Exp command not working in linux

When i want to create android build using exp build:android then terminal
give me following error:-

exp build:android

Usage : exp [-h] [-v level] [-o outfile] [infile]

-h this help
-v verbose mode (level is 1:2:3:4)
-o define the output file (stdout by default)
infile define the input file (stdin by default)

Please someone help me to solve this problem .
Thanks in advance.

Hey Kulbhushan, it seems that you have another package with a command named exp installed that isn’t the Expo exp command-line tool. Your error looks like it’s the exp command from a package named alliance.

To fix this, please try these steps:

  1. Uninstall the other exp command: sudo apt remove alliance
  2. Install our exp tool: npm install -g exp

I try these steps but it give me following error in terminal : -

Please i don’t know how to fix it please help me to solve problem .

Hey @kulbhushansingh - could you check and see if you have npm 5 installed (npm -v) and if so, try downgrading to npm 4 (npm install -g npm@4)? If you’re able to do that, it may fix your issue.

If that doesn’t work, you could try some of the steps here: https://docs.npmjs.com/getting-started/fixing-npm-permissions

Sorry, this sounds like an annoying issue. Let us know if you’re still having trouble after trying those things!
