Anchore-cli on Dockerfile

Hi
I put the following code on dockerfile :
RUN git clone --depth=1 GitHub - anchore/anchore-cli: Simple command-line client to the Anchore Engine service &&
cd anchore-cli &&
python3 -m pip install --user --upgrade anchorecli
but it showed me the error :ERROR: failed to solve: process “/bin/sh -c git clone --depth=1 GitHub - anchore/anchore-cli: Simple command-line client to the Anchore Engine service && cd anchore-cli && python3 -m pip install --user --upgrade anchorecli” did not complete successfully: exit code: 1 , Why?
