安装eclipse python 插件pyDev问题解决方法

1  方法：在线安装，打开eclipse，选择help --》install new software ，弹出Available Software窗口，输入pyDev在线安装地址： http://pydev.org/updates，工具会去其地址下载插件并安装，在我机器上默认选择了最新可用版本，安装了好几次都失败了，会报出形如：

的错误，大致错误是处理jar文件签名的时候发生过了一个错误，解决方法是不要选择最新可用版本，选择2.8.0那一版这个错误不会出现了，错误步骤：在Available Software窗口，把"show only the latest versions of available software"前面的对勾勾掉，选择2.8.0这一版，下面的按照安装向导一步一步走下去就安装完毕了
