Permission denied when installing go mockgen-CodePudding

I am trying to install the mockgen package on go but keep receiving a permission denied without knowing why

$ go install github.com/golang/mock/[email protected]
go install github.com/golang/mock/mockgen: copying /tmp/go-build3889221292/b001/exe/a.out: open /home/nocnoc/go/bin/mockgen: permission denied

I have tried using sudo or executing it as root but I receive this error

sudo: go: command not found

My GOROOT is /usr/local/go and GOPATH is in my home directory, GO1111MODULE is also on

Any ideas? Everything else seems to run fine, only mockgen seems to fail to install

The issue was the permissions and owners of ~/go and ~/go/bin. It was solved by using the chown command to change the owner of those two directories from root to my user

drwxr-xr-x 10 root   root       4096 Aug 11  2020  go

drwxrwxr-x 10 nocnoc nocnoc     4096 Aug 11  2020  go

The permissions and owners of ~/go/bin are the same as those for the directory above

I'm no linux expert but try running:

$ sudo su
$ go install github.com/golang/mock/[email protected]
