在R中安装qdap包时出现问题

Question

我想安装"qdap“包来运行文本挖掘项目。我试着用很多不同的方式安装这个包: 1. intsall.packages("qdap") 2.在本地下载文件然后安装3.使用devtools

library(devtools)
install_github("trinker/qdapDictionaries")
install_github("trinker/qdapRegex")
install_github("trinker/qdapTools")
install_github("trinker/qdap")

我总是有同样的问题。这似乎与rJava包有关。我试着安装rJava，但是没有成功。

与其说我是一名开发人员，不如说我是一名数据分析师，因此我没有太多的开发经验(使用终端命令或在我的mac上修复java )。

我真的很想使用这个"qdap“包。你能帮我想个简单的办法吗？

以下是我安装软件包后的错误消息：

Answer 1

也许关键在于以下几点：

Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.

和

Warning in system("/usr/libexec/java_home", intern = TRUE) :
  running command '/usr/libexec/java_home' had status 1

您确定已安装JVM吗？如果是，正确的是哪一个？因为它似乎找不到它。

您可以从here下载JVM。

我希望这能帮到你!
