第一次安装brew
使用官网的安装方法：结果报错：解决： 接着直接打开`install.sh`：更换源：接着在终端使用`cd ~`进入home目录，执行`install.sh`，结果失败：看来是权限不够，咋办？ 最后的选择还是报错了：`Error: Checksum mismatch.`应该是在Cloning into...处卡主了，结果：Checking out files: 100% (5455/5455), done.验证安装配置环境变量必备设置按需配置 写在最后仅仅是为了方便在Mac上安装sox！
使用官网的安装方法：
/bin/bash -c "$(curl -fsSL /Homebrew/install/master/install.sh)"
结果报错：
#!/usr/bin/rubySTDERR.print <<EOSWarning: The Ruby Homebrew installer is now deprecated and has been rewritten inBash. Please migrate to the following command:/bin/bash -c "$(curl -fsSL /Homebrew/install/master/install.sh)"EOSKernel.exec "/bin/bash", "-c", '/bin/bash -c "$(curl -fsSL /Homebrew/install/master/install.sh)"'
解决：
点击：/Homebrew/install/master/install.sh，command s将install.sh保存到本地；
附：如果没有的话可以直接复制我这个：

接着直接打开install.sh：更换源：
找到BREW_REPO = “/Homebrew/brew”，将其换为：BREW_REPO = “https://mirrors./brew.git”；
接着在终端使用cd ~进入home目录，执行install.sh，
结果失败：
-bash: install.sh: command not found
尝试解决：使用./install.sh，
出现新的报错：
-bash: ./install.sh: Permission denied
看来是权限不够，咋办？
解决：
在终端输入ll或者ls -l查看文件的访问权限，
-rw-r--r--@ 1 robin staff 19082 8 26 19:39 install.shdrwxr-xr-x 13 robin staff 416 8 26 15:27 nltk_datadrwxr-xr-x 8 robin staff 256 1 13 seaborn-data
r可读，w可写，但是不可执行，通过执行代码chmod u+x install.sh赋予执行权限：
-rwxr--r--@ 1 robin staff 19082 8 26 19:39 install.shdrwxr-xr-x 13 robin staff 416 8 26 15:27 nltk_datadrwxr-xr-x 8 robin staff 256 1 13 seaborn-data
然后可以执行install.sh
也就需要执行./install.sh，输入密码后：

一路执行，知道现在还在下载之中…
慢一点没事，希望顺利一步到位！
若不行，
最后的选择
Mac 安装 brew（最新教程，绝对可行，一行代码搞定，不报错）
还是报错了：Error: Checksum mismatch.
Error: Checksum mismatch.Expected: b065e5e3783954f3e65d8d3a6377ca51649bfcfa21b356b0dd70490f74c6bd86Actual: b8f3cdae600cbf8ee78f0f2c28c06a0a1c26e4783296c2c23b3763bf48988ffaArchive: /Users/robin/Library/Caches/Homebrew/portable-ruby-2.6.3_2.yosemite.bottle.tar.gzTo retry an incomplete download, remove the file above.Error: Failed to install Homebrew Portable Ruby (and your system version is too old)!Failed during: /usr/local/bin/brew update --force
查了一下，是由Homebrew目录下的portable-ruby-2.6.3_2.yosemite.bottle.tar.gz文件引起的安装中断，只需要到上面对应的路径里，使用rm删掉这个文件，重新执行安装命令即可。
这里我不知道要具体使用什么安装命令，所以又重新执行了./install.sh：
结果很奇怪，经过开始的下载安装之后，又开始下载这个：
HEAD is now at 04382c8d0 Merge pull request #8470 from dtrodrigues/sha-tag==> Downloading /bottles-portable-ruby/portable-ruby-2.6.3_2.yosemite.bottle.tar.gz
好在继续往前推进了：

应该是在Cloning into…处卡主了，
等了一会，下载速度也是机器的慢！
解决办法：立马用Control + C中断脚本，然后执行以下命令：
cd "$(brew --repo)/Library/Taps/"mkdir homebrew && cd homebrewgit clone git://mirrors./homebrew-core.git
效果：
结果：Checking out files: 100% (5455/5455), done.
注：最后出现 Installation successful! 或者 Checking out files: 100% (5392/5392), done. 说明安装成功。
（最后再重新执行脚本./install.sh）好像不需要这个了！
验证安装
通过brew -v查看一下是否成功:
Homebrew 2.4.13Homebrew/homebrew-core (git revision b022a; last commit -08-26)
记得安装后取设置环境变量！
配置环境变量
前面已经提到，Homebrew通常用来下载软件的，但它在安装软件时非常慢。为了提升安装速度，需要更改 Homebrew 的安装源，将其替换成国内镜像。
这里用的是由中科大负责托管维护的 Homebrew 镜像。其中，前两个为必须配置的项目，后两个可按需配置。
必备设置
替换 brew.git：git -C "$(brew --repo)" remote set-url origin https://mirrors./brew.git
替换 homebrew-core.git：
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors./homebrew-core.git
按需配置
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors./homebrew-core.git

写在最后
用了Mac这么久，但是之前一直是使用pip和conda来安装各种工具，今天终于打破了不使用brew的想法…（该来的早晚要来！）
