Node v14 compiled against M1 (arm64) Running Cypress under Rosetta 2

Once the installation is complete, run node -p 'process.arch' to show arm圆4.

Use nvm to install node.js, for example nvm install v14.

Launch the original Terminal/iTerm (non-Rosetta).

Node v12 compiled against Rosetta 2 (圆4) Install arm64 Node.js

Once the installation is complete, run node -p 'process.arch' to show 圆4.

Use nvm to install node.js, for example nvm install v12.

Launch the Terminal/iTerm Rosetta (created above).

We can install an 圆4 and arm64 within nvm to make switching between those easy. The Node Version Manager (nvm) is a "version manager for node.js, designed to be installed per-user, and invoked per-shell". Set iTerm Rosetta to "Open using Rosetta", by checking the box after right clicking.

Right-click on the Terminal/iTerm Rosetta app in Applications.

In the Applications folder, copy Terminal/iTerm and rename it to Terminal/iTerm Rosetta.To run Terminal/iTerm under Rosetta 2 without the arch -x86_64 prefix it's best to set Terminal/iTerm to always run under Rosetta 2.

Adapting iTerm/Terminal to run under Rosetta 2 A version of Node compiled without a prefix will yield arm64 from process.arch. Thus running node and process.arch inside of the node process will yield 圆4 for a version of Node compiled using the arch -x86_64 prefix.

Install Rosetta 2Īs a prerequisite to compiling Cypress on an ARM-based Mac, Rosetta 2 can be installed in a single command.įirst, manually install Rosetta 2 (accepting the license agreement): softwareupdate -install-rosetta -agree-to-licenseĪfter installation, any program/process may be run under Rosetta 2 prefixing it with arch -x86_64įurthermore, you can verify what architecture a given program/process was compiled under if they make that information available.įor example, Node provides an arch attribute on its process variable. Therefore, running npm install cypress will install the Intel-based package until these challenges are resolved. For these reasons, Cypress is not currently released for the ARM-based architectures and will require Intel emulation for some time. The ProblemĪt the moment, Cypress cannot be compiled under the ARM-based architecture of new Mac computers and Continuous Integration (CI) providers do not currently offer M1 instances.

Naturally, developers would like all of their current software to run as-is on this new and insanely fast architecture.Īs it goes with most leaps in technology, software may take a bit of time to catch up with the latest hardware improvements.Ĭurrently, the way to run Cypress on Apple M1 ARM chip is by using Intel emulation with Rosetta 2, Apple's translation layer. Apple's latest ARM-based M1 chip has begun to make it into the hands of developers across the world.
