node.jsを起動してみる

投稿日 2013年10月30日 23:53 by おっとっとっと

windows版をインストールすると
環境変数PATHに２つパスが追加されている。
コマンドプロンプトで確認すると
C:\Users\{ユーザ名}>echo %PATH%
C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\Wind
owsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;
C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\nodejs\;C:\Use
rs\{ユーザ名}\AppData\Roaming\npm
となっているので、
C:\Users\{ユーザ名}>node
>
で、準備OK。
しかし
> node -v
ReferenceError: node is not defined

>(Ctrl+Dで終わる)
そうそう
C:\Users\{ユーザ名}>node　-v
v0.11.7
C:\Users\{ユーザ名}>npm -v
1.3.8
C:\Users\{ユーザ名}>
なのだ。
さてデバッガをインストールしてみよう。

C:\Users\{ユーザ名}>npm -g install node-inspector

まだ、開発バージョンのせいだろう。
３回コマンドを繰り返えしたら成功した。
C:\Users\{ユーザ名}>npm -g install node-inspector

では何か動かしてみよう

C:\Users\{ユーザ名}にこんなhellow.jsを作ってみる。
var http = require('http');
var server = http.createServer(function(req, res){
   res.writeHead(200, {'Content-Type': 'text/plain'});
   res.write('Hello World\n');
   res.end();
});
server.listen(3000);
C:\Users\{ユーザ名}>node --debug hellow.js
debugger listening on port 5858
と出るので、ブラウザ(FireFox)から http://127.0.0.1:5858/ を見ると、
Type: connect
V8-Version: 3.20.17
Protocol-Version: 1
Embedding-Host: node v0.11.7
Content-Length: 0

しか出ない。
コマンドプロンプトには
GET / HTTP/1.1: (no value)
Host: 127.0.0.1:5858
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:24.0) Gecko/20100101 Firefo
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: ja,en-us;q=0.7,en;q=0.3
Accept-Encoding: gzip, deflate
Connection: keep-alive
Cache-Control: max-age=0
とログが出た。
では、デバッガを起動し、

C:\Users\{ユーザ名}>node-inspector
Node Inspector v0.5.0
info  – socket.io started
Visit http://127.0.0.1:8080/debug?port=5858 to start debugging.

ブラウザ(FireFox)から http://127.0.0.1:8080/debug?port=5858 を見ると、

node.jsのデバッガ画面
node.jsのデバッガ画面



とソレっぽい画面は出てくるものの何も出ない。（大笑
とりあえず、IDEっぽいものは既にあるようだ。
説明ページもあったが、
Windowsではまだまだのようだ。
デバッガが
lob error { [Error: EPERM, readdir ‘C:\Users\{ユーザ名}\AppData\Local\Microsoft\Windows
INetCache\Content.IE5’]
errno: -4049,
code: ‘EPERM’,
と延々とパスをサーチしてしまう。
次はCentOS6でやってみよう。
