|
Installs code-server for Linux, macOS and FreeBSD. |
|
|
|
It tries to use the system package manager if possible. |
|
|
|
After successful installation it explains how to start using code-server. |
|
|
|
Pass in user@host to install code-server on user@host over ssh. |
|
|
|
The remote host must have internet access. |
|
|
|
${not_curl_usage-} |
|
|
|
Usage: |
|
|
|
$arg0 [--dry-run] [--version X.X.X] [--method detect] \ |
|
|
|
[--prefix ~/.local] [--rsh ssh] [user@host] |
|
|
|
--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 | standalone] |
|
|
|
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. |
|
|
|
- standalone installs a standalone release archive into ~/.local |
|
|
|
Add ~/.local/bin to your \$PATH to use it. |
|
|
|
--prefix <dir> |
|
|
|
Sets the prefix used by standalone 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 |
|
|
|
--rsh <bin> |
|
|
|
Specifies the remote shell for remote installation. Defaults to ssh. |
|
|
|
- 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 standalone |
|
|
|
release into ~/.local |
|
|
|
- For macOS it will install the Homebrew package. |
|
|
|
- If Homebrew is not installed it will install the latest standalone release |
|
|
|
into ~/.local |
|
|
|
- For FreeBSD, it will install the npm package with yarn or npm. |
|
|
|
- If ran on an architecture with no releases, it will install the |
|
|
|
npm package with yarn or npm. |
|
|
|
- We only have releases for amd64 and arm64 presently. |
|
|
|
- The npm package builds the native modules on postinstall. |
|
|
|
It will cache all downloaded assets into ~/.cache/code-server |
|
