EINVAL when installing on Docker on CircleCI

* **Version**: 2.3.6
* **Platform**: Linux (Ubuntu)

Hi,
when running `ied install` on a Docker image on CircleCI I'm getting the following error:

```
/usr/local/lib/node_modules/ied/node_modules/rxjs/Subscriber.js:227
throw err;
^

Error: EINVAL: invalid argument, chown '/root/.ied_cache/.tmp/337bc16e-a3ae-4256-8c8a-be8b2f70ebae/package.json'
at Error (native)
```

It seems it can't use the ied cache. It's probably not related to ied but I'm just leaving it here just in case some of you have faced this issue before.
