Błąd odmowy uprawnień podczas próby instalacji wiązu w sudo na ubuntu

Question

Próbuję zainstalować elm na moim komputerze (Ubuntu 16.04.2 LTS).

Uruchamianie $ npm install -g elm zgodnie z instrukcjami pod tym linkiem, pojawia się błąd uprawnień. Więc próbuję ponownie z sudo, tj. $ sudo npm install -g elm.

Daje to kolejny błąd uprawnień, mianowicie

$ sudo npm install -g elm

Jak mogę przystąpić do instalacji Elm?

Answer 1

Idealnie, uprawnienia na /usr/local/lib/node_modules/ są takie, że nie trzeba uprawnień root, aby zainstalować coś tam.

Jeśli nie jest to możliwe, trzeba powiedzieć, że jest npm nie powinna spaść swoje uprawnienia roota (które jest bezpieczne-guard, aby zapobiec zbójeckie skrypty instalacyjne z systemem jako root):

$ sudo npm install --unsafe-perm -g elm
