upgrading console emacs (/usr/bin/emacs) on Mac
提问by eugene
I extensively use /usr/bin/emacsin Terminal.
我/usr/bin/emacs在终端中广泛使用。
I have Emacs 22 and I'd like to upgrade it to 23. I wonder how to do it.
Googling "emacs download mac" gives me Emacs.appwhich has its own window and user interface, but I don't want that.
我有 Emacs 22，我想将它升级到 23。我想知道如何去做。
谷歌搜索“emacs 下载 mac”给了我Emacs.app它有自己的窗口和用户界面，但我不想要那个。
I am not sure how I have /usr/bin/emacs in the first place, maybe it came with Mac OS?
我不确定我是如何拥有 /usr/bin/emacs 的，也许它是 Mac OS 附带的？

You can run the Emacs.app version in a terminal like this:
您可以在终端中运行 Emacs.app 版本，如下所示：
/Applications/Emacs.app/Contents/MacOS/Emacs -nw
In my .cshrc file, I use an alias to make this easier to invoke:
在我的 .cshrc 文件中，我使用别名来使调用更容易：
alias enw '/Applications/Emacs.app/Contents/MacOS/Emacs -nw'

It is a standard editor included with OS X and a lot of other *nix systems along with vi/vim, and pico. Personally i wouldnt upgrade the pre-installed one. I would install from Macports, Fink, or Homebrew or compile from source myself to a different location (like /usr/local).
它是 OS X 和许多其他 *nix 系统以及 vi/vim 和 pico 中包含的标准编辑器。我个人不会升级预装的。我会从 Macports、Fink 或 Homebrew 安装，或者自己从源代码编译到不同的位置（如/usr/local）。

I was on this same search and ended up installing with Homebrewso I could get the latest version along with several libraries, as described in this answerat the Emacs Stack Exchangesite:
我进行了同样的搜索，最终安装了Homebrew，因此我可以获得最新版本和几个库，如Emacs Stack Exchange站点上的这个答案中所述：
Nowadays, I use just GNU Emacs snapshot builds. These have reasonably good OS X support, and are by far the easiest to install, and best supported by the community.
I used to get them from Emacs for Mac OS X, but now I use Homebrew, because it supports more libraries, notably GNU TLS for encrypted network connections.
All in all: Use
brew install emacs --HEAD --use-git-head --with-cocoa --with-gnutls --with-rsvg --with-imagemagick:).
现在，我只使用 GNU Emacs 快照构建。它们具有相当不错的 OS X 支持，并且是迄今为止最容易安装的，并且得到社区的最佳支持。
我曾经从 Mac OS X 的 Emacs 获取它们，但现在我使用 Homebrew，因为它支持更多的库，特别是用于加密网络连接的 GNU TLS。
总而言之：使用
brew install emacs --HEAD --use-git-head --with-cocoa --with-gnutls --with-rsvg --with-imagemagick:)。
(Note that GNU Emacs is what comes preinstalled on Mac OS X, at least on mine as of 10.10.5)
（请注意 GNU Emacs 是预装在 Mac OS X 上的，至少在我的 10.10.5 上是这样）
This added a new Emacs binary at /usr/local/bin/emacs, leaving the existing installation and /usr/bin/emacsin place.
这在 中添加了一个新的 Emacs 二进制文件/usr/local/bin/emacs，保留了现有的安装/usr/bin/emacs。

I created a symlink in /usr/local/binpointing to the new version of emacs which was in Applications/Emacs.app/Contents/MacOS/
我创建了一个符号链接，/usr/local/bin指向新版本的 emacsApplications/Emacs.app/Contents/MacOS/
