加载基本 Web 应用程序时的 Flask Temperamental

Question

我无法通过 Eclipse 和 Chrome 启动 Flask for Python 2.7；它太喜怒无常了，很难澄清它有效/无效的情况：

文件是 .project (Eclipse)、init.py 和 pymongo1.py

from flask import Flask 

app = Flask(__name__)

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

app.run(debug=True)

我加载 Eclipse，点击 Run 并获取：

pydev debugger: starting (pid: 5296)
Finding files... done.
Importing test modules ...  * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
* Restarting with stat
pydev debugger: starting (pid: 2312)
Finding files... done.
Importing test modules ... 

这简直就是手。在 Chrome 中，http://127.0.0.1:5000/ 或 127.0.0.1:5000/ 不会加载任何内容。将“索引页面”更改为“索引页面”并点击保存会给出

* Detected change in 'C:\\Users\\Eddie\\Desktop\\dev\\health\\pymongo1.py', reloading
127.0.0.1 - - [28/Sep/2015 14:57:49] "GET / HTTP/1.1" 200 -
pydev debugger: Start reloading module: "pymongo1" ... 
pydev debugger: Start reloading module: "pymongo1" ... 

..并保持 Chrome 加载。在 Eclipse 上点击 Run 然后给出：

pydev debugger: Start reloading module: "pymongo1" ... 
pydev debugger: Start reloading module: "pymongo1" ... 
 * Detected change in 'C:\\Users\\Eddie\\Desktop\\dev\\health\\pymongo1.py', reloading
pydev debugger: Start reloading module: "pymongo1" ... 
 * Detected change in 'C:\\Users\\Eddie\\Desktop\\dev\\health\\pymongo1.py', reloading

ERROR: Module: pymongo1 could not be imported (file: C:\Users\Eddie\Desktop\dev\health\pymongo1.py).   

尝试关闭其他应用以防它们在同一端口上运行，例如 Google 相册。任何线索为什么它会突然加载内容/似乎卡在“导入测试模块”部分？问候

由@riotburn 和@Joe Doherty 解决。需要从 Windows PowerShell 启动的 py 文件。
