我为自己的无知道歉 - 我对此很新 - 但我已经尝试了一切,并且无法使用RVM安装1.9.2.我相信我已经正确安装了RVM,当我去安装1.9.2时,当ruby尝试编译时,我的make日志中出现以下错误:

ld: in /usr/local/lib/libz.1.dylib, file was built for unsupported file format which is   
not the architecture being linked (x86_64) for architecture x86_64
collect2: ld returned 1 exit status
make[1]: *** [../../../.ext/x86_64-darwin10.6.0/digest/md5.bundle] Error 1
make: *** [mkmain.sh] Error 1

其他一些信息:我在32位运行OS X,并收到类似的错误 - 用我认为(i36)替换(x86_64).我现在以64位运行.

*更新*:

我已经完成了TinMan要求我做的所有事情,但仍无济于事 - 只想指出我可以安装1.8.7就好了.试图安装1.9.1和1.9.2给出了以下错误消息:

一般是Android和Java的新手,我正在学习如何进行JSON调用.为此,我正在遵循本指南:http://mobiforge.com/design-development/consuming-json-services-android-apps

这就是让我感到困惑的地方.该教程的作者希望读者调用此API:http://ws.geonames.org/findNearByWeatherJSON？ la = 37lng = 122

以这种格式返回JSON对象:

            {
                "weatherObservation": {
                     "clouds":"scattered clouds",
                     "weatherCondition":"n/a",
                     "observation":"KCFV 090852Z AUTO 06005KT 
                      10SM SCT090 SCT110 24/20 A3000 RMK AO2 
                      SLP148 T02390200 53002",
                     "windDirection":60,
                     "ICAO":"KCFV",
                     "seaLevelPressure":1014.8,
                     "elevation":225,
                     "countryCode":"US",
                     "lng":-95.56666666666666,
                     "temperature":"23.9",
                     "dewPoint":"20",
                     "windSpeed":"05",
                     "humidity":78,
                     "stationName":"Coffeyville, Coffeyville 
                                 Municipal Airport",
                     "datetime":"2012-07-09 08:52:00",
                     "lat":37.083333333333336
                }
            }

非常简单,除了API不再有效/有限制.为了完成项目,我选择调用此API:http://api.openweathermap.org/data/2.5/weather？la = 37.77&rn = 1222.419

以这种格式返回JSON

{
    "coord": {
        "lon": 139,
        "lat": 35
    },
    "sys": {
        "country": "JP",
        "sunrise": 1369769524,
        "sunset": 1369821049
    },
    "weather": …
