for version in 2.7.15 3.6.5 pypy-5.7.1 pypy3.5-6.0.0 ; do \ pyenv install -s $version; \ done

I have both python 2.7 and 3.6 but I can't run make dev without seeing this error:

for version in 2.7.15 3.6.5 pypy-5.7.1 pypy3.5-6.0.0 ; do \
        pyenv install -s $version; \
done

Does anyone know the fix for this or why it is happening? I did pyenv install -s $version; nut it just throws out another error :

[root@typus python-twitter]# make dev
for version in 2.7.15 3.6.5 pypy-5.7.1 pypy3.5-6.0.0 ; do \
        pyenv install -s $version; \
done
