error: [ENOENT] Failed to make directory '//.cache/pins'

Issue

Trying to load the pins package via library("pins") results in the error:

Error: package or namespace load failed for ‘pins’:
 .onLoad failed in loadNamespace() for 'pins', details:
  call: NULL
  error: [ENOENT] Failed to make directory '//.cache/pins': no such file or directory
Execution halted

The package is assuming that .cache/pins exists, but it does not in the Docker container from which the code is run. I'm not sure what's going on with the // in '//.cache/pins'.

I added to mkdir -p /.cache/pins to my RUN command in my docker file, which just changed the error:

Error: package or namespace load failed for ‘pins’:
 .onLoad failed in loadNamespace() for 'pins', details:
  call: NULL
  error: [EACCES] Failed to make directory '//.cache/pins/local': permission denied

...so I had to open up permissions for /.cache/.

Maybe a vignette on using pins with Docker (& Rocker) could be helpful.

Thanks for reporting your problems @nick-youngblut!

I was trying to reproduce the problem with my typical Docker workflow. First I did this to generate an renv.lock:

renv::snapshot(
  project = NULL,
  lockfile = "renv.lock",
  packages = "pins",
  prompt = FALSE
)

Then I build this Dockerfile:

FROM rocker/r-ver:4.2.1
ENV RENV_CONFIG_REPOS_OVERRIDE https://packagemanager.rstudio.com/cran/latest

RUN apt-get update -qq && apt-get install -y --no-install-recommends \
  libcurl4-openssl-dev \
  libssl-dev \
  make \
  && apt-get clean

COPY renv.lock renv.lock
RUN Rscript -e "install.packages('renv')"
RUN Rscript -e "renv::restore()"
RUN Rscript -e "library(pins)"

That ran without error and then I could do docker run --rm -ti pins-example and run pins in the container.

I also tried this Dockerfile and it also worked fine for me:

FROM rocker/r-ver:4.2.1
ENV RENV_CONFIG_REPOS_OVERRIDE https://packagemanager.rstudio.com/cran/latest

RUN install2.r pins

If you are able to create a minimal example that shows the problem you were experiencing with pins and Docker, we would be happy to check it out!

You will probably need to use VS Code with a devcontainer (as shown above) to reproduce the issue.
