Mac下Flutter环境配置问题

附上Flutter中文文档，文档还是很全面的。

iOS真机环境:The brew link step did not complete successfully

1、bin/2to3

$ brew install --HEAD libimobiledevice
//
==> Pouring python-3.7.2_2.mojave.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/2to3
Target /usr/local/bin/2to3

already exists. You may want to remove it:
  rm '/usr/local/bin/2to3'

To force the link and overwrite all conflicting files:
  brew link --overwrite python

To list all files that would be deleted:
  brew link --overwrite --dry-run python
------------------------------------------------------------------------------------------
$ rm '/usr/local/bin/2to3' //删除2to3
$ brew link --overwrite python
Linking /usr/local/Cellar/python/3.7.2_2... 24 symlinks created
$ python -V
Python 2.7.10
$python3 -V
Python 3.6.4rc1

通过安装包安装的都会在下面的目录下：
/Library/Frameworks/Python.framework/Versions/3.6
通过brew 安装的都会在
/usr/local/Cellar/python/3.7.2_2

为什么python版本不是3.7.2？

2、bin/pod

$ brew install ideviceinstaller ios-deploy cocoapods
//
==> Pouring cocoapods-1.6.1.mojave.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/pod
Target /usr/local/bin/pod
already exists. You may want to remove it:
  rm '/usr/local/bin/pod'

To force the link and overwrite all conflicting files:
  brew link --overwrite cocoapods

To list all files that would be deleted:
  brew link --overwrite --dry-run cocoapods
------------------------------------------------------------------------------------------
$ brew link --overwrite cocoapods
Linking /usr/local/Cellar/cocoapods/1.6.1... 2 symlinks created

第一次使用vscode，不知道有没有像我一样Flutter: New Project之后找不到输入项目名称的地方。下意识以为会有一个弹框的。。。然而依然在原来输入框中。。。怪我没认真看英文。。。
