FLAC在Linux中安裝-Please install ‘flac’ on ALL worker nodes

在跑librispeech的時候，下載好數據會提示Please install ‘flac’ on ALL worker nodes!
這是因爲數據集是flac的壓縮格式，而Linux系統沒有安裝解碼的軟件，所以我們需要安裝flac。

第一步 下載

wget  https://downloads.xiph.org/releases/flac/flac-1.3.2.tar.xz 

第二步 解壓

下載下來的文件是 .tar.xz 格式的壓縮包,進入到下載目錄

$ xz -d flac-1.3.2.tar.xz 
$ tar -xvf flac-1.3.2.tar

第三步 安裝（如果你有root權限可去掉步驟一中–prefix命令）

./configure --prefix=/usr/*** &&#在自己的目錄中安裝此軟件
make
make install

第四步 source

把你安裝的路徑中有個 bin 文件夾，放到環境變量中( .bash 或者 .bash_profile)。

source .bash 或者 source .bash_profile

第五步 測試

[rookie@tiger02 ~]$ flac
