Lock file issue after installing `pkgdepends` within a Docker container

[Faizal-Eeman]

I'm trying to install pkgdepends in a docker container and the installation seems to be fine. However, when I try to use the functions interactively after the image has been built, I get the following lock file does not exist error.

Example:

> library(pkgdepends);
> new_pkg_deps("dplyr");
Error in lock(lockfile) : 
  Directory of lock file does not exist: '//.cache/R/pkgcache/pkg'
In addition: Warning messages:
1: In normalizePath(cdir) :
  path[1]="//.cache/R/pkgcache": No such file or directory
2: In normalizePath(cdir) :
  path[1]="//.cache/R/pkgcache": No such file or directory
3: In normalizePath(dn) :
  path[1]="//.cache/R/pkgcache/pkg": No such file or directory

Is there anything to be configured in the Dockerfile before installing pkgdepends?

Let me know if you need any specific information to help me out with this.

Can you show a Dockerfile that fails?

Dockerfile is below. The build succeeds but when I run the image interactively and test out the package, I see the error shown above.

    apt-get install -y --no-install-recommends \

Oh, I was able to fix this!

This is to do with how I run the image.

docker run -it --rm -u $(id -u):$(id -g) pkgdepends:dev bash

starts the container without a user name and the lock file location wasn't accessible.

So what worked now is that once I'm in the container, I exported a temp path to HOME

I have no name!@xxx:/$ export HOME=/tmp

I have no name!@xxx:/$ R

> library(pkgdepends);
> new_pkg_deps("dplyr");
<pkg_dependencies>
+ refs:
  - dplyr
(use `$resolve()` to resolve dependencies)
(use `$solve()` to solve dependencies)

I appreciate your response on this. Thanks so much! Faizal
