```

## 问题:
我成功了安装了cmake, 并且在PATH下:
```
[root@aa1890dac708 xlearn-0.40a1]# cmake --version
cmake version 3.13.2

[root@2abf73ae1a0a /]# which cmake
/usr/sbin/cmake
[root@2abf73ae1a0a /]# echo $PATH
/opt/conda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
```

在安装xlearn的时候出现异常,提示cmake未安装

```

## 排查过程

1. 怀疑cmake, 安装的有问题, 用pip重新安装了一下
```
 pip install --no-cache-dir cmake -i https://mirrors.aliyun.com/pypi/simple/
```
没什么卵用

2. 网络上有相同问题, 因为gcc版本过高, 将之从 8.2.1 降到 7.4.1
```
