            How to copy the output of pexpect to a file
            Asked 2022-Mar-28 at 09:23

            What I expect are:

            1. the output of pexpect can be displayed in the terminal in real time, so that I can see the real-time progress of the script execution.
            2. the output of pexpect can be copied to a file, so that the log can be automatically managed.

            I know how to display the results on the terminal and how to redirect the results to a file, but I don’t know how to implement these two features at the same time.

            This looks to be an active issue relating to poetry. See here - Issue #4085. Some suggest a workaround by downgrading poetry-core down to 1.0.4.

            There is an active PR to fix the issue.

            No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'
            Asked 2022-Mar-13 at 16:13

            I am trying to build an app from a python file (Mac OS) using the py2app extension. I have a folder with the python file and the "setup.py" file.

            • I first tested the app by running python setup.py py2app -A in the terminal and the dist and build folder are successfully created and the app works when launched.
            • Now when I try to build it non-locally by running the command python setup.py py2app in the terminal, there are various "WARNING: ImportERROR" messages while building and finally a error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib' error.

              How can I fix this? I've tried to delete anaconda fully as I don't use it but it seems to still want to run through it. Additionally, I have tried to run the build command using a virtual environment but I end up having even more import errors.

            The error error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib' was caused by py2app trying to build the program bundle using a non-existent interpreter. This means that even if you try to uninstall a manager like Anaconda, it still has option logs somewhere on your mac.

            The fix:

            1. Open the terminal and type the command type -a python.

            Best way to manage y/n and password prompts through a Python script
            Asked 2022-Feb-15 at 19:02

            I am creating a Python script to install AUR packages but can't figure out how to detect yes/no and root password prompts.

            So far what I have managed is to get rid of yes/no prompts using yes command, like this.

            Detect the password prompt: The password prompt appears mainly after makepkg enters in fakeroot. IDK how to detect that and supply the password from the script. There is no pattern actually. Some package evoke 1 y/n prompt while some prompt more than 1.

            There is a pattern. An y/n prompt is shown when:

            • makepkg invokes pacman to install build dependencies (for the -s option);
            • makepkg invokes pacman to install the freshly built package (for the -i option);
            • makepkg invokes pacman to remove the build dependencies (for the -r option).
            • makepkg invokes pacman to...

            In all cases, if makepkg is given the --noconfirm option, it will pass that to pacman as well.

            Enter actual password: Actually, I want to enter password through a GUI. So, basically, I want user to input password in a text box that I will create using Tkinter.

            The password prompt, if any, is shown by sudo. Sudo supports running external "askpass" tools through the SUDO_ASKPASS environment variable.

            Write or install a program that shows the password prompt and outputs the password to stdout (e.g. ssh-askpass or zenity would do), then set the SUDO_ASKPASS environment variable to the program's path:

            applaunchservices appears to be Apple-only:

            Simple package for registering an app with apple Launch Services to handle UTI and URL. See Apple documentations for details.

            I suspect you don't need that, either. Did you create your requirements.txt from a pip freeze? There's likely a bunch of stuff in there you don't need.

            I suggest you review that file and remove anything you aren't directly depending on. pip will find transitive dependencies (dependencies your dependencies depend on) and install them automatically.

            Prune that file, commit, and redeploy.

            When I check the dump, session matches b'First_line:\r\n', but p.stdin.write doesn't move the pexpect cursor forward to look for "Second_line:", as what happens with send() or sendline().

            May I suggest a simpler way, using PopenSpawn? The docs state that it "provides an interface like pexpect.spawn interface (sic) using subprocess.Popen":
