A [INS-44002] The Oracle home location contains directories or files on following remote nodes error was encountered while installing to Installation Location.

ORACLE_HOME,ORACLE_HOME=/u01/oracle/app/grid/product/12.2.0 is set in the environment variable

And has repeatedly confirmed that the / u01/oracle/app/grid/product/12.2.0 directory is empty, and even deleted everything under / u01/oracle/app/grid_base, that is, ORACLE_HOME and ORACLE_BASE are empty, but still encountered this error.

Carefully check the documentation, found that the Oracle software installation should not set any oracle-related environment variables, oracle default users do not set anything to start the installation. ORACLE_BASE/ORACLE_HOME is selected and specified at installation time. Second, there is a major change in the installation of GI, which no longer has runInstaller. Instead, it is unzipped directly to ORACLE_HOME and configured by running gridSetup.sh.

Solution:

1) cancel the ORACLE_HOME setting from the environment variable

2) extract grid.zip to node 1's / u01/oracle/app/grid/product/12.2.0 directory and run gridSetup.sh

3) make sure that the same ORACLE_HOME (such as / u01/oracle/app/grid/product/12.2.0) directory on other nodes is empty and that the GI installation user has access to them.
