fvm
命令：pub global activate fvm
$ pub global activate fvm
Package fvm is currently active at version 2.0.5.
Resolving dependencies... (3.4s)
The package fvm is already activated at newest available version.
To recompile executables, first run `global decativate fvm`.
Installed executable fvm.
Warning: Pub installs executables into $HOME/.pub-cache/bin, which is not on your path.
You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.):export PATH="$PATH":"$HOME/.pub-cache/bin"Activated fvm 2.0.5.
- 配置
.bash_profile中添加：
# fvm
export PATH="$PATH":"$HOME/.pub-cache/bin"
使.bash_profile生效：
source ~/.bash_profile
重启命令行工具，执行fvm：
$ fvm

fvm官方使用文档
- 配置
fvm缓存路径（可选，默认在用户目录下fvm/versions文件夹）：
fvm config --cache-path <CACHE_PATH>
- 查看当前安装的flutter版本：
$ fvm listNo SDKs have been installed yet. Flutter. SDKs installed outside of fvm
will not be displayed.
- 安装指定版本的flutter：
$ fvm install 2.2.1
Flutter "2.2.1" is not installed.Installing version: 2.2.1...
Cloning into '/Users/yuanzhiying/fvm/versions/2.2.1'...
- 删除指定版本：
$ fvm remove 2.2.0
Removing 2.2.0...
2.2.0 removed.
此时会在用户目录下自动创建fvm/versions/2.2.1文件夹，如果本地已有flutter，可将本地的flutter拷贝到versions目录下，文件夹改为对应的版本名。当前flutter版本可以在flutter根目录下的version文件里查看。
/Users/yuanzhiying/fvm/versions/1.22.6
- 查看汇漫网已安装的flutter版本：
$ fvm list

$ cd mobile_life/info_valley
$ fvm use 1.22.6

重启Android studio。
flutter命令的使用
此时执行flutter doctor找不到flutter命令：
$ flutter doctor
zsh: command not found: flutter
所有flutter命令前加上fvm即可：
$ fvm flutter doctor

$ fvm flutter pub get
Running "flutter pub get" in info_valley... 1.4s
flutter下dart命令的使用
所有dart命令前加上fvm即可：
$ fvm dart --version
fvm: running Dart from Flutter "1.22.6"Dart SDK version: 2.10.5 (stable) (Tue Jan 19 13:05:37 2021 +0100) on "macos_x64"
- 便捷使用命令
在.bash_profile中设置命令的别名：
# aliases 快捷使用fvm命令
alias f="fvm flutter"
alias d="fvm dart"
使生效：
source ~/.bash_profile
重启命令行工具。
$ f pub get
Running "flutter pub get" in info_valley... 1.0s
$ d --version
Running using Flutter version configured in path.Dart SDK version: 2.13.1 (stable) (Fri May 21 12:45:36 2021 +0200) on "macos_x64"
- 设置全局默认的flutter版本
$ fvm global 1.22.6
Flutter "1.22.6" has been set as global
However your "flutter" path current points to:.
to use global Flutter SDK through FVM you should change it to:/Users/yuanzhiying/fvm/default/bin
此时fvm目录下自动生成了一个default的快捷文件夹。
