验证安装

要验证dvm是否已安装，请执行以下操作

dvm -V

如果安装成功，应输出dvm的版本。

初始化

调用 dvm 将在不存在的情况下创建一个 ~/.dvm/ 目录，并将所有已安装的Deno版本放入 ~/.dvm。

➜  ~  dvm
Creating /Users/justjavac/.dvm

.dvmrc

您可以通过在 dvm use 中添加 --local 标志来让dvm将配置写入当前目录。之后，dvm use 和 dvm install 将使用 .dvmrc 文件中指定的版本，如果命令行上没有提供版本。

例如，要将dvm默认设置为当前目录的 1.17.0 版本

dvm use --local 1.17.0

$ dvm use
No version input detect, try to use version in .dvmrc file
Using semver range: 1.17.0
Writing to home folder config
Now using deno 1.17.0

➜  ~  dvm list
 * 0.1.0
   0.1.1
   0.1.2

➜  ~  dvm use 1.1.0
now use deno 1.1.0
➜  ~  dvm use 1.2.0
deno v1.2.0 is not installed. Use `dvm install 1.2.0` to install it first.

$ curl -fsSL https://deno.land/x/dvm/install.sh | sh
Error: unzip is required to install dvm (see: https://github.com/justjavac/dvm#unzip-is-required).
