Mac configuration flutter

1, go to the official website to download the recommended speed is not slow at:

https://flutter.io/setup-macos/

Configuration environment variable, here I use the command line:

vim ~/.bash_profile

Adding environment configuration

export PATH=/你的flutter文件夹所在位置/flutter/bin:$PATH

Save it, note that if this file does not exist, then create a new one. After running the command has been saved:

source ~/.bash_profile

This time should be able to run the command flutter, we run the command line:

flutter -h

Looks so simple: pit but still a lot of
pit 1, .bash_profile file does not exist create a

touch .bash_profile

Add the following configuration

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=/Users/ruihe/Downloads/flutter/bin:$PATH

Pit 2,
MacBook-Pro: xxxx ~ $ Flutter -h
-bash: Flutter: the Command not found
then downloaded to copy files to other went inside run source ~/.bash_profilehas been holding this wrong, tangled for a long time, and finally re-download a directly the download path / Users / xxxx / Downloads / set inside,
xxxxxx $ Open ~ / .bash_profile
xxxxxx $ Source .bash_profile
xxxxxx $ Source ~ / .bash_profile
mainly 2 and 3 do not know that is right, it is a bit run together
pit 3,
