R 网状 package 未找到 Python win32com 模块

Question

I'm trying to use reticulate in R to access Python's win32com (in order to read password-protected Excel documents), but am failing at the first hurdle. Although my code works fine in Python, when trying to use it in reticulate , the win32com module cannot be found.

As an example:

library(reticulate)
virtualenv_create("r-reticulate-test")
py_install(envname = "r-reticulate-test", packages = "pywin32")
win32 = import("win32com.client")

Results in:

Error in py_module_import(module, convert = convert) : 
    ModuleNotFoundError: No module named 'win32com'

Answer 1

I had the same problem and the following solved the issue:

library(reticulate)
install.packages("Rcpp")
virtualenv_create("r-reticulate-test")
py_install("pypiwin32", pip = T, envname = "r-reticulate-test")
win32 <- import("win32com.client")
