运行命令 Cmake 时权限被拒绝

我正在使用 Ubuntu 20.04。当我运行命令时，cmake --version出现权限被拒绝错误，如下所示：

 :
Traceback (most recent call last):
  File "/usr/local/bin/cmake", line 11, in <module>

在这里以普通用户和 root 用户身份从 Ubuntu 源安装。

zeus@zeus-H370M:~$ which cmake
zeus@zeus-H370M:~$
zeus@zeus-H370M:~$ su

zeus@zeus-H370M:~$ cmake --version

我建议从 Ubuntu 源重新安装。

root@zeus-H370M:/home/zeus# cat /etc/os-release |grep PRETTY
PRETTY_NAME="Ubuntu 20.04.2 LTS"
