iOS: Custom step download_realm.js fails -> Build error "realm/util/assert.hpp" not found

Goals

Just installing/building realm for use in a React Native iOS app.

Expected Results

As a pre-build step, the RealmJS target executes node ../scripts/download-realm.js ios --sync, which should populate the vendor directory with some code and build dependencies.

Actual Results

The script fails, apparently because the wrong version of lzma-native is being run/built:

lzma-native is present (v3.0.1) but doesn’t contain the particular binding node wants:

If I run the script manually (outside xcode) it succeeds:

node ../scripts/download-realm.js ios --sync
Extracting realm-sync-cocoa-2.0.2.tar.xz => <myproject>/node_modules/realm/vendor/realm-ios

(../vendor/ream-ios is now populated) However the build still fails unless I also remove the pre-build step from xcode, because a failed execution appears to wipe the realm-ios directory.

Whenever yarn reinstalls realm, I need to repeat this process. I’ve tried totally cleaning everything out - node_modules, yarn cache clean, Clean build in xcode, removing Derived data, to no avail. For some reason I always end up with a mismatched lzma-native build.

Steps to Reproduce

yarn add realm@2.0.0
react-native link realm
...build in xcode

Code Sample

Version of Realm and Tooling

• Realm JS SDK Version: 2.0.0
• Node or React Native: React Native 0.49, Node 6.3.1, yarn 0.27.5
• Client OS & Version: macOS Sierra building for iOS 11
• Which debugger for React Native: N/A (build issue)

[pekq]

After some debugging I found Xcode uses node from /usr/local/bin/ directory.

$ node --version
v7.6.0
$ /usr/local/bin/node --version
v6.2.2

So syncing both node versions to 7.6.0 fixed the issue and the download script didn’t fail anymore.

[gino8080]

both versions on xterm e “regular term” are 7.10.1

but i keep the similar error of
