Error detected while processing VimEnter

[DarkEye123]

I hit this error:

Error detected while processing VimEnter Auto commands for "*":
E492: Not an editor command:  NERDTree | endif

Not sure what is wrong to speak the truth. I was doing all steps as described.
When I load some .go src file it is visible that some plugins are loaded and working. But some are not.

Also GoInstallBinaries is not among editor commands. Not sure if it helps
