英文:
AppEngine/Go app won't compile. What did I miss?
问题
我正在尝试测试一个AppEngine/Go应用程序。我启动dev_appserver.py并开始提供应用程序，但是当我在浏览器中输入localhost:8080时，我得到以下错误信息：
编译错误：
/home/adam/foobar/server/app/server.go:5: 找不到导入：appengine/users
2011/08/23 19:45:34 go-app-builder: 构建应用程序失败：运行8g失败：退出状态1
我感觉我需要做一些事情，以使AppEngine特定的库在GO期望它们存在的位置可用，但是我真的不想在AppEngine/Go SDK压缩包中的所有内容上运行goinstall，对吗？我似乎错过了一个安装步骤，但是就我而言，我无法找到明智和正确的做法。
我使用的是Ubuntu，如果这有关系的话。
英文:
I am trying to test an AppEngine/Go application. I start dev_appserver.py and it begins serving the application, but when I go to localhost:8080 in my browser, I get:
Compile error:
/home/adam/foobar/server/app/server.go:5: can't find import: appengine/users
2011/08/23 19:45:34 go-app-builder: Failed building app: failed running 8g: exit status 1
I feel as though I need to do something to make the AppEngine-specific libraries available where GO expects them to be, but I don't really want to run goinstall on everything that comes in the AppEngine/Go SDK zip, do I? I seem to have missed an installation step, but for the life of me, I can't figure the sane and right thing to do.
I am on Ubuntu, if that matters.

用户API不是appengine/users，而是appengine/user。从App Engine页面的示例中可以看到：
import (
"appengine"
"appengine/user"
)
func welcome(w http.ResponseWriter, r *http.Request) {
c := appengine.NewContext(r)
u := user.Current(c)
if u == nil {
url := u.LoginURL(c, "/")
fmt.Fprintf(w, `<a href="%s">登录或注册</a>`, url)
return
}
url := user.LogoutURL(c, "/")
fmt.Fprintf(w, `欢迎，%s！(<a href="%s">退出</a>)`, u, url)
}
英文:
The Users API isn't appengine/users - it's appengine/user. From the example on the App Engine page:
import (
"appengine"
"appengine/user"
)
func welcome(w http.ResponseWriter, r *http.Request) {
c := appengine.NewContext(r)
u := user.Current(c)
if u == nil {
url := u.LoginURL(c, "/")
fmt.Fprintf(w, `<a href="%s">Sign in or register</a>`, url)
return
}
url := user.LogoutURL(c, "/")
fmt.Fprintf(w, `Welcome, %s! (<a href="%s">sign out</a>)`, u, url)
}

你不需要自己编译代码 - 只需运行dev_appserver，它会在代码更改时为您编译。您是否已经阅读了入门文档？
英文:
You don't have to compile the code yourself - just run the dev_appserver and it will compile it for you whenever the code changes. Have you gone through the getting started docs?
