我正在使用 macOSCatalina和 Nix 2.3.12。
我正在更新bash到最新版本（通过 Nix）。我可以成功安装它，并且它会加载 Nix 安装的版本，但是如果我尝试使用 Bash 5.x（更新版本）中的任何功能，我将无法使用，除非.bashrc是源代码 — 这又是 Nix 的源代码。
我的来源.bashrc（.bash_profile仅包含此内容）：
#
# ~/.bash_profile
#
[ -f "${HOME}/.bashrc" ] && . "${HOME}/.bashrc"
有没有办法在所有这些发生之前加载更新版本？
即使我/etc/shells使用新bash位置更新文件并尝试chsh -s /Users/x80486/.nix-profile/bin/bash这样做也不起作用。
.bashrc这是我的文件的内容：
#
# ~/.bashrc
