How to use the import-cwd.silent function in import-cwd

return new Promise((resolve, reject) => {
      const sass = importCwd.silent('node-sass') || importCwd.silent('sass')

          file: this.id,
          data: `@import "${injectFile.replace(/\\/g, '\\\\')}";` + code,
          indentedSyntax: /\.sass$/.test(this.id),
          sourceMap: this.sourceMap,
          importer: [
            (url, importer, done) => {
              if (!moduleRe.test(url)) return done({ file: url })
