Para uma biblioteca vinculada a -lfoo , procure por libfoo.so e pacotes que a fornecem. libz.so é fornecido por zlib1g-dev .
Eu tenho o seguinte erro depois de digitar o comando:
pip install -r requirements.txt
A mensagem de erro é a seguinte:

Qual biblioteca ausente precisa ser instalada (por -lz ) no Ubuntu?
