ggplot2 的命名空间加载失败，网格的描述失败

Question

我最近删除了几个 R 包（使用 remove.packages()），并重新安装了它们的最新版本。我尝试使用以下语法重新安装库网格：

url <- "https://cran.r-project.org/src/contrib/Archive/grid/grid_0.7-4.tar.gz"
pkgFile <- "grid_0.7-4.tar.gz"
download.file(url = url, destfile = pkgFile)
install.packages(pkgs=pkgFile, type="source", repos=NULL)
unlink(pkgFile)

我收到以下警告和错误：

Error : Invalid DESCRIPTION file

Invalid package name.
This is the name of a base package.

See section 'The DESCRIPTION file' in the 'Writing R Extensions'
manual.

ERROR: installing package DESCRIPTION failed for package ‘grid’
* removing ‘/Library/Frameworks/R.framework/Versions/3.3/Resources/library/grid’
Warning in install.packages :
  installation of package ‘/Users/lindz/RNASeqVisualization/grid_0.7-4.tar.gz’ had non-zero exit status

看来grid现在是base R的一部分了，所以我暂时移步了。然而，在重新安装包 ggplot2 时使用：

install.packages("ggplot2")

我收到了以下警告：

当我然后运行:

library(ggplot2)

我收到错误：

Error : package ‘grid’ does not have a namespace
Error: package or namespace load failed for ‘ggplot2’

我现在不确定该怎么做。我看过类似的帖子 (R error package grid does not have a namespace)，但他们的解决方案对我不起作用。我的任何库中都没有保存网格，因为我已经卸载了它（使用 remove.packages()）。

我的sessionInfo()如下：

如有任何建议，我们将不胜感激！

grid 是一条红鲱鱼，它自带 R，无需尝试重新安装（否则更新 R 本身）。

ggplot2 你应该从 CRAN 或 github 安装，而不是 R-forge。试试 CRAN 存储库。
