I tried this command

sudo pip install --target=/edx/app/edxapp/venvs/edxapp/local/lib/python2.7/site-packages/ pyotp

but I faced this error

@muneera_salah, it looks like you are trying to use a Python 3 package with Python 2.7. pyotp is not supported for Python 2.7 after v2.3.0 (ref).

Also, instead of using the --target option, you can use /edx/app/edxapp/venvs/edxapp/bin/pip to install the package in the proper virtual environment.
