我尝试按照此处的说明进行操作：https://github.com/Rdatatable/data.table/wiki/Installation
还有这里的建议：installing data.table on macOS
但到目前为止一直被卡住。
我在 Apple M1 芯片上运行 Big Sur 11.2。
我的sessionInfo()看起来像这样
R version 4.0.3 (2020-10-10)
Platform: x86_64-apple-darwin17.0 (64-bit)
Running under: macOS Big Sur 10.16
Matrix products: default
LAPACK: /Library/Frameworks/R.framework/Versions/4.0/Resources/lib/libRlapack.dylib
locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8
attached base packages:
[1] stats graphics grDevices utils datasets methods base
loaded via a namespace (and not attached):
[1] compiler_4.0.3 tools_4.0.3
（所以我认为这是在 Rosetta 下运行的）。
如果我 install.packages("data.table")，它可以工作，但我收到通知说不支持 OpenMP 并且 data.table 是单线程的。
所以我尝试了 install.packages("data.table", type = "source") 并得到了这个：
trying URL 'https://cran.rstudio.com/src/contrib/data.table_1.13.6.tar.gz'
Content type 'application/x-gzip' length 5303120 bytes (5.1 MB)

* installing *source* package ‘data.table’ ...
** package ‘data.table’ successfully unpacked and MD5 sums checked
** using staged installation
*** pkg-config is not installed.
*** Compilation will now be attempted and if it works you can ignore this message. In
*** particular, this should be the case on Mac where zlib is built in.
*** However, if compilation fails, try 'locate zlib.h zconf.h' and ensure the zlib
*** development library is installed :
*** deb: zlib1g-dev (Debian, Ubuntu, ...)
*** rpm: zlib-devel (Fedora, EPEL, ...)
*** There is a zlib in brew for OSX but the built in zlib should work.
*** Note that zlib is required to compile R itself so you may find the advice in the R-admin
*** guide helpful regarding zlib. On Debian/Ubuntu, zlib1g-dev is a dependency of r-base as
*** shown by 'apt-cache showsrc r-base | grep ^Build-Depends | grep zlib', and therefore
*** 'sudo apt-get build-dep r-base' should be sufficient too.
*** To silence this message, please ensure that :
*** 1) 'pkg-config --exists zlib' succeeds (i.e. $? -eq 0)
*** 2) 'pkg-config --libs zlib' contains -lz
*** Compilation will now be attempted ...
R CMD SHLIB supports OpenMP without any extra hint

问题：
(1) 它说 pkg-config not installed。但它是，在 /opt/homebrew/bin/pkg-config 中。
(2) 它似乎是在尝试为我的芯片编译，而不是为翻译的 x86_84 芯片编译。但是 RStudio 在 Rosetta 上运行。
