ggbiplot下载失败的解决方法

今天的内容本来是运用R语言进行主成分分析（PCA），结果TM第一步就卡住了，下载ggbiplot包花费了我半个下午的时间。
以下是宝贵的经验，亲测有效。如果是下载其他的包，遇到相似的问题，这个方法应该也是适用的。

> install.packages("devtools")
> library(devtools)
> install_github("vqv/ggbiplot")

如果你用上面的代码成功下载了，算你厉害。

而我运行的结果一直是这样的：

library(devtools)
install_github("vqv/ggbiplot")
错误: Failed to install 'unknown package' from GitHub:
  schannel: failed to receive handshake, SSL/TLS connection failed

或者是这样的：

错误: (由警告转换成)程辑包'ggplot2'是用R版本3.6.3 来建造的
停止执行
ERROR: lazy loading failed for package 'ggbiplot'
* removing 'C:/Program Files/R/R-3.6.2/library/ggbiplot'
* restoring previous 'C:/Program Files/R/R-3.6.2/library/ggbiplot'
错误: Failed to install 'ggbiplot' from GitHub:

  /Local/Temp/RtmpQhQAak/file25f448948cb
  /ggbiplot_0.55.tar.gz’ had non-zero exit status

尝试了无数次依然不行。我决定去github手动下载到本地，然后再解压安装到library下。然而，结果是这样的：

"ggbiplot"不是有效的已经安装了的程序包

就在我在苦苦寻找解决方法时，Stack Overflow里的一个问题与我现在面临的问题非常相似！我尝试了下面的一个回答，没想到居然成功了！让我哭一会…
就是这个：

 install.packages("C:/Users/Administrator/AppData/Local/Temp/RtmpQhQAak/file25f448948cb/ggbiplot_0.55.tar.gz", repos = NULL, type = "source")

这里的路径就是上面提示错误的路径。复制过来就好了：

install.packages("C:/Users/Administrator/AppData/Local/Temp/RtmpQhQAak/file25f448948cb/ggbiplot_0.55.tar.gz", repos = NULL, type = "source")
