path

问题 I have a problem with a script I wrote. I'm just trying to run an executable (I took arduino.exe as an example). However, I either get a FileNotFoundError: [WinError 2] or a non-zero exit status (depending on Shell=True is off or on , respectively). The code of my entire script is simple: import subprocess subprocess.run("C:\Program Files (x86)\Arduino\arduino.exe",shell=True,check=True) I am aware that Shell=True poses a security risk, but have found no other way to solve the path not found

问题 I can't think of any algorithm that would find the longest path, that is smaller or equal to some x variable. With Dijkstra's algorithm I can easily get longest path, however I'm not sure if I can use it in my problem. 回答1: Dijkstra's algorithm will give you the shortest path, not the longest one. Finding the longest (simple) path is NP-Hard. Since your problem can be degenerated into the longest path problem (take x equal to the sum of all edge weights, which is an upper bound on the length

问题 I have made a script to open Spotify with wine: #!/bin/bash DIR="/home/jorgsk/.wine/drive_c/Program Files/Spotify/" cd "$DIR" wine spotify.exe 2>/dev/null I'm passing "$DIR" to cd with quotes because of the whitespace in "Program Files"; if I don't have the quotes "/home/jorgsk/.wine/drive_c/Programs" will be considered as the argument to cd, which obviously will result in an error message. Spotify starts fine if I launch the above script from its local directory (/home/jorgsk/bin) with .

问题 In Java for some reason the Ellipse2D.Double uses the parameters (height, width, x, y) where as when I create a RectF in Android the parameters are (left, top, right, bottom) so I'm a bit confused on adjusting to the differences. If a create an Ellipse in Java and use the following: //Ellipse2D.Double(height, width, x, y) x = 100; y = 120; centerX = getWidth() / 2; centerY = getHeight() / 2; //Ellipse2D.Double(100, 120, (centerX - 100) * 2, (centerY - 120) * 2); new Ellipse2D.Double(x, y,

问题 I am developing a website on php, I have installed wamp on my personal computer and my website files are in the www folder of wamp. now considering www as my root folder i have a template folder in the root folder and header.inc.html file in the template folder. when I try to include this header.inc.html file in any other php file using an absolute path include('/template/header.inc.html'); it gives me error "Failed to open stream: No such file or directory", but when I create a simple html

问题 I am wondering if it's possible to display full file path using the assert macro? I cannot specify full file path in compilation command, is there still a way to do it? My debug environment is linux/g++ 回答1: You can add the following macro option into your compilation line (Can be easily modify for your environment) %.o: %.cpp $(CC) $(CFLAGS) -D__ABSFILE__='"$(realpath $<)"' -c $< -o $@ then you just have to this to have your full path: #include <stdio.h> int main() { printf(__ABSFILE__); //

问题 I have a C++ program test.cpp and I want to link two .lib files to it(fhlib.lib and gc_lib.lib).I have the .lib files in the same folder as my .cpp program. I'm on Windows 7. What I have tried so far is the following: g++ -o main main.cpp -L/Users\Documents\Visual Studio 2015\Projects\My Project -lfhlib But I get an No such file or directory error. I'm sure the path is correct because I copied it from Properties->Location. But I had do delete the "C:\", because it was not compiling. EDIT: I

问题 My problem is that I have a number of directories I have to look into programmatically, in Java. These directories all have the same pattern: d:\a\b\c\??_????\d\ I cannot find a way to do this smartly. Any FileFilter (I use WildcardFileFilter) will need a base directory to look into, as they only works with listFiles(), yet in my case there is not base directory as my paths are absolute. I've unsuccessfully tried a few tricks from the Web and then I'm stuck. Your help will be greatly

问题 I am installing Homebrew on my Mac in order to install Macvim. After installing Homebrew, I am prompted to run brew doctor, which in turn generates a number of warnings. I have resolved several of these but am stuck on two: Warning: Enthought Python was found in your PATH. This can cause build problems, as this software installs its own copies of iconv and libxml2 into directories that are picked up by other build systems. I'm not sure if I should simply ignore this or look for a way to

问题 I am trying to add external cpp files as linked resources to an eclipse CDT project. I have managed to have relative paths for these cpp files in the eclipse project (files), but these are automatically expanded into absolute paths in the generated makefiles. We use the makefiles in a continuous integration system, where these absolute paths are not acceptable. I have tried to set up these paths to be relative to build variables, environment variables and even linux system variables, without
