安装程序如何在Mac OSX上设置PATH变量?

I'm wondering how PATH variable is set by Mac Installers on Mac OSX.

For example:

Look at golang Mac OSX Installer. From the link

Mac OS X package installer

Download the package file, open it, and follow the prompts to install the Go tools. The package installs the Go distribution to /usr/local/go.

The package should put the /usr/local/go/bin directory in your PATH environment variable. You may need to restart any open Terminal sessions for the change to take effect.

So, the I can see /usr/local/go/bin in $PATH but it's not being set in .profile, .bashrc or launchd.conf.

Can anybody please help me to understand?

我想知道Mac OSX上的Mac Installers如何设置PATH变量。


查看golang Mac OSX安装程序。 从链接

Mac OS X软件包安装程序

下载软件包文件,将其打开,然后按照提示安装Gon工具。 该软件包将Go发行版安装到 /usr/local/go。

该软件包应将/ usr / local / go / bin目录放在PATH 环境变量中。 您可能需要重新启动所有打开的Terminal 会话,以使更改生效。

因此,我可以在/ usr / local / go / bin中看到 $ PATH,但未在.profile,.bashrc或launchd.conf中设置。

    There are a couple methods of setting environment variables in Mac OS X (lots of discussion here). In the case the Go package, it is adding a file in /etc/paths.d named go that contains /usr/local/go/bin. Here's an answer to another question explaining that a utility called path_helper is being launched and it's inspecting the /etc/paths.d directory.

    You can verify this yourself by using an application called Pacifist to inspect the contents of the Go package and looking at the files it's installing.
