When installing a git dependency using the Docker image node:10-alpine via npm ci, attempts to npm prune --production result in an error like:

npm ERR! code 128
npm ERR! Command failed: git clone --mirror -q https://github.com/nodecraft/ampify.git /root/.npm/_cacache/tmp/git-clone-6573274f/.git
npm ERR! fatal: could not create leading directories of '/root/.npm/_cacache/tmp/git-clone-6573274f/.git'

To help replicate the issue, this repo contains a package.json and package-lock.json. I then have a Dockerfile which when building, illustrates the issue.

To build the image, simply run: docker build -t test .

You can tweak the npm version to see it working/failing on different version on line 3 of the Dockerfile.

For more information, see the reported issue at: npm/cli#514
