Apparently, new versions of yarn use the HOME environment variable to
figure out where to access their configuration, and sudo apparently
doesn't clear that variable, so install-node was being run with HOME
set to something under /home/vagrant (e.g.).
Fix this by just setting that environment variable correctly.
This replaces 250a036ff8, which
misdiagnosed the issue.
It appears that some change in yarn's versioning system means that
installing yarn itself ends up chowning its config directory
incorrectly to be owned by root, preventing `yarn install` from
working later.
node -> v8.9.4
yarn -> 1.5.1
nvm -> 0.33.8
Also updates a test in timerender.js which depends on time
provided by node which is now changed in newer release.
Some changes have been made in circeci script, we just create ~/.config
directory and chown it to circleci user so installing new version of yarn
does not cause any ci failure on circleci during provision.
This replaces nvm in npm-wrapper by harcoding the path the way we do
with node. The main benefit is that this saves a few hundred
milliseconds every time we invoke npm.
This fixes a significant performance issue with LaTeX rendering (and
other things that invoked node) where starting up node took a few
hundred milliseconds due to nvm initialization.
Tweaked by tabbott to avoid copying the node binary itself, instead
using a tiny wrapper script.
This is important primarily because it's possible a future version of
node will expect to find libraries/dependencies/etc. installed via NVM
at some path related to the path of the node binary itself, and that's
more guaranteed with this new model.
Fixes#4618.
