Postinstall of module is executed before postinstall of sub-module - node.js

Question

Edit:
I'm asking how to install it from GitHub, not npm, that the question.
In case you want to know why: I'm working on some private projects and don't what t publish the code. This leads to the code being in a private repository, not published on npm.
Original post:
Trying to install a module from GitHub (it is in typescript, thus I need a compilation script [postinstall]). It seems to fail because one of the module dependencies is also on GitHub, and that postinstall script is not waited on by the current postinstall script.
Old GitHub issue that sounds related: https://github.com/npm/npm/issues/5001
Yes, like the issue, I also use the same dependency in the main project as the module does.

It's not a good practice to publish unbuilt packages. I recommend changing the postinstall script into a prepare script so it builds the package before publishing it.
{
"name": "newton",
"version": "1.0.1",
"description": "",
"scripts": {
"lint": "eslint '*/**/*.ts'",
"lint:fix": "eslint '*/**/*.ts' --fix",
"prepare": "tsc -d -p .",
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"devDependencies": {
"#typescript-eslint/eslint-plugin": "^4.22.0",
"#typescript-eslint/parser": "^4.22.0",
"eslint-config-prettier": "^8.3.0",
"eslint-plugin-prettier": "^3.4.0"
},
"dependencies": {
"typescript": "^4.2.4"
}
}
{
"name": "rendery",
"version": "2.0.0",
"description": "",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"lint": "eslint '*/**/*.ts'",
"lint:fix": "eslint '*/**/*.ts' --fix",
"prepare": "tsc -d -p ."
},
"keywords": [],
"devDependencies": {
"#typescript-eslint/eslint-plugin": "^4.22.0",
"#typescript-eslint/parser": "^4.22.0",
"eslint": "^7.25.0",
"eslint-config-prettier": "^8.3.0",
"eslint-plugin-prettier": "^3.4.0",
"eslint-plugin-typescript-sort-keys": "^1.6.0"
},
"dependencies": {
"newton": "github:Elias-Graf/newton#main",
"typescript": "^4.2.4"
}
}
This would fix your issue.
