Yarn Error “There appears to be trouble with your network connection”

Paling ga enak itu kalo sebelumnya ga ada apa2, eh ada paket baru update, terus pas diinstal jadinya eror. Erornya aneh, katanya gara2 network connection padahal instal yg lain oke2 aja. Seperti ini nih errornya:

yarn install v1.3.2
info No lockfile found.
[1/4] Resolving packages…

info There appears to be trouble with your network connection. Retrying…
error An unexpected error occurred: “https://registry.yarnpkg.com/rxjs/-/rxjs-5.5.6.tgz: ESOCKETTIMEDOUT”

Gara2 itu jadinya paket ga bisa keinstal. Ga bisa ngoding. Setelah diterawang, kasusnya ada di paket rxjs versi 5.5.6. Padahal kalau didonlot manual lewat browser bisa aja, meski nyangkut ketika 99%.

Googling2 ga nemu2 solusinya, akhirnya terpaksa baca yarn help, ternyata bisa atur timeout koneksi. Jadilah ditambahkan perintah:

yarn add [namapaket] — network-timeout 18000

Jadi, timeout koneksi jaringannya dijadikan 18000 ms, alias berapa menit ya? Ga paham. Haha.. ngasal soalnya :D
