[bubenshchykov]

thx for reporting!
looks like it's a regression of previous pr
https://github.com/bubenshchykov/ngrok/pull/85/files#diff-551007241ae61889b0f85f47aa764343R106

@gaoqiankun can you quickly spot some permission problems here?

outputStream.write(data); // temp file
fs.createWriteStream(localFile); // or here

I can add .on('error') handlers to prevent uncaught, but I'm not sure what the problem is yet

Hi,

No problem. I am working on a project right now, but I should be done with it in 3-ish hours. If you want and have not solved it by then, I can take a look and see if I can resolve it and will add a pull request if I do.

@TKOBabu
I have tried sudo npm i -g ngrok on archlinux, but i got a lot package not found error
e.g.

vagrant@archlinux:~$ sudo npm i -g ngrok

Then, i install ngrok on ubuntu by sudo npm i -g ngrok and on cygwin bynpm i -g ngrok, it works fine.

I don't think creating read/write stream will cause permission problem, and I never use archlinux before, can you give me some more time, to find what the real problem is.

[bubenshchykov]

@gaoqiankun @TKOBabu thanks for investigation!
I tried global install on mac only, with and without cached bin - both cases worked fine.
can you try to bump npm and install ngrok again npm i npm -g ?

[gaoqiankun]

@bubenshchykov
sudo npm i -g npm works successfuly, but when i run npm --version, it throw error

vagrant@archlinux:~$ sudo npm i -g npm@2

Then i tried sudo npm i -g typescript, it works fine

vagrant@archlinux:~$ sudo npm i -g typescript

Then sudo npm i -g node-sass, and i got permission error

So, it may be a bug of npm on archlinux.

[bubenshchykov]

please try sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share} as npm suggests https://docs.npmjs.com/getting-started/fixing-npm-permissions

[bubenshchykov]

@TKOBabu might be fixed in latest version, can you try?
if issue still happens, pls report in #88 - there was a discussion there

[ankibalyan]

@bubenshchykov should not modify ownership / permission for bin,share, It may get worse. I've experianced.
sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

just sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules} should work.

[toxdes]

Anyone who's going to use

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

think 100 times before. I just had to reinstall entire ubuntu cause I accidently ran

chown -R

on /usr . There's no solution if you change permissions of files that you don't even know.

[ankibalyan]

@malivp3494 I've already mentioned that above. You should have read that. 😈

[toxdes]

@ankibalyan yeah, but I read the solution somewhere else, and went with it. And now I regret it. There really needs to be other way around instead using chown -R

[ankibalyan]

way I do is,
Download node, npm binaries seperatly than put the excutable file path in env var $PATH rather than installing os dependents. It waorks way smothly and no need of sudo anymore.
