# Building Zed
How to build Zed from source for the first time.
## Prerequisites
- Be added to the GitHub organization
- Be added to the Vercel team
## Process
Expect this to take 30min to an hour! Some of these steps will take quite a while based on your connection speed, and how long your first build will be.
1. Install the [GitHub CLI](https://cli.github.com/):
- `brew install gh`
1. Clone the `zed` repo
- `gh repo clone zed-industries/zed`
1. Install Xcode from the macOS App Store
1. Install Xcode command line tools
- `xcode-select --install`
- If xcode-select --print-path prints /Library/Developer/CommandLineTools… run `sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer.`
1. Install [Postgres](https://postgresapp.com)
1. Install rust/rustup
- `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`
1. Install the wasm toolchain
- `rustup target add wasm32-wasi`
1. Install Livekit & Foreman
- `brew install livekit`
- `brew install foreman`
1. Generate an GitHub API Key
- Go to https://github.com/settings/tokens and Generate new token
- GitHub currently provides two kinds of tokens:
- Classic Tokens, where only `repo` (Full control of private repositories) OAuth scope has to be selected
Unfortunately, unselecting `repo` scope and selecting every its inner scope instead does not allow the token users to read from private repositories
- (not applicable) Fine-grained Tokens, at the moment of writing, did not allow any kind of access of non-owned private repos
- Keep the token in the browser tab/editor for the next two steps
1. (Optional but reccomended) Add your GITHUB_TOKEN to your `.zshrc` or `.bashrc` like this: `export GITHUB_TOKEN=yourGithubAPIToken`
1. Ensure the Zed.dev website is checked out in a sibling directory and install it's dependencies:
```
cd ..
git clone https://github.com/zed-industries/zed.dev
cd zed.dev && npm install
npm install -g vercel
```
1. Link your zed.dev project to Vercel
- `vercel link`
- Select the `zed-industries` team. If you don't have this get someone on the team to add you to it.
- Select the `zed.dev` project
1. Run `vercel pull` to pull down the environment variables and project info from Vercel
1. Open Postgres.app
1. From `./path/to/zed/`:
- Run:
- `GITHUB_TOKEN={yourGithubAPIToken} script/bootstrap`
- Replace `{yourGithubAPIToken}` with the API token you generated above.
- You don't need to include the GITHUB_TOKEN if you exported it above.
- Consider removing the token (if it's fine for you to recreate such tokens during occasional migrations) or store this token somewhere safe (like your Zed 1Password vault).
- If you get:
- ```bash
Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!
Please create a new installation in /opt/homebrew using one of the
"Alternative Installs" from:
https://docs.brew.sh/Installation
```
- In that case try:
- `/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"`
- If Homebrew is not in your PATH:
- Replace `{username}` with your home folder name (usually your login name)
- `echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/{username}/.zprofile`
- `eval "$(/opt/homebrew/bin/brew shellenv)"`
1. To run the Zed app:
- If you are working on zed:
- `cargo run`
- If you are just using the latest version, but not working on zed:
- `cargo run --release`
- If you need to run the collaboration server locally:
- `script/zed-local`
## Troubleshooting
### `error: failed to run custom build command for gpui v0.1.0 (/Users/path/to/zed)`
- Try `xcode-select --switch /Applications/Xcode.app/Contents/Developer`
### `xcrun: error: unable to find utility "metal", not a developer tool or in PATH`
### Seeding errors during `script/bootstrap` runs
```
seeding database...
thread 'main' panicked at 'failed to deserialize github user from 'https://api.github.com/orgs/zed-industries/teams/staff/members': reqwest::Error { kind: Decode, source: Error("invalid type: map, expected a sequence", line: 1, column: 0) }', crates/collab/src/bin/seed.rs:111:10
```
Wrong permissions for `GITHUB_TOKEN` token used, the token needs to be able to read from private repos.
For Classic GitHub Tokens, that required OAuth scope `repo` (seacrh the scope name above for more details)
Same command
`sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer`
### If you experience errors that mention some dependency is using unstable features
Try `cargo clean` and `cargo build`
