三步解决 command not found: flutter

此方案为mac环境适用

step 1

找到你的flutter安装目录，我的是这样的

/Users/junhualiu/Development/flutter

在此文件夹下运行

flutter -h

不出意外，会出现flutter的命令提示文本

Common commands:

  flutter create <output directory>
    Create a new Flutter project in the specified directory.

  flutter run [options]
    Run your Flutter application on an attached device or in an emulator.

Usage: flutter <command> [arguments]....................................
.................

若是没有出现，请使用

export PATH=`pwd`/flutter/bin:$PATH

若此步骤后flutter -h还是无效，我建议你重装flutter。

step 2

打开terminal窗口输入sudo nano /etc/paths

step 3

将你的flutter bin所在绝对路径填入，比如：我的是/Users/junhualiu/Development/flutter/bin 所以填入

/Users/junhualiu/Development/flutter/bin

然后ctrl+x保存，会询问你是否确定保存，接下来按y,然后回车enter。 关闭terminal重新打开，输入flutter -h看看是不是生效辣？
