## node-canvas 依赖说明 / About Canvas Dependence
By default, binaries for macOS, Linux and Windows will be downloaded. If you want to build from source, use `npm install --build-from-source` and see the **Compiling** section below.
The minimum version of Node.js required is **6.0.0**.
### Compiling
If you don't have a supported OS or processor architecture, or you use `--build-from-source`, the module will be compiled on your system. This requires several dependencies, including Cairo and Pango.
For detailed installation information, see the [wiki](https://github.com/Automattic/node-canvas/wiki/_pages). One-line installation instructions for common OSes are below. Note that libgif/giflib, librsvg and libjpeg are optional and only required if you need GIF, SVG and JPEG support, respectively. Cairo v1.10.0 or later is required.
| OS | Command |
| ------- | --------------------------------------------------------------------------------------------------------------- |
| OS X | Using [Homebrew](https://brew.sh/):
`brew install pkg-config cairo pango libpng jpeg giflib librsvg pixman` |
| Ubuntu | `sudo apt-get install build-essential libcairo2-dev libpango1.0-dev libjpeg-dev libgif-dev librsvg2-dev` |
| Fedora | `sudo yum install gcc-c++ cairo-devel pango-devel libjpeg-turbo-devel giflib-devel` |
| Solaris | `pkgin install cairo pango pkg-config xproto renderproto kbproto xextproto` |
| OpenBSD | `doas pkg_add cairo pango png jpeg giflib` |
| Windows | See the [wiki](https://github.com/Automattic/node-canvas/wiki/Installation:-Windows) |
| Others | See the [wiki](https://github.com/Automattic/node-canvas/wiki) |
**Mac OS X v10.11+:** If you have recently updated to Mac OS X v10.11+ and are experiencing trouble when compiling, run the following command: `xcode-select --install`. Read more about the problem [on Stack Overflow](http://stackoverflow.com/a/32929012/148072).
If you have xcode 10.0 or higher installed, in order to build from source you need NPM 6.4.1 or higher.
