R - 无法访问软件包安装的URL

Question

R - 无法访问软件包安装的URL

rpackage

7

我最近在个人电脑（windows 8）上安装了R Studio（版本0.99.892），并尝试安装以下软件包: ggplot2; dplyr; rmarkdown； tidyr。

无论是R还是R Studio都不能安装这些软件包。每次我尝试安装一个软件包，我都会收到我在本文底部包含的警告信息。

我已经使用了install.packages命令以及内置的软件包安装工具。我尝试过几个不同的镜像。

我曾经尝试公共大学的网络来源，我的私人网络来源和手机热点。我尝试通过VPN连接。我已将R Studio添加到我的Windows防火墙例外列表中，并完全禁用了Windows防火墙。我没有运行其他防火墙。

我切换了全局选项中“软件包”选项卡中的各种连接选项。

我可以在浏览器中访问这些URL。

下面是来自R Studio的警告：

有几篇关于在R和R Studio中安装软件包的StackExchange文章，但我没有找到任何能够回答我的特殊情况的文章。提前感谢任何知道情况的人。

我之前也遇到过这个问题。尝试明确指定位置：

install.packages("devtools", repos="https://cran.rstudio.com/")

你应该尝试以下代码：

install.packages("ggbiplot",dependencies = TRUE, repos = 'http://cran.rstudio.com/')

这将帮助您安装与以下错误相关的软件包：

在R终端中运行以下命令- options(repos="https://CRAN.R-project.org") 然后- use-install.packages('library')

这个答案与Awinash Singh的顶部答案有何不同？ - undefined

当使用install.packages()函数并指定参数repos=时，您可以确切地指定位置。但是，您也可以选择自己喜欢的存储库，每次下载软件包时都会使用它。

    options(repos="my_favorite_CRAN_mirror")

您可以在CRAN网站上查看所有可用镜像列表。只需复制/粘贴最接近您的CRAN存储库的地址。

完成此步骤后，您应该能够重试install.packages('ggplot2')。

我想补充一下，我遇到了这个问题，但解决方法不在R中，而是在我们的系统中。我们的IT人员说：由于某些未知原因，DNS解析器服务无法解析主机名。我重新启动了resolvd服务。服务器现在可以解析主机名。

他那边出现的错误是：名称解析临时失败。

我在安装 dplyr 和 tidyr 包时遇到了类似的错误。通过检查我的 R.version 并下载新版本的基础 R（3.3.3），我解决了这个问题。

尝试这个...

工具-->全局选项-->包

将“主要CRAN存储库”更改为htpps位置

这种方法解决了我的问题

运行这个命令：

options(repos="https://CRAN.R-project.org")

之后尝试安装install.packages；应该会起作用。已在我的系统上测试。
