Nvm: can't install nvm on centos 6

[hUangDDD]

that is the error

=> Downloading nvm from git to '/root/.nvm'
=> Initialized empty Git repository in /root/.nvm/.git/
error: while accessing https://github.com/creationix/nvm.git/info/refs

fatal: HTTP request failed
Failed to clone nvm repo. Please report this!

I'd recommend not using root with nvm; but either way, this suggests you might have SSL issues.

What happens if you curl --verbose https://github.com?

[hUangDDD]

you are right, ssl component was incorrect on that machine

I have the same issue right now, but found the following digging in here and there...:
Centos 6 comes with the GIT version 1.7.1 by default, and GIT option "-c" wasn't supported yet. So the only way to pass thru this issue would be upgrading git. :(

[ljharb]

Indeed; the readme states 1.7.10 is required. Upgrading such an ancient version of git, however, should be desirable anyways.

Sure thing, just finished upgrading git to v.2.16 and after that, NVM installation script ran smoothly👌
