可以 Python Subprocess.Popen handle/ignore Electron 应用程序启动时出现 ENOENT 错误并像在命令行中一样继续前进

Question

subprocess.open 抛出错误生成。/jre/bin/java ENOENT 异常

import subprocess
subprocess.run([r"C:\Users\<user>\AppData\Local\Programs\<some_dir>\<some_tool>.exe", "--args", "--remote-debugging-port=9000"])

也试过了，

subprocess.Popen([r"C:\Users\<user>\AppData\Local\Programs\<some_dir>\<some_tool>.exe", "--args", "--remote-debugging-port=9000"])

也尝试了Popen中的shell=True参数但没有解决

手动启动此应用程序不会导致任何问题。

不确定是什么导致了这个问题 - 我该如何解决？
当我运行 this from command 有类似的出现在控制台输出但没有出现阻塞对话框并且应用程序出现没有崩溃 - 我有什么办法可以

同样复制 python 的非崩溃行为。

命令行输出如下：

Answer 1

好的 - 所以 Electron Package 与它自己的 jre 版本捆绑在一起，这导致了问题，因为调用 exe 导致 JAVA 依赖项在系统默认情况下被查找jre 路径而不是与 Electron 应用程序捆绑在一起的路径。

解决方案 - 切换到应用程序的基本目录，然后启动它：

import subprocess, os
from subprocess import *
os.chdir(r"C:\app_dir")
subprocess.Popen(['app.exe'])

希望这对面临类似问题的人有所帮助。

可以 Python Subprocess.Popen handle/ignore Electron 应用程序启动时出现 ENOENT 错误并像在命令行中一样继续前进

Could Python Subprocess.Popen handle/ignore ENOENT error on Electron app launch and proceed ahead without fail as in command line

python

java

subprocess

electron

enoent
