npm-scripts

问题 I would like to create a package.json build script that executes slightly different set of commands when run from Windows, Linux, Mac. The problem is that I cannot find a way to put it in package.json file that will run without problems at every system. Here is an example that I would like to have: "scripts" : { "build.windows" : "echo do windows specific stuff", "build.linux" : "echo do linux specific stuff", "build.mac" : "echo do mac specific stuff", "build" : "??????????????" <- what to

问题 In my package.json file I have the following scripts: "scripts": { "start": "npm run watch:all", "test": "echo \"Error: no test specified\" && exit 1", "lite": "lite-server", "sass": "node-sass -o sass/ css/", "watch:sass": "onchange 'sass/*.scss' -- npm run sass", "watch:all": "parallelshell 'npm run watch:sass' 'npm run lite'" } Whenever I run my code I got this error message: crs@1.0.0 start /home/hazem/crs > npm run watch:all > crs@1.0.0 watch:all /home/hazem/crs > parallelshell 'npm run

问题 Have recently put together a build tool with npm and package.json scripts, and I have a few echo commands to state which parts of the pipeline are currently running. For example (from my package.json ): { "scripts": { "clean": "rimraf a-directory/", "preclean": "echo \"\n[ Cleaning build directories ]\n\"" } } When I Bash: npm run clean it prints my echo message, and then cleans the appropriate directory. I'd like to change colour, font weight, background text colour to make these echo

问题 I have an issue when trying to pass arguments to an npm script with lerna . I have a node script that I want to run inside each package in the workspace. lerna docs suggests the following: { "scripts": { "my-script": "lerna exec -- node \\$LERNA_ROOT_PATH/scripts/my-script.js" } } so now, if I run in the root yarn run my-script it will run the script inside each package in the workspace. Sometimes, I need to scope the execution to a specific package. So running this from command line

问题 I have searched across different possible answers, but didn't find any appropriate addressing this specific error. I have mentioned the exact error string in the question title. This error started appearing when I installed fetch npm module in my ReactNative app. This error appears just at the time app is launched/loaded on my phone during development. Before installing fetch , my app was loading correctly on the phone. In windows CLI there is no such error that assist me to resolve the issue

问题 I am starting multiple npm tasks in parallel (using & , not just in sequence && ). Thus in package.json : "start": "npm run watch-blog & npm run watch-data & npm run server", And those sub-tasks are useful stuff to me like: "watch-blog" : "watchy -w _posts/**/* -- touch _pages/blog.md", Question: How can I all shut down all three tasks together? I noticed CTRL – C is only killing the last. (my watch-blog survives and keeps „touching“) Closing the terminal window doesn't help. Only killall

问题 I've got Webpack working with Babel and including the @babel/polyfill, yet IE11 is still throwing a SCRIPT438 error when trying to use .forEach on a NodeList . Here's my package.json { ...

问题 I want to reference my package version in a npm script so I can show current version in the app. Something like { "name": "bla", "version": "1.0.0", "author": "bla bla", "scripts": { "build": "node VERSION=<<package.version>> build/build.js" } } Is there a way to do this? 回答1: 1) Referencing package version in npm-scripts.
