```
### Verify installation
To verify that dvm has been installed, do:
```bash
dvm -V
```
which should output dvm's version if the installation was successful.
### Initialisation
Calling `dvm` will creates an `~/.dvm/` directory if it doesn't exist,
and all installed versions of deno will put into `~/.dvm`.
```
➜ ~ dvm
Creating /Users/justjavac/.dvm
```
## Example
### Listing versions
List all installed versions:
```
➜ ~ dvm list
* 0.1.0
0.1.1
0.1.2
```
The version with a asterisk(`*`) means that this version is the version currently in use.
### Switching version
```
➜ ~ 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.
```
## Compatibility
- The Shell installer can be used on Windows with [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/about), [MSYS](https://www.msys2.org) or equivalent set of tools.
## Known Issues
### unzip is required
The program [`unzip`](https://linux.die.net/man/1/unzip) is a requirement for the Shell installer.
```sh
$ 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).
```
**When does this issue occur?**
During the `install.sh` process, `unzip` is used to extract the zip archive.
**How can this issue be fixed?**
You can install unzip via `brew install unzip` on MacOS or `apt-get install unzip -y` on Linux(Ubuntu,Debian,Deepin).
