dart - Process.run() : No such file or directory

Question

我不明白，我做错了什么。我安装(激活)研磨机:

$ pub global activate grinder

然后我创建了一个简单的工具/grind.dart:

import "dart:io";
import "package:grinder/grinder.dart";

main(args) => grind(args);

@Task("Build")
build() {
  Process.run("webdev build", []);
}

但是 Process.run() 失败了 No such file or directory 错误:

$ grind build
ProcessException: No such file or directory
  Command: webdev build

即使 webdev 构建工作正常(在路径中)？:

$ webdev build
Creating build script
...

这里有什么问题？我怎么能解决这个问题？或者有没有办法直接从 Dart 代码以编程方式调用 webdev 构建？

Answer 1

可执行文件不得包含参数。
改用:

Process.run("webdev", ["build"]);
