我已经在 macOS Mojava v 10.14.6 上重新安装了 R 3.6 我已经从提供的安装程序中安装了 clang 7/usr/local/clang7

我有xcode

但是我似乎可以弄清楚安装有问题

.libPaths()
[1] "/Users/annaleigh/Library/R/3.6/library"                        
[2] "/Library/Frameworks/R.framework/Versions/3.6/Resources/library"
> install.packages("devtools")
Installing package into ‘/Users/annaleigh/Library/R/3.6/library’

Content type 'application/x-gzip' length 339075 bytes (331 KB)
==================================================

The downloaded binary packages are in
    /var/folders/xr/lmkkh0p10t948k1n104z1jsh0000gn/T//Rtmpf54J79/downloaded_packages
> library(devtools)
\Loading required package: usethis

 *** caught segfault ***
address 0x2c2e0, cause 'memory not mapped'

但是 usethis 库似乎加载正常

> library(usethis)
> library(devtools)

 *** caught segfault ***
address 0x2c2e0, cause 'memory not mapped'

在这里找到答案： https ://github.com/r-lib/devtools/issues/1292

“最后查看了 .libPath() 并意识到 R 的两个实例都在查看系统库之前的用户库。因此，如果包从编译版本链接到不同的系统库（在我的情况下为 OS X Sierra 和 El Capitan ) 这可能会造成段错误。

删除用户库中的库 ~/user/Library/R/version#修复了问题（安装到不同位置）”
