Flutter Dart Process.run 未处理的异常：ProcessException：系统找不到指定的文件

Question

我正在尝试使用 dart 的

Process.run

运行命令行

这是我的代码

var result = await Process.run('axmldec', [ '-o','C:/test/output.xml'
      , 'C:/test/AndroidManifest.xml' ]);

认为问题是斜杠/所以我也尝试了这个

var result = await Process.run('axmldec', [ '-o','C:\\test\\output.xml'
      , 'C:\\test\\AndroidManifest.xml' ]);

尝试过 C: 和 D: 驱动器，但没有运气。我得到的错误是

Command: axmldec -o D:/test/output.xml D:/test/AndroidManifest.xml
#0      _ProcessImpl._start (dart:io-patch/process_patch.dart:390:33)
#1      Process.start (dart:io-patch/process_patch.dart:36:20)

#13     FilePickerCross.importMultipleFromStorage (package:file_picker_cross/file_picker_cross.dart)
<asynchronous suspension>

当我在命令行中运行相同的命令时，它可以正常工作。

Answer 1

我找到了解决方案。问题似乎是命令本身“axmldec”的路径

尽管在环境变量中进行了设置，但 dart 进程无法识别它。我使用了完整路径并且有效

var result = Process.run('c:\\tool\\axmldec.exe', [ '-o','D:\\test\\output.xml'
      , 'D:\\test\\AndroidManifest.xml' ]);

Answer 2

将

runInShell

标记为 true 可能会在运行命令（例如

flutter

commnad）时有所帮助。

Process.run(
  'flutter',
  [ 'create', 'example' ],
  runInShell: true,
  workingDirectory: directory,
);
