import("pandas") error - version `GLIBCXX_3.4.21' not found

Start by reproducing the exact conda setup and import("pandas") call on CentOS 7. Read the rpytools/loader.py entry point shown in the traceback and inspect the reticulate paths involved in conda_create(), conda_install(), and use_condaenv(). Done means the reproducible example imports pandas without the GLIBCXX_3.4.21 error.

Reproducible example:

library(reticulate)
path_to_conda='~/bin/Software/miniconda3/bin/conda'
conda_create("test", conda=path_to_conda)
conda_install("test", c("pandas", "matplotlib"), conda=path_to_conda)

use_condaenv("test", required=TRUE, conda = path_to_conda)
import("pandas")

Error Message:
