Uso com typescript

[Breno Silva]

Olá,

Estou tentando usar este módulo no typescript 3.5.3. Quando chamo a função o seguinte erro aparece:

ERROR in ./node_modules/httpreq/lib/httpreq.js

Alguém já teve o mesmo problema? Desculpem se for uma pergunta besta, mas nada do que ja tentei resolveu. Obrigado desde já
