问题

解决Pycharm配置R语言环境报错RWrapper terminated, exitcode: 127 error while loading shared libraries: libR.so: site:stackoverflow.com

解决方案

1. 打开GetEnvVars.R文件

打开 C:\Users\UserName\AppData\Roaming\JetBrains\PyCharm版本号\plugins\r-plugin\R\目录下的GetEnvVars.R文件。

• 注：上面的UserName和PyCharm版本号按实际情况查找，如果没有找到，看下PyCharm的安装目录有没有...\plugins\r-plugin\R\GetEnvVars.R文件，不同版本路径可能有所区别

2.1 R版本大于3

如果R版本大于等于3，将内容替换成文件GetEnvVars.R的内容替换成：

getLDLibraryPath <- function() {

  sysinf <- Sys.info()

  if (sysinf['sysname'] == "Darwin") Sys.getenv("DYLD_FALLBACK_LIBRARY_PATH")
  else if (tolower(sysinf['sysname']) == "linux") {
    if(Sys.getenv("LDLIBRARY_PATH") == "") {
      sessinf <- sessionInfo()
      interpreter_lib_dir <- dirname(sessinf$BLAS)
      paste(interpreter_lib_dir, paste0(interpreter_lib_dir, "/R/lib"), sep = ":")
    } else {
      Sys.getenv("LDLIBRARY_PATH")
    }
  }
  else ""
}

cat(">>>RPLUGIN>>>")
cat(R.home(), R.home('share'), R.home('include'), R.home('doc'), Sys.getenv("PATH"), getLDLibraryPath(), sep = '\n')
cat("<<<RPLUGIN<<<")

2.2 R版本低于3

如果R版本低于3，将内容替换成文件GetEnvVars.R的内容替换成：

    if(Sys.getenv("LDLIBRARY_PATH") == "") {
      sessinf <- sessionInfo()
      interpreter_lib_dir <- dirname(sessinf$BLAS)
      if (R.version$major <= 3)
  	  	paste(dirname(dirname(interpreter_lib_dir)), interpreter_lib_dir, sep=':')
	  else if (R.version$major > 3)
      	paste(interpreter_lib_dir, paste0(interpreter_lib_dir, "/R/lib"), sep = ":")
	  else 
	  	""
    } else {
      Sys.getenv("LDLIBRARY_PATH")
    }
  }
  else ""
}

cat(">>>RPLUGIN>>>")
cat(R.home(), R.home('share'), R.home('include'), R.home('doc'), Sys.getenv("PATH"), getLDLibraryPath(), sep = '\n')
cat("<<<RPLUGIN<<<")

其他可能的原因

如果上面的方案没有解决，可以尝试下面的解决方案：

1. 如果是从源码编译安装的，自编译的时候未使用该--enable-R-shlib选项编译 R。(源地址)
