我通过brew在mac os x 10.10上安装了mahout，但在ubuntu上遇到了同样的问题。在web上，我只能找到关于eclipse的教程，但我想通过终端运行它

未找到MAHOUT\u CONF\u DIR

添加到.bash_配置文件或.zshrc：

```
export-MAHOUT=/path/to/MAHOUT
```

export-MAHOUT\u CONF\u DIR=$MAHOUT\u HOME/CONF

为了在本地运行Mahout 添加到.bash_配置文件或.zshrc：

export MAHOUT\u LOCAL=“非空字符串”

设置为空字符串以外的任何值以强制mahout在本地运行
即使设置了

HADOOP\u CONF\u DIR

和

HADOOP\u HOME

为了快速启动和运行，我建议您：

下载mahout作为
```
tar.gz
```
：
按照前面提到的步骤1和步骤2操作，
```
/path/to/mahout
```
是您提取
```
mahout-distribution-0.9
```
从
```
mahout-distribution-0.9/bin/mahout
```

i、 e:

/bin/mahout recommenditembased-i'/Users/lorenzoferri/Desktop/prova1.csv'-o'/Users/lorenzoferri/Desktop/output.csv'-n 100-s相似性\u coccurrence

在
```
mahout-distribution-0.9/examples
```
中，您可以运行和浏览一些shell脚本

将$MAHOUT\u HOME设置为什么？指向提取的tar.gz，例如

$MAHOUT\u HOME=~/machine\u learning/MAHOUT-distribution-0.9
