Bug: Post-install script fails in VS Code Dev Container, subpath exports not created #1726
Description
Steps to reproduce
Environment:
OS: Standard VS Code Dev Container (Debian base)
Node.js version: 20.x
firebase-functions version: 5.0.1 and latest
Related issues
[REQUIRED] Version info
node:
v20.19.2
firebase-functions:
firebase-functions version: 5.0.1 and latest
firebase-tools:
firebase-admin:
[REQUIRED] Test case
When running npm install or yarn on the firebase-functions package (v5.x or latest) inside a standard VS Code Dev Container, the installation completes but the necessary proxy files for subpath imports (e.g., auth.d.ts, https.d.ts) are not created in the package's root. This leads to compile-time errors (TS2307: Cannot find module 'firebase-functions/auth') and runtime errors (ERR_PACKAGE_PATH_NOT_EXPORTED).
[REQUIRED] Steps to reproduce
Create a new project in a VS Code Dev Container using the official "Node.js & TypeScript" definition (using Node 20).
Create a functions directory.
Inside functions, create a package.json with the following content:
JSON
{
"name": "functions",
"main": "lib/index.js",
"engines": { "node": "20" },
"dependencies": {
"firebase-admin": "latest",
"firebase-functions": "latest"
},
"devDependencies": {
"typescript": "latest"
}
}
Run npm install (or yarn).
Run ls -l node_modules/firebase-functions/auth.d.ts.
[REQUIRED] Expected behavior
The ls command should show the file auth.d.ts.
[REQUIRED] Actual behavior
The ls command fails with No such file or directory
