homebrew的安装和使用

安装brew

安装homebrew之前最好是执行以下语句:

git config --global http.postBuffer 542428800

否则的话很有可能会报错:

RPC failed; curl 18 transfer closed with outstandingreaddata remaining

然后执行安装命令:

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

如果一不小心先执行安装命令了,安装过程可能会遇到以下报错

touch: /Users/mac/Library/Caches/Homebrew/.cleaned: Permission denied

Failed during: /usr/bin/touch /Users/mac/Library/Caches/Homebrew/.cleaned

遇到此问题,请把文件读写权限打开,可以使用以下命令:

1. sudo chmod 777 /Users/mac/Library/Caches/Homebrew/.cleaned

2. sudo chmod -R g+w /Users/mac/Library/Caches/Homebrew/.cleaned

但是其实用官网的下载地址会很慢很慢,如果网速快的话还能接受,所以可以采用国内镜像的方式下载,按照参考地址一步一步安装就行,不需要卸载homebrew。

步骤如下:

1. cd ~

2. curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_install

3. /usr/bin/ruby ~/brew_install

.........

直到看到 Install Successfully!的语句才算安装成功。
