Production of light (anti-)nuclei and (anti-)hypertriton within midrapidity($|y|<0.5$) and $p_T<3.0$ GeV/c in $pp$ interactions at $\sqrt{s}$ = 0.90, 2.76and 7 TeV is investigated by the dynamically constrained phase spacecoalescence model (DCPC), combined with {\footnotesize{PACIAE}} model. TheALICE data for yields, ratios, as well as transverse momentum distributions of$\overline{d}$ and $d$ are well reproduced by the model simulations, meanwhilethe three basic characters of $\rm^3{\overline{He}}$, $\rm^3{{He}}$,$\rm{{^3_{\overline \Lambda}\overline H}}$, and $\rm{^3_\Lambda H}$ are alsopredicted. Besides, we found the yields of light (anti-)nuclei produced aredependent upon their mass number $A$, namely, their yields sharply decreasewith the increasing of $A$. The strangeness population factor$s_3=\rm{({^3_{\Lambda}H}/{^3{He}})/(\Lambda/p)}$ is found to be about 0.7$\sim$ 0.8, and is comparable with the available experimental results.
