Installation Issue

#1

Hi folks,

  I am facing this issue while installing expo. I am following "https://docs.expo.io/versions/v16.0.0/guides/building-standalone-apps.html" this link and have executed npm install -g exp, but unfortunately it shows :

tar.unpack unzip error /var/folders/kl/d33brmlx07l2gsr0yj5mjk_c0000gn/T/npm-2027-842d605d/registry.npmjs.org/_40expo/ngrok/-/ngrok-2.2.9.tgz

I tried uninstalling node but still the same, I have then installed yarn but it gets stuck at 424/425.

Kindly guide.

It seems like things didn’t download completely, I would try to install with yarn again. Sometimes it does seem like it gets stuck at the last value of the counter, but it does go through (in my experience)

#3

I have tried 3-4 times but it always get stuck at 424/425

#4

Run with verbose to see what its stuck on

I’m not sure how to resolve this but it looks like the issue could be unrelated to Expo. Several other people have encountered similar errors with other projects – search for “npm Z_BUF_ERROR” for example. That might lead you to a solution.
