我使用的是Mac,Python版本是2.7.10。我安装了烧瓶

â  Flask_blog python Python 2.7.10 (default, Oct  6 2017, 22:29:07) 
[GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import flask
>>>

我试着学习flash on的教程 http://flask.pocoo.org/docs/1.0/

命令:

â  Flask_blog export FLASK_APP=flaskblog.py
â  Flask_blog flask run                    
zsh: command not found: flask
â  Flask_blog

flaskblog.py中的代码:

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

错误是 command not found: flask

我还尝试了另一个教程。

命令:

â  Flask_blog cd /Users/jzd/Movies/flask/Second_video 
â  Second_video python one.py                           
Sorry

在one.py中编码

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return 'Hello World'

if __name__ == '__name__':
    app.run('0.0.0.0')
else:
    print("Sorry")

条件 __name__ == '__name__':

venv

真想知道怎么修。
