IMAGES,DATA,ALL
  File "/Users/kwunkeilau/anaconda3/envs/absa_annotation/lib/python3.7/site-packages/flask_uploads.py", line 26, in <module>
    from werkzeug import secure_filename, FileStorage
ImportError: cannot import name 'secure_filename' from 'werkzeug' (/Users/kwunkeilau/anaconda3/envs/absa_annotation/lib/python3.7/site-packages/werkzeug/__init__.py)

除了上述建议的解决方案之外，您还可以使用维护良好的fork Flask-Reuploaded

您甚至不必更改import语句，因为它试图与不再维护良好的Flask-Uploads保持兼容

见https://github.com/jugmac00/flask-reuploaded

另外，Flask-Reuploaded当然在PyPI上提供了最新的包：
