1.下载flutter
推荐去官网下载,速度并不慢,网址:
https://flutter.io/setup-macos/
2.配置环境变量
先把刚才下载的flutter_macos_vxxx.zip解压缩,笔者选择使用的目录是根目录下的APP文件夹。这个路径要用到。
配置环境变量,这里笔者使用命令行:
vim ~/.bash_profile
使用镜像
由于在国内访问Flutter有时可能会受到限制,Flutter官方为中国开发者搭建了临时镜像,大家可以将如下环境变量加入到用户环境变量中:
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
增加一行:
export PATH=/Users/abc/APP/flutter/bin:$PATH
保存一下,注意如果这个文件不存在,那么就新建一个。保存完毕之后运行命令:
source ~/.bash_profile
这个时候应该能运行flutter命令了,我们运行命令行:
flutter -h
3.检查环境
运行命令行:
flutter doctor
按照检测结果的说明,如果有[!] ✗ 标志,表示本行检测不通过,需要做一些设置或者安装一些软件。
1.下载并安装 Android Studio from: https://developer.android.com/studio/index.html
在配置文件里,配置Android SDK的路径
export ANDROID_HOME="/Users/abc/Library/Android/sdk"
export PATH=${PATH}:${ANDROID_HOME}/tools
export PATH=${PATH}:${ANDROID_HOME}/platform-tools
2.再下载添加插件:
[✓] Android Studio (version 3.0)
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
1.打开android studio, 打开plugin
2.输入flutter搜索,install
3.配置android,一路点y即可。
flutter doctor --android-licenses
再次运行
flutter doctor
$ brew update
-bash: brew: command not found
安装brew
电脑没有安装过brew,那就进行安装。
尝试1
:去官网https://brew.sh/下载,但是在终端中执行命令行,老是报错。意思大致是连不上'raw.githubusercontent.com'这个域名的服务器。
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
curl: (51) SSL: no alternative certificate subject name matches target host name 'raw.githubusercontent.com'
尝试2
:那就换一种方式,使用安装文件进行安装
1.先把https://raw.githubusercontent.com/Homebrew/install/master/install文件下载下来(使用浏览器打开,另存为也可以),把文件命名为install.txt
。
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
ruby install.txt文件的绝对路径
第一行的rm命令,是为了防止之前你安装Homebrew失败而残留的文件,导致这次安装失败。
ruby install.txt执行之后,安装命令行提示安装,应该会安装成功。
安装成功后,执行以下命令检测:
$ brew doctor
Your system is ready to brew.
brew就安装成功了!
再次运行
flutter doctor
按照提示去运行命令行:
