python - dev_appserver.py 没有那个文件或目录

Question

我正在尝试在开发中启用发送电子邮件。所以我需要运行服务器。我在我的应用程序所在的名为“交易”的目录中。(请参阅 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

但是我得到了这个错误。

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，但谷歌文档显示“dev_appserver.py myapp”所以我认为“贸易”将是我的应用程序名称。我还尝试过将 dev_appserver.py 与“main.py”、“main.app”、“main”一起使用，但它们都不起作用。我做错了什么？

Answer 1

运行dev_appserver.py时需要指定路径。如果您从 trade 目录中运行应用程序服务器，您可以运行任一

dev_appserver.py .

或

dev_appserver.py ../trade

另一种运行它的方法是cd .. 所以你在包含trade 的目录中然后运行

dev_appserver.py trade
