expo-cli tunnel issues on Ubuntu

[fxfactorial]

yarn add --dev exp

or

npm i --dev exp

Then use the local one in your scripts of package.json:

...
"scripts": {
   "start": "exp start"
}

exp was working on Ubuntu 16.04 with version 44.0.0

but then

[exp] There is a new version of exp available (47.4.4).
You are currently using exp 44.0.0
Run `npm install -g exp` to get the latest version

so I did.

now I get error, and a failed install:

sudo npm install exp -g

> node platform.js

/usr/bin/exp -> /usr/lib/node_modules/exp/bin/exp.js

update:

so, as per usual, its permission issues.

tunnel issue has nothing to do with exp / ngrok

and everything to do with the default global node_modules folder on Ubuntu 16.04 and how ngrok can't write to it in the postinstall.js script without sudo

version 47.4.4 works fine

I fixed for myself by following the steps from here

[gregpalaci]

Deleting node_modules and reinstalling seemed to help. I also moved to https://github.com/creationix/nvm for node incase it was a persmissions issue as stated above (I didn't get feedback from npm i if it was)

Node v9.4.0
Npm v5.6.0
Expo SDK 23
Expo CLI v44.0.0

I am also facing the same issue using mac os when installing exp with
sudo npm install exp -g.

@expo/[email protected] postinstall /usr/local/lib/node_modules/exp/node_modules/@expo/ngrok
node ./postinstall.js

I tried deleting and re installing node_modules .but didnt help.Also i tried Reinstall npm with a version manager using brew install node. But after all these , same error happens

@fithaN EACCES: permission denied. It means you have a permissions issue:

I'd say one way to get around this is to use a locally installed version of exp, like as a devDependency of your package.json.

[fithaN]

how can that be done?

[fithaN]

yes.that worked.thanks

https://docs.npmjs.com/getting-started/fixing-npm-permissions
Mac can brew install node
or use nvm or n node manager
or sudo chown -R $(whoami) ~/.npm

From what I'm seeing it was a long time ago and not necessarily caused by expo. I'm going to close this, feel free to reopen if the issue still occurs.
