nc-config：安装netcdf后找不到命令

Question

我已经成功安装了netcdf-4.3.3.1-5.el7.x86_64。

 26: trait ViewVarsTrait
 27: {
     ...
/**
 52:      * Get the view builder being used.
 53:      *
 54:      * @return \Cake\View\ViewBuilder
 55:      */
 56:     public function viewBuilder()
 57:     {
 58:         if (!isset($this->_viewBuilder)) {
 59:             $this->_viewBuilder = new ViewBuilder();
 60:         }
 61: 
 62:         return $this->_viewBuilder;
 63:     }
     ...

但是当我尝试通过[root@localhost softwares]# yum install netcdf Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirror.mia11.us.leaseweb.net * centos-sclo-rh: mirror.netdepot.com * centos-sclo-sclo: mirrors.advancedhosters.com * epel: fedora-epel.mirror.lstn.net * extras: mirror.oss.ou.edu * updates: mirror.us.oneandone.net Package netcdf-4.3.3.1-5.el7.x86_64 already installed and latest version Nothing to do 查看netcdf的版本时，它说找不到命令。我正在使用centos 7。
