第一次安装brew

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 https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

结果报错：

#!/usr/bin/ruby

STDERR.print <<EOS
Warning: The Ruby Homebrew installer is now deprecated and has been rewritten in
Bash. Please migrate to the following command:
  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

EOS

Kernel.exec "/bin/bash", "-c", '/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"'

解决：

点击：https://raw.githubusercontent.com/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：

#!/bin/bash
set -u

接着直接打开install.sh：更换源：

找到BREW_REPO = “https://github.com/Homebrew/brew”，将其换为：BREW_REPO = “https://mirrors.ustc.edu.cn/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.sh
drwxr-xr-x   13 robin  staff    416  8 26 15:27 nltk_data
drwxr-xr-x    8 robin  staff    256  1 13  2020 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.sh
drwxr-xr-x   13 robin  staff    416  8 26 15:27 nltk_data
drwxr-xr-x    8 robin  staff    256  1 13  2020 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: b065e5e3783954f3e65d8d3a6377ca51649bfcfa21b356b0dd70490f74c6bd86
  Actual: b8f3cdae600cbf8ee78f0f2c28c06a0a1c26e4783296c2c23b3763bf48988ffa
 Archive: /Users/robin/Library/Caches/Homebrew/portable-ruby-2.6.3_2.yosemite.bottle.tar.gz
To 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 https://homebrew.bintray.com/bottles-portable-ruby/portable-ruby-2.6.3_2.yosemite.bottle.tar.gz

好在继续往前推进了：

######################################################################## 100.0%
==> Pouring portable-ruby-2.6.3_2.yosemite.bottle.tar.gz
==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
  https://github.com/Homebrew/brew#donations
==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...

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 homebrew
git clone git://mirrors.ustc.edu.cn/homebrew-core.git

效果：

在这里插入图片描述

结果：Checking out files: 100% (5455/5455), done.

在这里插入图片描述

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 2.4.13
Homebrew/homebrew-core (git revision b022a; last commit 2020-08-26)

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 "$(brew --repo)" remote set-url origin https://mirrors.ustc.edu.cn/brew.git
  • 替换 homebrew-core.git：
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

按需配置

git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.ustc.edu.cn/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！）

参考：

  1. Mac下安装Homebrew的经历
  2. 最新homebrew安装方法（四小时踩坑成果）
  3. 报错-bash: ./a.sh: Permission denied
  4. Warning: The Ruby Homebrew installer is now deprecated and has been rewritten in Bash.

Power domain 划分该如何下手

假如PD1比PD3更always on的话，我们只需要插入普通buffer即可，因为PD3 on，PD1也肯定是ON，PD1 off，PD3肯定时off，PD1能cover PD3的电源情况，因此使用普通buffer也可，但是处于省电角度，我们还是使用AO buffer；在我们做多power domain时，在切分power domain时，需要谨慎，稍有不慎，就会出现congestion以及timing问题，那问题来了，我们在切分power domain时有什么考究么，今天小编就和大家一起讨论讨论。

摘要： Godot引擎版本选择需根据项目需求权衡3.x与4.x。Godot4.x（如4.2）适合3D开发和新项目，支持Vulkan和GDScript2.0，但生态尚不成熟；Godot3.x（如3.5.3）则更适合稳定2D开发、Web导出及依赖现有插件/教程的场景。安装方式极简，官网下载解压即可运行。新手建议：短期高效选3.x，长期探索选4.x，旧项目勿盲目迁移。附版本对比表及决策树，助开发者快速匹配需求。
