Question

我最近在个人计算机（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。

R和R Studio都无法安装任何这些软件包。每次我尝试安装软件包时，都会收到我在此帖子底部包含的警告集。

我使用了install.packages命令以及内置的软件包安装工具。我尝试了几种不同的镜子。

我曾尝试过公立大学的互联网资源，我自己的私人互联网资源和电话系绳。我试图通过VPN连接。我已将R Studio添加到我的Windows防火墙例外列表中，并且还完全禁用了Windows防火墙。我没有运行其他防火墙。

我在全局选项的“包”选项卡中切换了各种连接选项。

我可以在浏览器中访问这些网址。

以下是R Studio的警告：

R和R Studio中的软件包安装上有几个stackexchange帖子，但是我无法找到任何能够解决我特定情况的帖子。提前感谢知道正在发生什么的人

Answer 1

之前发生在我身上。尝试明确指定位置：

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

Answer 2

运行此命令：

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

之后尝试install.packages;它应该工作。在我的系统上测试。

Answer 3

使用带有参数install.packages()的{{1}}函数时，您确实可以指定位置，但您也可以选择每次下载软件包时使用的最喜欢的存储库。

repos=

您可以在CRAN website上看到所有可用镜像的列表。 Juste将最近的CRAN存储库的地址复制/粘贴给您。

您应该可以在此步骤后重试options(repos="my_favorite_CRAN_mirror")

Answer 4

您应该尝试以下代码：

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

它将帮助您安装错误的软件包：

软件包不适用于该版本

Answer 5

I was having a similar error while trying to install the packages dplyr, tidyr packages. I solved the issue by checking my R.version and downloading a new version of base R. (3.3.3)

Answer 6

尝试一下...

工具->全局选项->程序包

将“主CRAN存储库”更改为htpps位置

此方法解决了我的问题

Answer 7

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

Answer 8

我想补充一点，我遇到了这个问题，但修复不是在 R 中，而是在我们的系统中。我们的 IT 人员说：由于某种未知原因，DNS 解析器服务无法解析主机名。我已经重新启动了 resolvd 服务。服务器现在可以解析主机名。

他那边的错误是：名称解析暂时失败

R - 无法访问包安装的URL
