$ node -v
v0.6.14
$ ./server -t 02couchdb -s
The "sys" module is now called "util". It should have a similar interface.

运行教程
当你运行某个教程时,会提示一些错误:
复制代码 代码如下:
$ ./server 02couchdb
The "sys" module is now called "util". It should have a similar interface.
node.js:201
throw e; // process.nextTick error, or 'error' event on first tick
^

该教程包含很多依赖,我们需要使用 npm 来下载这些依赖的包。
安装 node 包
Node packages (dependencies) 可通过 npm 命令来安装,例如:
$ npm install optimist npm http GET https://registry.npmjs.org/optimist npm http 200 https://registry.npmjs.org/optimist npm http GET https://registry.npmjs.org/optimist/-/optimist-0.2.8.tgz npm http 200 https://registry.npmjs.org/optimist/-/optimist-0.2.8.tgz npm http GET https://registry.npmjs.org/wordwrap npm http 200 https://registry.npmjs.org/wordwrap npm http GET https://registry.npmjs.org/wordwrap/-/wordwrap-0.0.2.tgz npm http 200 https://registry.npmjs.org/wordwrap/-/wordwrap-0.0.2.tgz optimist@0.2.8 ../node_modules/optimist └── wordwrap@0.0.2
这些包将被安装到 node_modules 文件夹中:
$ ls -l ../node_modules/ total 0 drwxr-xr-x 10 ddewaele staff 340 Apr 1 18:54 optimist
本文需要安装如下的 node 包:
npm install winston npm install cradle npm install journey npm install optimist
运行教程
进入 bin 目录,通过下面命令来运行教程:
$ ./server -t 02couchdb -s The "sys" module is now called "util". It should have a similar interface. Pinpoint demo server listening for 02couchdb on :8000
然后打开浏览器访问 :8000/bookmarks ,将会看到如下的结果:
复制代码 代码如下:
{"bookmarks":[]}
这表示服务已经启动并运行,为了在 CouchDB 中添加点测试数据,我们可以使用 http-console 控制台来访问 CouchDB 的 REST 服务。
安装 http-console
有一个非常棒的工具可以帮助你调试服务,该工具名为 http-console ,你可使用 npm 来安装:
sudo npm install -g http-console
然后就可以在命令行中执行该工具,不幸的是当我们执行该命令时报错了:
$ http-console node.js:201 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: require.paths is removed. Use node_modules folders, or the NODE_PATH environment variable instead. at Function. (module.js:378:11) at Object. (/usr/local/lib/node_modules/http-console/bin/http-console:6:8) at Module._compile (module.js:441:26) at Object..js (module.js:459:10) at Module.load (module.js:348:31) at Function._load (module.js:308:12) at Array.0 (module.js:479:10) at EventEmitter._tickCallback (node.js:192:40)
很麻烦,我们还需要手工编辑 /usr/local/lib/node_modules/http-console/bin/http-console 文件,然后删除下面这一行:
复制代码 代码如下:
require.paths.unshift(path.join(__dirname, '..', 'lib'));
现在 http-console 就可以启动了,无需任何参数,它将连接到 :8080 ,如果你需要指定服务器和端口,把它作为第一个参数传递给 http-console 即可。
请注意我们这里使用了 \json 命令用来设置正确的 content-type:
