After installing Blue Whale, I kept reporting an error and failed to install jq. I found several posts with wrong solutions, and finally one post was correct. Record it
Install jq under Linux
yum list| grep jq
1
If so, install jq directly
yum -y install jq
1
Enter directly on the command line: jq, then press Enter, and the following information shows that the installation is complete
jq
1
If not, use the following command
yum -y install epel-release
and then use
yum -y install jq
