Error URI malformed após a execução do npm install

Segui os seguintes procedimentos:

1. Baixei o zip do projeto e descompactei no meus documentos numa pasta chamada C:\Users[nome_usuario]\Documents\cursos\alura\angular\alurapic

2. Baixei a última versão do node.js >> node-v8.5.0-x64.msi e instalei no caminho padrão do meu Windows 10 64

3. Executei o npm install de dentro do projeto pela linha de cmd

4. O resultado que aparece é um erro de URI mal formatado

Obs.: Estou usando meu micro que está numa rede corporativa, entretanto, sou administrador da máquina.

Preciso de orientação como proceder para resolver este problema.
