1. MacOs Dart环境安装

前置材料：需要安装dart的Mac设备, 一颗会用搜索引擎的聪明大脑

一步步讲一下homebrew的安装流程

我个人安装时遇到的情况 大家做个参考 如果你遇到的问题和我的不一样

可以来这里 homebrew快速安装指引 可入群咨询

---

首先, 我其实是安装过homebrew的

网上常见的dart安装命令如下

brew tap dart-lang/dart
brew install dart

所以我一开始是直接执行

brew tap dart-lang/dart
# 不出意外的报错了 报错信息如下
# ==> Tapping dart-lang/dart
## Cloning into '/usr/local/Homebrew/Library/Taps/dart-lang/homebrew-dart'...
## fatal: unable to access 'https://github.com/dart-lang/homebrew-dart/': HTTP/2 stream 1 was not closed cleanly before end of the underlying stream
## Error: Failure while executing; `git clone https://github.com/dart-lang/homebrew-dart /usr/local/Homebrew/Library/Taps/dart-lang/homebrew-dart --origin=origin --template=` exited with 128.

然后去搜解决方案

---

方案一

sudo chown -R $(whoami) $(brew --prefix)/*
# 执行完之后重新 brew tap dart-lang/dart
# 没有生效

---

方案二

cd /usr/local/Homebrew/Library/Taps/
cd homebrew
brew update
# brew 更新成功了 日志如下
## Updated 2 taps (homebrew/core and homebrew/cask).
## ==> New Formulae
## aarch64-elf-binutils                     livekit-cli
## aarch64-elf-gcc                          llama
## abi-compliance-checker                   llvm@12
## abi-dumper                               llvm@13
## abricate                                 llvm@14
## acl                                      lmfit
## ...                                      ...
## ...                                      ...
## ==> Outdated Formulae
## gettext   git       icu4c     node      nvm       p7zip     pcre2     yarn
## 
## You have 8 outdated formulae installed.
## You can upgrade them with brew upgrade
## or list them with brew outdated.

我很开心的以为这就OK了, 然后继续执行

brew tap dart-lang/dart
# 居然又报错了 这次是不一样的报错信息
## Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!
## Please create a new installation in /opt/homebrew using one of the
## "Alternative Installs" from:
##   https://docs.brew.sh/Installation
## You can migrate your previously installed formula list with:
##   brew bundle dump

我tm

原来是因为

我原来的设备是intel内核的Mac，换到这台M1的时候直接用了数据迁移

而M1的homebrew和intel的homebrew是不太一样的

原来的homebrew能用，但是不完全能用。

好吧好吧

然后我又开始解决这个问题

方案一

来自stackoverflow的大神方案

当我看到 Downloading and installing Homebrew...

我以为终于OK了

然而 现实又给了我沉重的一击

fatal: 无法访问 'https://github.com/Homebrew/brew/'：HTTP/2 stream 1 was not closed cleanly before end of the underlying stream

官方的镜像死活连不上

继续找

方案二

把镜像源改到中科大

传送门

执行以下命令

git -C "$(brew --repo)" remote set-url origin https://mirrors.ustc.edu.cn/brew.git
git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles/bottles' >> ~/.zprofile
source ~/.zprofile
# 以上命令执行完后均不会有任何提示

执行完后 再次安装brew

arch -x86_64 /bin/bash -c "$(curl -fsSL https://gitee.com/ineo6/homebrew-install/raw/master/install.sh)"
# 终于搞定了 日志如下
## ==> Checking for `sudo` access (which may request your password)...
