Question

我有一个rails应用程序，我最近推送到'生产'VPS托管服务器。我使用Capistrano进行部署，它似乎已经很好地服务于服务器了。我更改了应用程序的当前目录并运行了bundle install以开始设置所有内容并点击此错误：

public class NavigationDrawerFragment extends Fragment implements GookAdapter.ClickListener {
private GookAdapter adapter;
private RecyclerView recyclerView;
public static final String PREF_FILE_NAME="testpref";
public static final String KEY_USER_LEARNED_DRAWER="user_learned_drawer";
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;
private boolean mUserLearnedDrawer;
private boolean mFromSavedInstanceState;
private View containerView;

public NavigationDrawerFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mUserLearnedDrawer = Boolean.valueOf(readFromPreference(getActivity(), KEY_USER_LEARNED_DRAWER,"false"));
    if(savedInstanceState!=null){
        mFromSavedInstanceState=true;
    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View layout = inflater.inflate(R.layout.fragment_navigation_drawer, container, false);
    recyclerView= (RecyclerView) layout.findViewById(R.id.drawerList);
    adapter = new GookAdapter(getActivity(), getData());
    adapter.setOnClickListener(this);
    recyclerView.setAdapter(adapter);
    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
    return layout;
}

public static List<Information> getData(){
    List<Information> data = new ArrayList<>();
    int[] icons = {R.drawable.home,
                    R.drawable.reminder,
                    R.drawable.importdata,
                    R.drawable.exportdata,
                    R.drawable.settings};
    String [] titles = {"New Transaction", "Reminder", "Import Data", "Export Data", "Category Setting"};
    for (int i=0;i<titles.length && i<icons.length;i++){
            Information current = new Information();
            current.iconId=icons[i%icons.length];
            current.title=titles[i%titles.length];
            data.add(current);
     }
    return data;
}


public void setUp(int fragmentId, DrawerLayout drawerLayout, Toolbar toolbar) {
    containerView=getActivity().findViewById(fragmentId);
    mDrawerLayout = drawerLayout;
    mDrawerToggle= new ActionBarDrawerToggle(getActivity(), drawerLayout, toolbar, R.string.drawerOpen, R.string.drawerClose){
        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            if(!mUserLearnedDrawer){
                mUserLearnedDrawer=true;
                savedToPreferences(getActivity(), KEY_USER_LEARNED_DRAWER, mUserLearnedDrawer+"");
            }
            getActivity().invalidateOptionsMenu();

        }

        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
            getActivity().invalidateOptionsMenu();
        }
    };

    if(!mUserLearnedDrawer && !mFromSavedInstanceState){
        mDrawerLayout.openDrawer(containerView);
    }
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    mDrawerLayout.post(new Runnable() {
        @Override
        public void run() {
            mDrawerToggle.syncState();
        }
    });
}



public static void savedToPreferences(Context context, String preferenceName, String preferenceValue){
    SharedPreferences sharedPreferences = context.getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putString(preferenceName, preferenceValue);
    editor.apply();
}

public static String readFromPreference(Context context, String preferenceName, String defaultValue){
    SharedPreferences sharedPreferences = context.getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE);
    return sharedPreferences.getString(preferenceName, defaultValue);
}

@Override
public void itemClicked(View view, int position) {
    if(position == 0){
        startActivity(new Intent(getActivity(), NewTransaction.class));
        getActivity().finish();
    }else if(position == 1){
        startActivity(new Intent(getActivity(), Reminder.class));
        getActivity().finish();
    }else if(position == 2){
        startActivity(new Intent(getActivity(), Reminder.class));
        getActivity().finish();
    }else if(position == 3){
        startActivity(new Intent(getActivity(), Reminder.class));
        getActivity().finish();
    }else{
        startActivity(new Intent(getActivity(), CategorySetting.class));
    }

}

我不熟悉这个错误，对我来说这是一个未知的领域，所以我有点失落。我能够在服务器soure code

上获得postgres

我很确定这是一个简单的解决方案，我只是不熟悉设置新服务器，所以我不确定我在这里做什么！

编辑：

如下所示，我将lib和dev包添加到我的服务器。我在Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /usr/local/rvm/rubies/ruby-2.2.1/bin/ruby -r ./siteconf20151105-8574-y7clqw.rb extconf.rb checking for pg_config... no No pg_config... trying anyway. If building fails, please try again with --with-pg-config=/path/to/pg_config checking for libpq-fe.h... no Can't find the 'libpq-fe.h header *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.找到了pg_conf，但我的应用程序似乎无法找到它，导致上面的错误。当我按照上面的错误输出中的建议尝试执行/usr/pgsql-9.3/bin时，我收到$ bundle install --with-pg-config=/usr/pgsql-9.3/bin错误。

我应该如何映射到文件？还有其他事情发生在这里，我不理解吗？

ssh到您的生产机器并在该机器上安装postgresql-devel包，这将解决pg_config missing的问题：

sudo apt-get install libpq-dev

生产服务器上的捆绑安装失败
