正在安装`qdap` -无法安装

Question

我正在尝试安装qdap，但总是遇到错误。

我尝试过以下几种方法：

方法1：

> install.packages("qdap")
Installing package into ‘C:/Users/USER/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)
trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.6/qdap_2.3.2.zip'
Content type 'application/zip' length 3636513 bytes (3.5 MB)
downloaded 3.5 MB

package ‘qdap’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\USER\AppData\Local\Temp\Rtmp4eaFAF\downloaded_packages

所以我认为它安装成功了，然后我运行以下命令：

> library(qdap)
Error: package or namespace load failed for ‘qdap’:
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: fun(libname, pkgname)
  error: JAVA_HOME cannot be determined from the Registry

方法二：

从GitHub下载软件包并手动安装。

install.packages("C:/Users/MYUSER/Downloads/qdap-master.zip",repos=NULL)

使用devtools：

   > devtools::install_github("trinker/qdap")
Downloading GitHub repo trinker/qdap@master
These packages have more recent versions available.
Which would you like to update?

1: All                          
2: CRAN packages only           
3: None                         
4: tidyr (0.8.3 -> 1.0.0) [CRAN]
5: sys   (3.2   -> 3.3  ) [CRAN]

Enter one or more numbers, or an empty line to skip updates:
1
tidyr (0.8.3 -> 1.0.0) [CRAN]
sys   (3.2   -> 3.3  ) [CRAN]

Warning message:

Answer 1

正如PavoDive提到的，安装jre。请查看Oracle的网站以获取最新版本。安装完成后，运行以下代码片段

Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\<jre version>') # if you are using 64-bit R
Sys.setenv(JAVA_HOME='C:\\Program Files (x86)\\Java\\<jre version>') # if you are using 32-bit R

现在，您尝试加载的包应该可以正常工作。
