Question

我在mac上使用app.run(debug=True)运行以下代码。我可以在debug=False时运行代码并测试应用程序，但是当我尝试使用debug=True时，我收到以下错误：

Traceback (most recent call last):

  File "/anaconda3/lib/python3.6/site-packages/IPython/utils/py3compat.py", line 186, in execfile
    exec(compiler(f.read(), fname, 'exec'), glob, loc)

  File "/flaskhello.py", line 42, in <module>
    app.run(host='0.0.0.0', port = 5004, debug = True)

  File "/anaconda3/lib/python3.6/site-packages/flask/app.py", line 841, in run
    run_simple(host, port, self, **options)

  File "/Users/DGS-Mkt/anaconda3/lib/python3.6/site-packages/werkzeug/serving.py", line 737, in run_simple
    reloader_type)

  File "/Users/DGS-Mkt/anaconda3/lib/python3.6/site-packages/werkzeug/_reloader.py", line 265, in run_with_reloader
    sys.exit(reloader.restart_with_reloader())

SystemExit: 1

以下是代码：

from flask import Flask, render_template

app = Flask(__name__)
questions = ['Is it compiled?', 'Does it run on a VM?']
guesses = ['Python', 'Java', 'C++']


@app.route('/')
def index():
    return render_template('index.html')


@app.route('/question/<int:id>')
def question(id):
    return render_template('question.html', question=questions[id])


@app.route('/guess/<int:id>')
def guess(id):
    return render_template('guess.html', guess=guesses[id])


if __name__ == '__main__':
    app.run(debug=True)

我认为问题不是在mac上运行烧瓶。也许你在anaconda有一些问题。我向你建议的2个解决方案：

hibernate.hbm2ddl.auto

或者您可以从anaconda卸载软件包

app = Flask(__name__)
app.config['DEBUG'] = True

并使用pip

进行安装

conda remove flask
conda remove werkzeug

来源：Flask debug not working under Anaconda

Flask调试器未在Mac上运行
