覆盖NPM项目的`npm install`脚本

Question

I have an NPM project, when npm install is run, I'd like to run a custom script.

I tried using this in package.json:

"scripts": {
    "ng": "ng",
    "start": "ng serve",
    "install": "./scripts/install.sh",   // <<<<
 },

but that actually just resulted in an infinite loop. The reason I am looking for this, is because there are tools that simply call npm install , so I can't control what they run. Otherwise, if I had control, I would just call ./scripts/install.sh myself instead.

Note that this is probably not the best idea, just curious if it's possible.

Note my install script looks something like this:

#!/usr/bin/env bash

export FOO="bar";
export PUPPETEER_SKIP_CHROMIUM_DOWNLOAD="true";

npm install

Use preinstall to run code before npm install . Don't try to override npm install in this fashion where you would end up with an infinite loop of calls to npm install .

You can also set environment variables using the config property of package.json . See docs for details
