Verify installation

To verify that dvm has been installed, do:

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

.dvmrc

You can let dvm to writing config to current directery by add the --local flag to dvm use. Afterwards, dvm use, dvm install will use the version specified in the .dvmrc file if no version is supplied on the command line.

For example, to make dvm default to the 1.17.0 release for the current directory:

dvm use --local 1.17.0

Then when someone else with a copy of your project and run dvm:

$ 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

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

Caveats

unzip is required

The program unzip is a requirement for the Shell installer.

$ 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).

Powershell on Windows is required

Currently, we use PowerShell profile to set environment variables due to various reasons, so it's required.
