我是,使用Ubuntu 12.04服务器,默认情况下有两个版本的Python:2.7和3.2.当我使用python setup.py installterminal命令安装PIL时,PIL将与Python 2.7一起安装.如何使用Python 3.2安装PIL？因为我使用Python 3来编写我的脚本.如果我的Eclipse使用Python 2.7,则成功导入PIL.但如果我选择Python 3作为我的语法语言,PIL将无法导入.

P/S:我尝试过以下方法:

• 枕头PIL(Pillow-1.7.8.zip)
• Aspell PIL(PIL-1.1.7-py3-source.zip)

更新:

使用该python3命令会导致错误消息.

例1:

root@sys:~/Downloads/Pillow-1.7.8# python3.2 setup.py install
Traceback (most recent call last):
  File "setup.py", line 10, in <module>
    from setuptools import Extension, setup, find_packages
ImportError: No module named setuptools

例2:

root@sys:~/Downloads/Pillow-1.7.8# python3 setup.py install
Traceback (most recent call last):
  File "setup.py", line 10, in <module>
    from setuptools import Extension, setup, find_packages
ImportError: No module named setuptools

更新2

我运行此终端命令后

sudo apt-get install …

这是保存在web.config以下位置的连接字符串:

<appSettings>
    <add key="conn" value="Driver={MySQL ODBC 5.1 Driver};server=127.0.0.1;uid=root;pwd=1234;database=gis_server;option=3"/>
    </appSettings>

这是连接数据库的代码:

protected bool CheckPasswordBySqlServer(string strEmail, string strPsw)
{
    if (strEmail.ToLower() == "admin")
    {
        return false;
    }
    string str = "select id,Rank,RankEnc,ParentUser,Company from tbl_User where userName=@UserName and password1=@password";
    private string strConn = ConfigurationManager.AppSettings["conn"].ToString();
    SqlConnection sqlConnection = new SqlConnection(strConn);
    bool flag = false;
    try
    {
        try
        {
            sqlConnection.Open();
            SqlCommand sqlCommand = new SqlCommand(str, sqlConnection);
            sqlCommand.Parameters.AddWithValue("UserName", strEmail);
            sqlCommand.Parameters.AddWithValue("Password", strPsw);
            SqlDataReader sqlDataReader = sqlCommand.ExecuteReader();
            if (!sqlDataReader.Read())
            {
                flag = false;
            }
            else

 Ext.define('MyApp.view.MyVehicleGridPanel', {
   extend: 'Ext.grid.Panel',
   alias: 'widget.mygrid',
   header: false,
   store: UserStore,
   multiSelect: false,
   columns: [
                {
                    xtype: 'gridcolumn',
                    dataIndex: '_id',

                    text: 'Vehicle ID'
                },
                {
                    xtype: 'gridcolumn',
                    width: 126,
                    dataIndex: 'Plat_No',
                    text: 'Plat Number'
                },
                {
                    xtype: 'gridcolumn',
                    width: 200,
                    dataIndex: 'Name',
                    text: 'Added By'
                }
            ]
})

我在gridpanel中没有任何id声明,因为它会动态使用,
所以,我使用别名来查找我的网格组件,如下面的代码

var grid = Ext.ComponentQuery.query('mygrid');
        console.log( Ext.ComponentQuery.query('mygrid') );
        if (grid.getSelectionModel().hasSelection()) { //error at here 
           var row = grid.getSelectionModel().getSelection()[0];
           console.log(row.get('Plat_No'));
        };      

但是,firebug返回错误 TypeError: grid.getSelectionModel is not a function

任何其他方式来找到我的网格面板组件？

当我的MySQl数据类型为bit（1）时，但是用php打印时json_encode会用unicode写吗？IIS工作正常，
但是在我的专用服务器上，Apache托管将变为unicode。为什么？

您可以看到Locating，Locating在Mysql数据类型上是位，但打印\ u0001？为什么？

我收到此错误信息:

Error 1 Do not override object.Finalize. Instead, provide a destructor.

顺便说一句,这是由第三方公司遵守的原始代码.
如何解决这个问题呢？如何用覆盖结束？

我有一个选项卡面板,在加载网格面板时,用户可以切换选项卡和工具栏菜单.任何想法让用户在加载标签内容后禁用整页网站.用户只能访问其他组件.

这是我在加载数据存储时设置网格面板的方法:

grid.setLoading(true);

当页面加载网格时,网格只显示加载掩码,如何在加载选项卡页面时设置然后设置掩码.不是当页面加载网格时只启动掩码并等待数据存储获取数据.

车辆管理是我的默认标签页.
我的意思是当用户在网址中键入http://mywebsite.com然后有一个掩码时,等到车辆管理页面全部加载,然后取消屏蔽整个页面.当用户单击驱动程序管理器,然后再次屏蔽整个页面,等待所有页面加载后才取消屏蔽它.怎么做？
