We use Google's zx to write scripts.

Its feature of automatically quoting all arguments works great in most circumstances, but sometimes we run into problems. For example, we want to issue the following command in our zx script:

eas build --local --platform ios --profile development

This command, when directly executed, works great:

await $`eas build --local --platform ios --profile development`

The arguments to eas build are dynamic, so we want to build the command:

const commandArgs = `${local ? ' --local' : ''}${platform ? ` --platform ${platform}` : ''}${profile ? ` --profile ${profile}` : ''}`;
...
await $`eas build ${command}`;

This leads to an error:

stderr: '/bin/bash: eas build --platform ios --local --profile development: command not found\n',

Second attempt was with the feature Array of Arguments:

const args = ['--local', '--profile development'];
if (platform) {
  args.push(`--platform ${platform}`);
}
...
await $`eas build ${args}`;

This time, the error is:

stdout: 'Unexpected arguments: --platform ios, --profile development\n' +

Any idea?

Turns out, we need to add arguments like '--profile development' as separate strings:

const args = ['--local', '--profile', 'development'];
if (platform) {
  args.push('--platform', platform);
}
...
await $`eas build ${args}`;
