I'm checking into the following things but wanted to get this logged beforehand:

  • Remove all versions of OCaml and test
  • Reinstall 4.04.0 to see if the issue persists
  • If so, Reinstall 4.02.3 to see if the issue is resolved again by switching to that version.

Edit: Adding version numbers:

  • Mac OS X 10.11.6
  • npm 3.10.10
  • node v7.3.0
  • opam 1.2.2

Removing OCaml and related tools from the system seems to allow npm install to work without issue:

==> Caveats
OPAM uses ~/.opam by default for its package database, so you need to
initialize it first by running (as a normal user):

$  opam init

Run the following to initialize your environment variables:

$  eval `opam config env`

To export the needed variables every time, add them to your dotfiles.
  * On Bash, add them to `~/.bash_profile`.
  * On Zsh, add them to `~/.zprofile` or `~/.zshrc` instead.

Documentation and tutorials are available at https://opam.ocaml.org, or
via "man opam" and "opam --help".

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

zsh completion has been installed to:
  /usr/local/share/zsh/site-functions

Done.

In normal operation, OPAM only alters files within ~/.opam.

During this initialisation, you can allow OPAM to add information to two
other files for best results. You can also make these additions manually
if you wish.

If you agree, OPAM will modify:

  - ~/.zshrc (or a file you specify) to set the right environment
    variables and to load the auto-completion scripts for your shell (zsh)
    on startup. Specifically, it checks for and appends the following line:

    . /Users/shane.logsdon/.opam/opam-init/init.zsh > /dev/null 2> /dev/null || true


  - ~/.ocamlinit to ensure that non-system installations of `ocamlfind`
    (i.e. those installed by OPAM) will work correctly when running the
    OCaml toplevel. It does this by adding $OCAML_TOPLEVEL_PATH to the list
    of include directories.

If you choose to not configure your system now, you can either configure
OPAM manually (instructions will be displayed) or launch the automatic setup
later by running:

   opam config setup -a


Do you want OPAM to modify ~/.zshrc and ~/.ocamlinit?
(default is 'no', use 'f' to name a file other than ~/.zshrc)
    [N/y/f] y

User configuration:
  ~/.ocamlinit is already up-to-date.
  ~/.zshrc is already configured for another OPAM root.
Global configuration:
  Updating ~/.opam/opam-init/init.sh
  Updating ~/.opam/opam-init/init.zsh
  Updating ~/.opam/opam-init/init.csh
  Updating ~/.opam/opam-init/init.fish
# To setup the new switch in the current shell, you need to run:
eval `opam config env`
$ eval `opam config env`
$ cd ..
$ rm -rf HelloReason
$ git clone https://github.com/reasonml/ReasonProject HelloReason
$ cd HelloReason
$ npm install

Using opam switch 4.02.3 also corrects the issue.

Funny enough, installing 4.04.0 through Opam (with opam switch 4.04.0) works, so the issue seems to be caused by system installed OCaml 4.04.0.

Great repro documentation. esy and we're looking at making esy the standard way of building packages. But what can we do in the mean time to prevent this from happening (a quicker fix?)

I would say that updating the README would be a good start, letting users know to opam switch to a non-system version if they experience issues. Thoughts?

Updated the docs, and we are working on a legit fix to this issue. Thank you for reporting.

+1 Same issue here.

Very close to getting big fix that prevents any global environment from even being perceived by the package install.
