Deno.run

run

• run(opt: RunOptions): Process

• • 定义在 lib.deno.ns.d.ts:2758

  派生新的子进程。 RunOptions 必须包含 opt.cmd，即程序参数数组，其中第一个参数是二进制文件路径。

  Spawns new subprocess. RunOptions must contain at a minimum the opt.cmd, an array of program arguments, the first of which is the binary.

  子进程使用与父进程相同的工作目录，除非指定了 opt.cwd。

  Subprocess uses same working directory as parent process unless opt.cwd is specified.

  子进程的环境变量可以使用 opt.env 来设置。

  Environmental variables for subprocess can be specified using opt.env mapping.

  默认情况下，子进程继承父进程的 stdio。要更改这些值，可以分别指定opt.stdout、opt.stderr、opt.stdin

  • 可以将其设置为 ProcessStdio 或打开文件的 rid。

  By default subprocess inherits stdio of parent process. To change that opt.stdout, opt.stderr and opt.stdin can be specified independently - they can be set to either ProcessStdio or rid of open file.

  返回派生子进程的详细信息。

  Details of the spawned process are returned.
