为什么Dart的“Process.start”当命令在Ubuntu终端工作时执行Ubuntu命令? [英] Why can't Dart's "Process.start" execute an Ubuntu command when the command works in Ubuntu terminal?
问题描述
我有命令我想和Dart联系。
命令是 sonar-runner
完美如果我在一个正常的Ubuntu终端运行它。这是因为我已经编辑了 .profile
文件中的 PATH
,因此它成为一个全局命令。
Process.start
代码,应该触发同样的事情: Process.run('sonar-runner',[]) {
stdout.write(result.stdout);
stderr.write(result.stderr);
});
我作为回应:
命令:sonar-runner
未处理的异常:
ProcessException:没有这样的文件或目录文件或目录
命令:sonar-runner
我猜这是一个Ubuntu配置的东西,因为我没有问题通过Dart以相同的方式运行 ping localhost
。
可能出错,第三方应用程序在作为新进程运行时找不到全局命令?
UPDATED - 解决方案已发现
我找到了我的问题的解决方案,如下所述:
对于我的具体情况, :
Process.run(bash,[ -c,sonar-runner])然后((result){
stdout.write(result.stdout);
stderr.write(result.stderr);
});
尝试此方法在正常的Ubuntu终端
:
Process.run('sonar-runner',[],runInShell:true).then((result){
stdout.write(result.stdout);
stderr.write(result.stderr );
});
I have command I would like to call with Dart.
The command is sonar-runner
which works perfectly if I run it in a normal Ubuntu terminal. This is because I have edited the PATH
in the .profile
file so it becomes a global command.
However, if I wrote a simple Process.start
code that should trigger the same thing:
Process.run('sonar-runner', []).then((result) {
stdout.write(result.stdout);
stderr.write(result.stderr);
});
I get as a response:
Uncaught Error: ProcessException: No such file or directory
Command: sonar-runner
Unhandled exception:
ProcessException: No such file or directory
Command: sonar-runner
I am guessing this is an Ubuntu configuration thing, as I have no problem running ping localhost
via Dart in the same way.
What could be wrong, so that a third party application cannot find global commands when running it as a new process?
UPDATED - SOLUTION WAS FOUND
I found the solution to my problem, as described here:
Set Environment variable using Process.start
For my specific case, this code worked:
Process.run("bash", ["-c", "sonar-runner"]).then((result) {
stdout.write(result.stdout);
stderr.write(result.stderr);
});
Try this approach run it in a normal Ubuntu terminal
:
Process.run('sonar-runner', [], runInShell: true).then((result) {
stdout.write(result.stdout);
stderr.write(result.stderr);
});
