environment

问题 I'm very new to CompoundJS. I'm working on a sample application which accesses data in MongoDB. I'm wondering if there is any way to switch environment in CompoundJS as we do in Rails (RAILS_ENV = development/test/production). Any help would be appreciated. Thanks in advance. 回答1: As usual in nodejs you can use NODE_ENV variable (same as RAILS_ENV in ruby/rails): NODE_ENV=production node . Should work for compound (from the working dir of your compound project). 来源： https://stackoverflow.com

问题 I'm trying to test out creating virtual envs through conda create on OS X. It's my first real foray into virtual envs so I'm still wrapping my mind around how to tool them. My first test was $ conda create -p /users/me/anaconda/envs/envtest $ source activate /users/me/anaconda/envs/envtest But when I go to take it down via source deactivate , I get: Error: too many arguments. Some googling seems to indicate that there is some configuration in my .profile file that's affecting this but that

问题 MIT Scheme's (load ...) procedure apparently takes in an environment as a parameter. Is there any way I could "clone" the current environment and pass it there, so that I can isolate the file's environment from my own? (I've looked here but I haven't found anything...) 回答1: How about something like this ? (define (clone-env env) (let ((bindings (environment-bindings env))) (make-top-level-environment (map car bindings) (map cadr bindings)))) 1 ]=> (define foo 1) ;Value: foo 1 ]=> (eq? (the

问题 I have noticed that some of my environment variables are not being picked up by the JVM. In my .bash_profile I defined the following: IO_HOME='some_value' export IO_HOME and by doing in shell: echo $IO_HOME I get the correct result. But neither System.getProperties() nor System.getenv() is showing this variable being set. I tried both Java 6 and Java 7. Is there something I am missing? 回答1: Exporting environment to spawned processes is pretty stable; if System.getenv() is not including a

问题 Whats a bulletproof way to determine if I am running inside a vagrant machine? Guest OS is Debian Linux, though if there are indicators per-os that would be great to have documented as well. 回答1: AFAIK, there isn't a way outside of your own customizations. One idea that comes to mind is to touch a file that you then reference from your apps. Add something like config.vm.provision "shell", inline: "touch /etc/is_vagrant_vm" to the bottom of your Vagrantfile and base your conditionals around

问题 I'm using Dusk to do a simple login test. I created a .env.dusk file so that the test uses an alternate database and does not delete the data that was registered on the platform. Archive .env DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=laravel_dusk DB_USERNAME=root DB_PASSWORD=123456 Archive .env.dusk DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=laravel_dusk_test DB_USERNAME=root DB_PASSWORD=123456 LoginTest.php namespace Tests\Browser; use Tests

问题 When running some tests I came across the following issue. When using: private String printStandardDate(Date date) { return DateFormat.getDateTimeInstance( DateFormat.SHORT, DateFormat.SHORT).format(date); } I found this produced different formats of Date depending on the location the tests where run from. So locally in windows / eclipse I got a result: 04/02/12 18:18 but on the Linux box in America I get 2/4/12 6:18 PM This causes my Tests/Build to fail: expected:<[04/02/12 18:18]> but was:<

问题 I am following the RailsTutorial and have been creating a Users model with appropriate attrs and validations. I've run into this error and cannot see where the problem is. The project is configured using Rails5, thus models inheriting from ApplicationRecord should be correct: User.rb: class User < ApplicationRecord before_save { self.email = email.downcase } validates :name, presence: true, length: { maximum: 50 } VALID_EMAIL_REGEX = /\A([\w+\-].?)+@[a-z\d\-]+(\.[a-z]+)*\.[a-z]+\z/i validates

问题 I wrote a simple program in cuda-c and it works on eclipse nsight. This is source code: #include <iostream> #include <stdio.h> __global__ void add( int a,int b, int *c){ *c = a + b; } int main(void){ int c; int *dev_c; cudaMalloc((void**)&dev_c, sizeof(int)); add <<<1,1>>>(2,7,dev_c); cudaMemcpy(&c, dev_c, sizeof(int),cudaMemcpyDeviceToHost); printf("\n2+7= %d\n",c); cudaFree(dev_c); return 0; } Now I'm trying to use this code with Go language with cgo!!! So I wrote this new code: package

问题 I have a worker role in my hosted service. The worker is sending e-mail daily bases. But in the hosted service, there are 2 environment, Staging and Production. So my worker role sends e-mail 2 times everyday. I'd like to know how to detect if the worker is in stagning or production. Thanks in advance. 回答1: As per my question here, you'll see that there is no fast way of doing this. Also, unless you really know what you are doing, I strongly suggest you not do this . However, if you want to,
