Question

我正在尝试为R中的Rserve包编写第一个公式：https://www.rforge.net/Rserve/。

到目前为止，我有这个：

# Documentation: https://docs.brew.sh/Formula-Cookbook
#                https://www.rubydoc.info/github/Homebrew/brew/master/Formula
class Rserve < Formula
  desc "Rserve acts as a socket server (TCP/IP or local sockets) which allows binary requests to be sent to R."
  homepage "http://www.rforge.net/Rserve/"
  url "https://cran.r-project.org/src/contrib/Rserve_1.7-3.tar.gz"
  sha256 "f6d636c736c3f16487d9987e54554fe0c55257b9bc0671b43e536d832e513027"

  depends_on "r"
  depends_on "gettext"

  def install
    system("whoami")
    system("#{HOMEBREW_PREFIX}/bin/R CMD install --configure-args=\"CPPFLAGS=-L#{HOMEBREW_PREFIX}/opt/gettext/lib LDFLAGS=-I#{HOMEBREW_PREFIX}/opt/gettext/include\" .")
  end

  test do
    # `test do` will create, run in and delete a temporary directory.
    #
    # This test will fail and we won't accept that! For Homebrew/homebrew-core
    # this will need to be a test that verifies the functionality of the
    # software. Run the test with `brew test Rserve`. Options passed
    # to `brew install` such as `--HEAD` also need to be provided to `brew test`.
    #
    # The installed folder is not in the path, so use the entire path to any
    # executables being tested: `system "#{bin}/program", "do", "something"`.
    system "false"
  end
end

我得到的错误是：

drwxr-xr-x  3 kwilliams  admin  96 Jan 14 13:38 ../

如果我将自己放在Rserve tarball的新目录中，然后手动运行命令/usr/local/bin/R CMD install --configure-args="CPPFLAGS=-L/usr/local/opt/gettext/lib LDFLAGS=-I/usr/local/opt/gettext/include" .，则不会收到有关“无权安装到目录”的错误信息

与我在shell中运行它相比，Homebrew在运行该命令的环境有什么不同？

我的brew doctor输出是干净的，除了警告我的docker桶已断开链接外，我认为这是不相关的。

弄清楚了-有一个沙箱（我认为是Class Age City Color Count 0 A 20 Los Angeles Blue 2 1 A 20 Los Angeles Red 1 2 B 25 Phoenix Yellow 1，它限制了对前缀目录外部文件系统的写入：

https://discourse.brew.sh/t/potential-permission-issues-in-a-formula-im-writing/3707

我需要找出将文件写入sandbox-exec的正确方法，或者从Cellar目录或其任何文件将它们符号链接到那里。

自制软件：安装时缺少权限
