在 Mahout 上安装 grouplens 数据时出现问题
通过链接安装mahout的任务（http://girlincomputerscience.blogspot.com /2010/11/apache-mahout.html)
在将 liberary 复制到 task-web 文件夹的过程中。我收到这样的错误..
因为
cp ../examples/target/grouplens.jar ./lib
error: cp: cannot stat 'cp ../examples/target/grouplens.jar' No such file or directory..
找不到 命令grouplens.jar 到目标文件夹..
提前致谢....

该消息的含义如下：文件
grouplens.jar不存在。您是否使用mvn install构建了代码？这是应该生成此 JAR 文件的前一步。 Mahout 是什么版本？The message means what it says: the file
grouplens.jardoes not exist there. Have you built the code withmvn install? that's a previous step that should generate this JAR file. What version of Mahout?您正在遵循本教程，但它已经过时了 - 您使用的是比教程本身更新版本的 mahout。
不管怎样，我也遇到了和你一样的情况，没有解决办法。不再进行编译或任何其他操作来创建
.jar文件。you are folowing the tutorial, but it is outdated - you were using newer versions of mahout than in the tutorial itself.
anyway, i also got stacked in the same position you were and there is no solution to it. no compilation or whatever will create the
.jarfile anymore.
