次の場所から Google Go HelloWorld チュートリアルの作業を開始します。
https://developers.google.com/appengine/docs/go/gettingstarted/helloworld
MacBook Pro で OS X 10.8.2 を使用しています。
手順に従いましたが、最初のコード ( dev_appserver.py myapp/ ) を実行すると、質問の最後にエラーが表示されます。
これは、Hello World プログラムです。
package hello
import (
"fmt"
"net/http"
)
func init() {
http.HandleFunc("/", handler)
}
func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "Hello, world!")
}
これは構成ファイルです。
application: helloworld
version: 1
runtime: go
api_version: go1
ハンドラ:
- url: /.*
script: _go_app
ここでスタックオーバーフローをグーグルで検索しましたが、解決策が見つかりませんでした。
アイデアや提案があれば教えてください。

アップデート
api_version を 1 ( api_version: 1) に変更すると、役に立ちました。それでもエラー メッセージが表示されますが、サーバーは起動します。
それは今言う：
