Goal: I want to install dssrip package for R 3.6.0 32-bit on Windows 10 Enterprise.

我安装了 32 位和 64 位版本的 R 3.6.0。在 RStudio (1.2.1522) 中，我将默认版本设置为 32 位，然后创建启用 packrat 的新项目。我在项目文件夹内的 .Rprofile 文件中包含了以下几行。

#### -- Packrat Autoloader (version 0.5.0) -- ####
source("packrat/init.R")
#### -- End Packrat Autoloader -- ####

dir.create("packages", recursive = TRUE, showWarnings = FALSE)
.libPaths("./packages")
message("Using library: ", .libPaths()[1])

options(dss_jre_location="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")
Sys.setenv(JAVA_HOME="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")

安装:

install.packages(c("devtools", "rJava", "plyr", "reshape2", "stringr", "tidyverse"),
                 dependencies = TRUE)
library(rJava)
devtools::install_github("eheisman/DSS-Rip",
                         args = "--no-multiarch")

Java 版本:

C:\Program Files (x86)\HEC\HEC-DSSVue\java\bin>java -version
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode)

C:\Program Files (x86)\HEC\HEC-DSSVue\java\bin>java -d64
Unrecognized option: -d64
Could not create the Java virtual machine.

我尝试使用 native R (C:\Program Files\R\R-3.6.0\bin\i386\Rgui.exe) 但它也没有帮助。

提前感谢您的指点!

最佳答案

更新 2:dssrip已更新以使用 64 位 r和 java .您将需要 HEC-DSSVue 的 64 位兼容版本(例如，v3.2.3)。

更新:我必须卸载并删除所有内容，然后从头开始才能使 dssrip 正常工作。

将以下行放入.Rprofile 文件中:

options(dss_jre_location="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")
Sys.setenv(JAVA_HOME="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")

安装所有依赖:

install.packages(c("remotes", "rJava", "data.table", "plyr", "reshape2", "stringr", "tidyverse"),
                 dependencies = TRUE)

请注意，要强制 R 仅安装 32 位版本，我必须使用 this syntax相反:

remotes::install_github("eheisman/dssrip",
                         INSTALL_opts = "--no-multiarch")

关于r - 强制 devtools::install_github 只安装 32 位版本的包？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56585706/
