[英]How do I switch from npm to yarn in my project?
I'm having an issue trying to switch to yarn from npm inside my project.我在尝试从项目中的 npm 切换到纱线时遇到问题。 I tried downloading yarn and I'm still getting npm to start my project.
我尝试下载纱线,但我仍然得到 npm 来启动我的项目。 I need to switch because a project I'm working on needs it to be yarn so I can add a maven frontend plugin to tie my backend and frontend to gather for deployment.
我需要切换,因为我正在处理的项目需要它是纱线,所以我可以添加一个 maven 前端插件来绑定我的后端和前端以进行部署。

Full simple step-by-step answer:完整的简单一步一步的答案:
npm i -g yarn
npm i -g yarn
yarn
command yarn
命令的目录yarn.lock
file, now delete package-lock.json
* Note
yarn.lock
文件,现在删除package-lock.json
* Note
package.json
file replace in "scripts"
all npm
commands for yarn
** Note
package.json
文件中,在"scripts"
中替换所有npm
yarn
的命令** Note
yarn dev
or whatever command u use for running a yarn script => DONEyarn dev
或你用来运行 yarn 脚本的任何命令=> DONE * Note:
it is important you don't delete it before yarn
command (as some people suggest) it can break things, for example your yarn
command will not even work and it will throw error: * Note:
重要的是你不要在yarn
命令之前删除它(正如一些人建议的那样)它会破坏一些东西,例如你的yarn
命令甚至不会工作,它会抛出错误:
Error: ENOENT: no such file or directory, open './package-lock.json'
** Note:
If you used ** Note:
如果您使用
"preinstall": "npx npm-force-resolutions",
you can remove it, yarn is taking "resolutions"
by default without a need for force:)你可以删除它,yarn 默认情况下会采取
"resolutions"
,而不需要强制:)
It's quite simple;这很简单; follow those instructions:
遵循这些说明:
Yarn
is installed on your machine globally, else use npm install -g yarn
to install it.Yarn
是否已全局安装在您的机器上,否则使用npm install -g yarn
安装它。yarn
on your CLI; yarn
; Yarn
can consume the same package.json
format as npm, and can install any package from the npm registry. Yarn
can consume the same package.json
format as npm, and can install any package from the npm registry. For more details, check the official yarn doc .有关更多详细信息,请查看官方 yarn 文档。
You need not to do anything to switch from npm to yarn as long as yarn is installed in your Computer.只要您的计算机中安装了 yarn,您无需执行任何操作即可从 npm 切换到 yarn。 Also to install packages using yarn, you should run the command
yarn
rather than yarn install
which is equivalent to npm install
.同样要使用 yarn 安装包,你应该运行命令
yarn
而不是yarn install
,它等同于npm install
。 Because yarn is nothing stand alone library.因为 yarn 不是一个独立的库。 Yarn is only a new CLI client that fetches modules from the npm registry.
Yarn 只是一个新的 CLI 客户端,它从 npm 注册表中获取模块。 Nothing about the registry itself will change — you'll still be able to fetch and publish packages as normal.
注册表本身不会发生任何变化——您仍然可以正常获取和发布包。
