env

问题 I'm trying to enable the debug for my app but it looks like I don't have any feedback. The environment is set to local (in the .env file) and if I run php artisan env I get this Current application environment: local The debug config for my local env is set to true return [ 'debug' => true, Also if I set in my main config file (app.php inside the config folder) the debug = true I still have ho feedback that there is an error in the code. I only have an empty page if there is an error in the

问题 #!/usr/bin/env python I put that at the top of a script. I've seen that should make the script runnable from the command line without the need for python programname.py . Unless I'm misunderstanding I should be able to use programname.py as long as I have the above line at the top of the script. Is this correct? It isn't working for me I just get an error indicating that I would have to use python at the beginning of the 'call'. 回答1: Universal running of Python scripts You can pretty much

问题 In Grunt I used to use a plugin called env . That would allow me to define an environment in specific build. I had 3 builds. One was DEV which would use all the files split up individually. PROD would concat everything and RELEASE would concat and uglify. I'm looking to do the same in Gulp. I do see a preprocessor for Gulp but nothing to define environment. The question is. What can I do? Obviously I don't want to define all JS files all the time, and I don't want 3 different HTML pages with

问题 OS: Solaris Shell: Bash Shell Scenario: Input the commands separately: "env", "export" and "set" (without any arguments) and there will be a list of variables and values returned. My question: What's the difference among the returned values after inputting the three commands? 回答1: The env and export commands yield the same information, but not in the same format. And bash 's export produces a very radically different output from the output of ksh or (Bourne) shell's version. Note that set and

问题 I want to set a path environment variable in bash by C program. So I coded using 'setenv' function, But it was not the answer to solve. Could anybody suggest another way to solve this problem in C programming? I thought the other solution that the program read the profile file, then modify and save, but actually when I opened this file there's no string I wanted about PATH variable. 回答1: You can use setenv() and putenv() to set environment variables. But these will only be set for the given

问题 I have a C program that prints every environmental variable, whose name is given by stdin. It prints variables such as $PATH, $USER but it doesn't see the environmental variables that i defined myself in the Linux shell... For instance, in ~.bashrc I exported MYTEST=test_is_working, then I sourced the bashrc (source ~/.bashrc). I expected the program to return test_is_working with getenv but it doesn't. #include <QCoreApplication> #include <stdio.h> #include <stdlib.h> int main(int argc, char

问题 What are the advantages of placing data in a new .env in R?-speed, etc. For data such as time series, is an new .env analogous to a database? My question spans initally from downloading asset prices in R where it was suggested to place them into a new .env. Why is this so?

问题 I've set up Passenger in development (Mac OS X) and it works flawlessly. The only problem came later: now I have a custom GEM_HOME path and ImageMagick binaries installed in "/usr/local" . I can put them in one of the shell rc files that get sourced and this solves the environment variables for processes spawned from the console; but what about Passenger? The same application cannot find my gems when run this way. 回答1: I know of two solutions. The first (documented here) is essentially the

问题 I have a test script, e.g. "test.py", and I want to make it so that it executes with a particular environment variable set before the script begins: #!/usr/bin/env TEST=anything python print "Hello, world." Running this normally works as expected: $ python test.py Hello, world. However, if I run it as a program: $ chmod +x test.py $ ./test.py The string is never printed, instead the execution just stalls and "top" reports a process called "test.py" which is using 100% CPU. This only happens
