Problem

vue-cli-service serve src/nginxconfig/mount.js, called from npm run dev, tries to write to /.config/..., and from there on everything breaks.

$ git clone https://github.com/digitalocean/nginxconfig.io.git
$ cd nginxconfig.io/
$ npm ci
...
$ npm run dev

Note that I'm not requesting an NPM global install or anything like that.

What I have tried

I've tried to check if there's some missing path configuration (i.e. some DIR='' variable would explain the attempted acccess to $DIR/.config/... resolving to /.config/...). I couldn't find it.

We don't do anything custom with postcss, this sounds like an upstream issue with Vue's CLI service, or something specific to your local installation/config of Node and your system.

[mralusw]

Thanks for the prompt response. I've bisected it to 895d448. That's where the EACCESS error starts to appear. Before that commit, it runs without errors.

I've also tried nodejs=18.12.1-deb-1nodesource1 as recommended by nodejs.org. Same error, also starting at 895d448 (with node 18 I also get an EBADENGINE Unsupported engine during npm install, which seemingly doesn't matter).

I had the similar error in a project and could fix either by disable the automatic configuration of the postcss loader in the webpack config file (in my case the vue.config.js):

module.exports = { ... css: { ... loaderOptions: { postcss: { postcssOptions: { config: false } } } }

or by creating a simple postcss configuraton file in the project root directory postcss.config.js :

module.exports = {};

Nice one @jonaswjs :^)

When your system is Linux, and your code is on a disk with an NTFS partition, you may encounter this issue, which can be resolved using the method provided by @jonaswjs 。

Possibly, adding support for ntfs-3g could also solve the problem?
