npm install the exact package version specified in package.json

由 那年仲夏 提交于 2019-11-29 02:53:35
Currently, If I run npm install , it installs the updated version of already installed packages. How can I install the exact version as specified in the package.json file? That behavior is really driven by the one specifying the versions in the package.json. If the version number looks like "1.0.0", without any other symbols, the exact version (1.0.0) should be installed. So what you could do is simply modify the package.json and run a npm install then. Be sure to clear out the node_modules directory before you do that. https://docs.npmjs.com/files/package.json#dependencies Dale Jefferson By

Why wouldn't I use npm to install yarn?

问题 In the blog post announcing yarn (an alternative npm client) they say, "The easiest way to get started is to run npm install -g yarn ". But if you go to the "install yarn" page in their docs, "npm install yarn" isn't listed on any of the platform-specific installation pages, and it's only offered as the third of three options on the "Alternatives" page. Furthermore when you npm install yarn it prints a deprecation warning, "It is recommended to install Yarn using the native installation

How do I deal with installing peer dependencies in Angular CLI?

由 旧时模样 提交于 2019-11-28 16:36:14
问题 I've found myself in an almost endless cycle of errors when trying to update my Angular CLI and NPM. Every time I update, I am met with WARN messages telling me to install peer dependencies (see below), but each time I install a dependency, I am met with more WARN messages. Is there a better way of handling this situation or does it seriously take hours? npm WARN @angular/animations@5.2.1 requires a peer of @angular/core@5.2.1 but none is installed. You must install peer dependencies yourself

问题 What is the difference between npm install and npm run build ? I have noticed in my project that sometimes npm starts failing when npm install is performed, but, upon running npm run build , it works just fine. How does the inner workings of these two targets namely install and run build differ? 回答1: npm install installs dependencies into the node_modules/ directory, for the node project you're working on. You can call install on another node.js project (module), to install it as a dependency

Recently I've made a switch to Node v.6, and It started creating more and more problems with running normal builds grunt/gulp/webpack For example: $ gulp [14:02:20] Local gulp not found in ~/_Other/angular-2-ts/angular2-seed [14:02:20] Try running: npm install gulp while gulp and all other plugins and modules are installed (and even re-installed via rm -rf node_modules ) in /node_modules folder. Most of those errors have line like (node:42) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version. with 42 as

What is the difference between “npm install” and “npm ci”?

由 折月煮酒 提交于 2019-11-28 13:43:08
问题 I'm working with continuous integration and discovered the npm ci command. I can't figure what the advantages are of using this command for my workflow. Is it faster? Does it make the test harder, okay, and after? 回答1: From the npm docs: In short, the main differences between using npm install and npm ci are: The project must have an existing package-lock.json or npm-shrinkwrap.json. If dependencies in the package lock do not match those in package.json, npm ci will exit with an error,

When running npm install -g ionic I get the following error: FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory Is there a way to globally increase the node.js memory limit?

base 64 encode and decode a string in angular (2+)

由 北慕城南 提交于 2019-11-28 06:41:10
How to encode or decode a string in angular 2 with base64 ??? My front-end tool is Angular 2. I had a password string, before passing it to API I need to base64 encode. Since in service base64 encoded string will be decoded. So I am looking for some base64 encode/decode library for Angular2/Typescript and some options. Thanks!!! Use the btoa() function to encode: console.log(btoa("password")); // cGFzc3dvcmQ= To decode, you can use the atob() function: console.log(atob("cGFzc3dvcmQ=")); // password Use btoa("yourstring") more info: https://developer.mozilla.org/en/docs/Web/API/WindowBase64
