// The Node team wants to deprecate `process.bind(...)`. |
|
// https://github.com/nodejs/node/pull/2768 |
|

|
// 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. |
