error in run_idf and run function about eplusr HOT 4 CLOSED

That's the designed behavior. read_idf() will fail if eplusr could not find the corresponding version of IDD file and run_idf() will fail if corresponding version of EnergyPlus. But the error messages you got were wired. It should be something like below:

read_idf("schedule.idf")
#> Error : Idd v8.5.0 has not been parsed before. Try to locate `Energy+.idd` in EnergyPlus v8.5.0 installation folder `C:/EnergyPlusV8-5-0`.
#> Failed to locate `Energy+.idd` because EnergyPlus v8.5.0 is not available. 

run_idf(model = "schedule.idf", weather = "test.epw")
#> Error : Cannot locate EnergyPlus v8.5.0 at default installation path `C:/EnergyPlusV8-5-0`. Please specify explicitly the path of EnergyPlus installation.

You can list all available EnergyPlus and IDD using avail_eplus() and avail_idd().

eplusr tries to find all available EnergyPlus installed at default locations (for Windows C:\EnergyPlusVX-Y-Z) . As your EnergyPlus was not installed at the default location, you have to add the path using use_eplus() before you parse or run any model of that version.

Thanks for the reply! In fact, I have use specify the corresponding version of IDD by use_eplus(eplus = 'D:/EnergyPlusV8-5-0' ), the results seems indicate the IDD file has been parsed:

> library(eplusr)
> use_eplus(eplus = 'D:/EnergyPlusV8-5-0')
EnergyPlus v8.5.0 located at `D:/EnergyPlusV8-5-0` has been added.
> idd <- use_idd(8.5)
Idd v8.5.0 has not been parsed before. Try to locate `Energy+.idd` in EnergyPlus v8.5.0 installation folder `C:/EnergyPlusV8-5-0`.
IDD file found: `D:\EnergyPlusV8-5-0\Energy+.idd`.
Start parsing...
  Parsing IDD (Complete) [====================================================] 100% in  3s

The avail_eplus() and avail_idd() also show the V8-5 is available:

> avail_eplus()
[1] "8.5.0"
> avail_idd()
[1] "8.5.0"

I try to install the EPlus in the default path, but it shows the same error messages. Is there something broken in the processx package in my R environment?

I install R 3.5.0 and the code works. It seems something is broken in my R 3.5.1 about callr or processx.

Thanks for your help.

The codes also works after I reinstall the ps processx and callr packages. Therefore, I guess the problem occurs because one of the three package is broken, it is not caused by eplusr itself.

Thanks for the info! Good to know so.
