我想向使用并行计算的CRAN提交一个包parallel::makeCluster(parallel::detectCores()).
当我构建包时一切正常,但是当我检查包(devtools::check(document = FALSE))时它返回错误:
Running examples in ‘TESTER-Ex.R’ failed
The error most likely occurred in:

Error in .check_ncores(length(names)) : 8 simultaneous processes spawned

我在MWE包(TESTER)中重新创建了错误,它只有一个函数hello_world,我已将整个TESTER包上传到GitHub,但它应该可以从以下函数重现.
#' Prints hello world
#'
#' @return nothing
#' @export …
