Error in checkForRemoteErrors(lapply(cl, recvResult))

Hello,

When I tried to use SAVER, it returned some error message,

Running SAVER with 10 worker(s)
Calculating predictions for 23131 genes using 17490 genes and 12346 cells...
Start time: 2021-06-09 06:07:12
Estimating finish time...
Error in checkForRemoteErrors(lapply(cl, recvResult)) :
10 nodes produced errors; first error: object '.doSnowGlobals' not found

Is there anyway to resolve this ?
Here is my sessionInfo()

I solved this problem by installing the SAVER, doParallel and doSNOW packages into the root directory.
I think it is not a safe solution way.

Is there any other way to solve this problem ?
