我不明白,我在做什么错。我安装(激活)研磨机:
$ pub global activate grinder
然后,我创建一个简单的工具/grind.dart:
import "dart:io";
import "package:grinder/grinder.dart";
main(args) => grind(args);
@Task("Build")
build() {
Process.run("webdev build", []);
}
但是然后Process.run()失败,没有这样的文件或目录错误:
$ grind build
ProcessException: No such file or directory
Command: webdev build

即使webdev构建确实可以正常工作(在路径中)?:
$ webdev build
Creating build script
...
这是什么问题?我该如何解决?还是有一种方法可以直接从Dart代码中以编程方式调用webdev构建?
答案 0 :(得分:1)
可执行文件不得包含参数。
改用:
Process.run("webdev", ["build"]);
