dev_appserver.py没有这样的文件或目录

Question

我正在尝试启用发送中的电子邮件.所以我需要运行服务器.我在我的应用程序所在的名为"trade"的目录中.(参见pwd和ls)

Kenzos-MacBook-Pro:trade kenzotakahashi$ pwd
/Users/kenzotakahashi/desktop/main/WebDevelopment/project/trade
Kenzos-MacBook-Pro:trade kenzotakahashi$ ls
app.yaml    main.pyc    model.pyc   util.py
main.py     model.py    templates   util.pyc

但我得到了这个错误.

Kenzos-MacBook-Pro:trade kenzotakahashi$ dev_appserver.py trade

Kenzos-MacBook-Pro:trade kenzotakahashi$ 

这是我的app.yaml

application: trade
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /static
  static_dir: static

- url: /.*
  script: main.app

libraries:
- name: jinja2
  version: latest

- name: PIL
  version: "1.1.7"

我知道没有名为'trade'的文件但谷歌文件说"dev_appserver.py myapp"所以我认为'trade'将是myapp名称.我还尝试使用'main.py','main.app','main'来使用dev_appserver.py,但它们都没有用.我究竟做错了什么？

您需要在运行时指定路径dev_appserver.py.如果您从trade目录内部运行应用程序服务器,则可以运行其中一个

dev_appserver.py .

要么

dev_appserver.py ../trade

运行它的另一种方法是cd ..让你在包含trade然后运行的目录中

dev_appserver.py trade
