将 qdap package 安装到 R 时出现问题

Question

我想安装“qdap”package 来运行文本挖掘项目。 我尝试以多种不同方式安装 package：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。 它似乎与 rJava package 有关。 我尝试安装 rJava，但没有成功。

我更像是数据分析师而不是开发人员，所以我没有太多开发经验（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”package。 你能帮我用简单的方式弄清楚吗？

这是我安装 package 后的错误消息：

Answer 1

也许关键在以下

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

你确定你已经安装了 JVM 吗？ 如果是，正确的？ 因为它似乎找不到它。

您可以从这里下载 JVM。

我希望这有帮助！
