dart run build_runner build

使用如上命令，导致无法进行rebuild，异常如下

Resolving dependencies in /Users/gaoxiaoxiong/project/flutter/myFirst_flutter... 
Because myFirst_flutter depends on flutter_test from sdk which doesn't exist (the Flutter SDK is not available), version solving failed.
Flutter users should use `flutter pub` instead of `dart pub`.

我环境变量里面配置的dart版本，跟我fvm全局配置的dart版本不同导致。因为我以前使用homebrew 进行安装的

brew remove dart  //删除已安装的

fvm环境配置

export FVM_HOME="$HOME/fvm"
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH="$HOME/fvm/default/bin:$PATH" //表示使用全局默认配置的版本
