Installs code-server for Linux or macOS.
Installs code-server for Linux and macOS.
It tries to use the system package manager if possible.
After successful installation it explains how to start using code-server.
${curl_usage-}
Usage:
$cli [--dry-run] [--version X.X.X] [--static <install-prefix>=~/.local]
$arg0 [--dry-run] [--version X.X.X] [--method detect] [--prefix ~/.local]
--dry-run Echo the commands for the install process without running them.
--version Install a specific version instead of the latest release.
--static Install a static release into ~/.local
The release will be unarchived into ~/.local/lib/code-server.X.X.X
and the binary symlinked into ~/.local/bin/code-server.
Add ~/.local/bin to your \$PATH to use it.
To install system wide pass ---static=/usr/local
--dry-run
Echo the commands for the install process without running them.
--version X.X.X
Install a specific version instead of the latest.
--method [detect | archive]
Choose the installation method. Defaults to detect.
- detect detects the system package manager and tries to use it.
Full reference on the process is further below.
- archive installs a static release archive into ~/.local
Add ~/.local/bin to your \$PATH to use it.
--prefix <dir>
Sets the prefix used by static release archives. Defaults to ~/.local
The release is unarchived into ~/.local/lib/code-server-X.X.X
and the binary symlinked into ~/.local/bin/code-server
To install system wide pass ---prefix=/usr/local
- For Debian, Ubuntu and Raspbian it will install the latest deb package.
- For Fedora, CentOS, RHEL and openSUSE it will install the latest rpm package.
- For Arch Linux it will install the AUR package.
- For any unrecognized Linux operating system it will install the latest static
release into ~/.local
- Add ~/.local/bin to your \$PATH to run code-server.
- For macOS it will install the Homebrew package.
- If Homebrew is not installed it will install the latest static release
into ~/.local
- Add ~/.local/bin to your \$PATH to run code-server.
- If ran on an architecture with no binary releases, it will install the
npm package with yarn or npm.
- We only have binary releases for amd64 and arm64 presently.
It will cache all downloaded assets into ~/.cache/code-server
