nvm should allow installation of v8-canary

[gsathya]

Link: https://nodejs.org/download/v8-canary/ has the bleeding edge v8

This would be tremendously useful for testing

[ljharb]

https://nodejs.org/download/v8-canary/index.tab is empty - and that was intentional.

See nodejs/node#13589 and nodejs/build#626 (comment).

Regardless, supporting v8 canaries would absolutely have to wait until node rc's and nightlies were supported, since those are far more important to nvm users.

[gsathya]

Alright, sound good. Since it looks like you're not opposed to this idea, can this issue be left open to track this feature request?

[ljharb]

Sure - but the index.tab would have to be populated for nvm to be able to install anything.

[targos]

The index.tab is now populated. You can install the latest canary with NVM_NODEJS_ORG_MIRROR=https://nodejs.org/download/v8-canary nvm install node

[ljharb]

Indeed; however, just like every method of using the mirror to install something nvm doesn't support, please be aware that doing so probably will cause your NVM_DIR to be pretty messed up as nvm adds support for things later.

I am trying to install Node.js canary using the method listed in this discussion, and it worked for me before but since recently I get the error below. Anybody seen that?
