Try to run and build the new version 2.24.0.
The build process should download the new coca and decompress and unzip it.
The packages "decompress" and "https-proxy-agent" are missing.

It works if you do
yarn add decompress
yarn add https-proxy-agent
Try to install the new version.
Also these should be dependencies not devDependencies: (required in scripts/download-realm.js)
@arnebr @shenjunru I haven't been able to reproduce it from a fresh project (see the attached screenshot):
react-native init Test
cd Test
yarn add realm
react-native link realm
react-native run-ios

Moreover, first building a project with v2.23.0 and then upgrade to v2.24.0 also works fine.
When looking at node_modules/realm/node_modules, I see both decompress and http-proxy-agent.
Btw, I am using node v10.13.0 and yarn v1.13.0.
Indeed in a clean space it works fine, don´t know what happend here then. Sry for bothering.
@kneth, @arnebr Could you try yarn add [email protected]
NPM and Yarn do not install "devDependencies" of "dependencies"
@shenjunru As I outlined, I did try with yarn.
@kneth
Could you check listed packages exist in the project node_modules, not out of project.
Here, It is not work for [email protected] and [email protected] with [email protected] and fresh react-native project.
Thanks.
@kneth + @shenjunru
I'm having the same issue w/ npm 6.7.0, upgrading from [email protected] in an existing project.
I too got the error:

We currently don't support node.js v11. Please try again using node.js v10 or v8.
@HolySamosa Upgrading to v2.24.0 brings many new things so you might have to clean your workspace. Did you clean your workspace before building?
Found issue.
In v2.24.0, The Xcode project will run [ ! -d node_modules/fs-extra ] && npm install --no-save
Which install those modules locally inside node_modules/realm.
Also install node via nvm (same as previous versions).
I think those are not good behaviors.
realm-js.node.realm-js should has node support already.I also wrote a shell script download-realm.sh to replace download-realm.js
It provides same behavior as download-realm.js.

@shenjunru I have tried with the exact same versions as you, and the modules are installed.

I can confirm that I get this on version 2.24.0 but I don't get this when I change my package.json to version 2.23.0.
@shenjunru It's a good shell script. The reason we wrote it in JS originally was that we also need it on Windows.
The shell script within Xcode is using a particular version of node. The issue here is that if you have multiple versions of node installed, Xcode will pick the default version. Xcode is spawning a new login shell, and therefore it doesn't inherit the settings from any shell.
I'm happy to report that I'm no longer seeing this issue w/ v2.25.0. :-)
@kneth @shenjunru
I don't have this bug on my machine, but one of my workmate had this issue when compiling our project with realm-js 2.25.0.
He had to add these modules to our package.json.
"command-line-args": "^5.1.1",
"decompress": "^4.2.0",
@StevenMasini We moved those dependencies in v2.26.0 so if you upgrade, it should have been solved.
I added a issue related to this
hey guys, you just need to react-native run-ios after react-native link realm and then to Build on Xcode
