Carla: [0.9.5] when using the command "make launch" there is an error

[sheepwxy]

hello. I want to install Carla on my computer as the instructions by the DOCS, however, after I use the command "make launch",there is an error as below:

Setup.sh: llvm-6.0-ex already installed.
Setup.sh: boost-1.69.0 already installed.
Setup.sh: rpclib-v2.2.1_c1 already installed.
Setup.sh: googletest-1.8.0-ex already installed.
fatal: Not a git repository (or any of the parent directories): .git
Util/BuildTools/Linux.mk:101: recipe for target 'setup' failed
make: * [setup] Error 128

my Ubuntu Version is 16.04 Unreal Version is 4.21.

ps: I have doubted that the error is caused by the older version in my computer. So i remove the older Carla0.9.1 and the older Unreal 4.19. However it does not work.

Hello @sheepwxy have you try after removing the old versions (Carla && Unreal) to rebuild ?
make rebuild

[sheepwxy]

thanks for your replying, but there is an new error

fatal: bad revision 'HEAD'
Util/BuildTools/Linux.mk:101: recipe for target 'setup' failed
make: * [setup] Error 128

You lost your .git folder I think.
Did you clone the repo or copy paste from somewhere ? You're first error message said you've no folder .git, and for your second message no "HEAD" (git).

Try to reclone the repo -> ./Update.sh -> export UE4_ROOT=~/UnrealEngine_4.21 -> make launch
