## Apple M1
If you are using ARM64 Node.js, which can be checked using:
Prebuilt libvips binaries are provided for macOS on ARM64 (since sharp v0.28.0).
```sh
node -p "process.arch === 'arm64'"
```
then libvips must currently be installed via Homebrew before installing sharp.
```sh
brew install vips
```
During `npm install` sharp will be built locally,
which requires Xcode and Python - see
[building from source](#building-from-source).
When this new ARM64 CPU is made freely available
to open source projects via a CI service
then prebuilt binaries can be provided.
then prebuilt sharp binaries can also be provided.

## Known conflicts
### Electron and Linux
The prebuilt binaries provided by Electron for Linux depend on many shared system libraries.
One of these, `libgobject-2.0.so`,
is known to conflict with the statically-linked binaries provided by sharp
and the following error can occur:
```
basic_string::_S_construct null not valid
```
To workaround this, set the `LD_PRELOAD` environment variable before the `electron` binary is run.
```sh
LD_PRELOAD=node_modules/sharp/vendor/8.10.5/lib/libvips.so.42 electron script.js
```
### Canvas and Windows
The prebuilt binaries provided by `canvas` for Windows depend on the unmaintained GTK 2, last updated in 2011.
