subprocess

问题 I have created a Django REST framework project that I want to deploy on a server. I do not have admin access to the server, and so, the only way I found to ensure that all the project dependencies (such as Anaconda distribution) will be available on the server, is to create a docker image for my project , then create a corresponding container on the server, then run it from there. In my project, I have a python script (mymain.py) that gets called using subprocess.Popen(). This works fine

问题 I wrote a command-line tool to execute git pull for multiple git repos using python asyncio. It works fine if all repos have ssh password-less login setup. It also works fine if only 1 repo needs password input. When multiple repos require password input, it seems to get deadlock. My implementation is very simple. The main logic is utils.exec_async_tasks( utils.run_async(path, cmds) for path in repos.values()) where run_async creates and awaits a subprocess call, and exec_async_tasks runs all

问题 When executing subprocess.run() as given in the Python docs, I get a TypeError: >>> import subprocess >>> subprocess.run(["ls", "-l", "/dev/null"], capture_output=True) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.6/subprocess.py", line 403, in run with Popen(*popenargs, **kwargs) as process: TypeError: __init__() got an unexpected keyword argument 'capture_output' I am running Python 3.6.6: $ python3 --version Python 3.6.6 回答1: You inspected

问题 I am EE, trying to write a script to simplify file checks using Python. For some reason, our IT will not let me gain access to our SMTP server, and will only allow sending mail via mailx . So I've thought of running mailx from Python and send it, in the same way that it works in my console. Alas, it gives an exception.

问题 I'm using subprocess.Popen to launch several processes. The code is something like this: while flag > 0: flag = check_flag() c = MyClass(num_process=10) c.launch() MyClass if something like the following: MyClass(object) def __init__(self, num_process): self.num_process = num_process def launch(self): if self.check_something() < 10: for i in range(self.num_process): self.launch_subprocess() def launch_subprocess(self): subprocess.Popen(["nohup", "python", "/home/mypythonfile.py"], stdout=open

问题 I have a program written in python and used git command in it.. For some reason I don't want to use git-python or others instead of subprocess. But I'm currently stuck in getting git clone output. I've tried some code snippet. Some works fine with commands like ping 8.8.8.8 , but not the git clone . for example using thread def log_worker(stdout): while True: last = non_block_read(stdout).strip() if last != "": print(last) def non_block_read(output): fd = output.fileno() fl = fcntl.fcntl(fd,
