External2 C_savehistory error in reticulate::repl_python() for RStudio latest version (v.1.2.1335)

[gundalav]

I was trying to run Python Script from within RStudio latest version (v.1.2.1335).

I am following this instruction.

I begin by typing:

 > reticulate::repl_python()

But I get this error:

Error in .External2(C_savehistory, file) : No such file or directory

How can I solve this?

What happens when you try to invoke utils::savehistory() directly? What is the output of getwd()?

I get this message and error:

> utils::savehistory()
Error in .External2(C_savehistory, file) : No such file or directory
> getwd()
[1] "/home/ubuntu/storage1/my_analysis"

Then I don't have a good idea as to what's going on -- evidently R is not letting you write to the .Rhistory file in /home/ubuntu/storage1/my_analysis, but I do not know why.

I remove the .Rhistory file, now it's working. Thanks.

I found this happen when not having access to root directory. Using setwd(...) into a directory with write permission solved the issue

My issue was that I didn't have read/write permissions for that directory. Once I changed my permissions, I was good to go.

Thank you for this, agreed, using setwd('/path_to_wd/) resolved the issue in RStudio for me as well.
