// The Node team wants to deprecate `process.bind(...)`.

// However, we need the 'uv' binding for errname support.
|
|
// This is a defensive wrapper around it so `execa` will not fail entirely if it stops working someday.
|
|

|
|
// If this ever stops working. See: https://github.com/sindresorhus/execa/issues/31#issuecomment-215939939 for another possible solution.
