问题 I know, with Ubuntu, you can set default values for environment variables in /etc/environment ; I do not see that file in Alpine linux. Is there a different location for setting system-wide defaults? 回答1: It seems that /etc/profile is the best place I could find.

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: Is there a way to get a vector with the name of all functions that one could use in R? Hi I would like to get from R the list of functions loaded in the environment. I know ls() that gives the list of objects loaded. But some objects are not functions. I would like to clean my env from the functions but not from the other objects (matrices, array etc) that contain some of my result that dont want to lose. Any

问题 I have written a (very simple) little Python script, and I want to be able to distribute it to friends who have no idea what Python is, nor anything about Windows cmd scripts. So, fundamentally I need to install Python on their systems, followed by installing the required libraries for my script, followed by my script (and appropriate start-up links in their desktop). I have no interest in creating some sophisticated install program. So, I have written a very simple, trivial little cmd script

问题 I am trying to use environment variables in a react app created on WSL. I cannot access the variables from my app. Here is what I did: Create a .env file at the root folder of my react app (within a client folder of a Rails app) Create a variable: REACT_APP_API_URL=http://localhost:3000/api/v1/ Log the variable in my console: console.log(process.env.REACT_APP_API_URL) Restarted the server I keep getting an undefined variable.
