Let’s say you have a project with the following top level dependencies:
xlrd money babel pyinstaller jinja2 pywin32
After installing them you have the following packages:
altgraph==0.16.1 Babel==2.7.0 beautifulsoup4==4.7.1 et-xmlfile==1.0.1 future==0.17.1 jdcal==1.4.1 Jinja2==2.10.1 macholib==1.11 MarkupSafe==1.1.1 money==1.3.0 pefile==2019.4.18 pipdeptree==0.13.2 psutil==5.6.3 PyInstaller==3.4 pytz==2019.1 pywin32==224 pywin32-ctypes==0.2.0 soupsieve==1.9.2 xlrd==1.2.0
