升級到MacOS High Sierra? ftp會不見哦！

今天忍不住了，還是升級到MacOS High Sierra
果然沒事找事，一升級就會出問題！

居然終端機裡的ftp不見了，當下心想，又是Apple自己改的！
找了一下，果然如此：

那怎麼辦呢？
上面討論串的最後，有朋友提了一個方法，就是安裝LFTP來頂著用：

$ brew install inetutils

will install inetutils from GNU that includes /usr/local/bin/ftp

$ which ftp

/usr/local/bin/ftp

$ ftp --version

ftp (GNU inetutils) 1.9.4

要先安裝brew:
https://brew.sh/

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

順利裝好。

然後下 $ brew install inetutils
結果：

Error: Your Xcode (8.2) is too outdated.

Please update to Xcode 9.1 (or delete it).

Xcode can be updated from the App Store.

原因是之前為了玩深度學習Tensorflow的nVidia GPU計算功能，把xcode command line工具的路徑固定到8.2版去了，那現在只好改回來：

$ sudo xcode-select --switch /Applications/Xcode.app

再重下之前指令，就好了：

$ brew install inetutils
