Invalid handle using sys.subprocess

[aparks123]

I have latest preview of RStudio 1.2.1578 and in an RMarkdown document I am running python subprocess (gradle.bat is in path). This command works in python cmd env but not in rstudio.

import sys,subprocess
print("Python Version:")
print(sys.version)
print("Gradle Version:")
sp = subprocess.run(['gradle.bat','-v'],universal_newlines=True,stdout=subprocess.PIPE)

get an invalid handle error:

Python Version:
3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)]
Gradle Version:
OSError: [WinError 6] The handle is invalid

Detailed traceback:

Perhaps related to: #518

I wonder if you can run the subprocesses with stdin read explicitly from an empty file or something similar.

I could probably pipe output to an actual temp file somewhere and read that. Kind of hacky though.

--UPDATE
That actually doesn't work either, same invalid handle error:

f=open("temp.out","w+")
print("Gradle Version:")
sp = subprocess.run(['gradle.bat','-v'],universal_newlines=True,stdout=f,shell=True)

@aparks123

I´m getting the same error when running

import subprocess

subprocess.run(" ".join([r'"C:/Program Files (x86)/Renewable NRG Systems/SymPRO Desktop/SymPRODesktop.exe"']), stdout=subprocess.PIPE)

Did you solve it?

some help?
