我按照官方文档,安装了virtualenv和flask,然后python hello.py
但是出了点问题:
* Running on http://127.0.0.1:5000/
* Restarting with reloader: inotify events
Traceback (most recent call last):

AttributeError: type object 'EventsCodes' has no attribute 'IN_DELETE_SELF'
我的hello.py:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return "Hello World!"
if __name__ == '__main__':
app.run(debug=True)
但如果没有调试那可以吗?为什么? 我的/env/lib/python2.7/site-packages:
distribute-0.6.10-py2.7.egg
Jinja2-2.6-py2.7.egg
Werkzeug-0.7-py2.7.egg
easy-install.pth
pip-0.7.2-py2.7.egg
答案 0 :(得分:5)
这似乎是由pyinotify的API更改引发的错误,您必须安装它。您可以删除pyinotify或使用脏黑客强制它使用stat()而不是pyinotify。要werkzeug/serving.py
的第496行尝试添加(在尝试导入pyinotify的部分下方):
# dirty hack
reloader = _reloader_stat_loop
reloader_name = "stat() polling"
请务必向werkzeug开发人员报告错误。
