如何通过 Yarn 安装带有本地路径的包?找不到包 [英] How to install package with local path by Yarn? It couldn't find package

问题描述

在我的 package.json 中，我通过其相对路径指向本地包 my-custom-i18n:

In my package.json I'm pointing local package my-custom-i18n by its relative path:

"dependencies": {
 "core-js": "^2.4.1",
 "my-custom-i18n": "./../MyProject.Shared/myproject-i18n",
 "rxjs": "5.0.0-beta.12",
 ...
}

npm install 正确安装包，但 yarn 有问题，根本找不到这个包:

npm install installs packages correctly, but yarn has problem with it and simply cannot find this package:

$ yarn
yarn install v0.15.1
info No lockfile found.
[1/4] Resolving packages...
error Couldn't find package "myproject-i18n" on the "npm" registry.
info Visit http://yarnpkg.com/en/docs/cli/install for documentation about this command.

我看到它在 npm 注册表中查找，此包不在该注册表中.

I see that it looks it on the npm registry, where this package doesn't live.

在本地包中使用 yarn 有什么变化吗?本地包是指由相对路径指向的包为 my-custom-i18n.

Is there any change to use yarn with local packages? By local packages I mean packages pointed by relative path as my-custom-i18n.

推荐答案

对于yarn版本<2.x

Yarn 需要前缀 file: 用于本地包.

对于相对路径:

yarn add file:./../your-project

对于绝对路径

yarn add file:/dev/your-project

对于您的示例，package.json 中的依赖项将声明如下:

For your example, dependency in package.json would be declared as follows:

 "my-custom-i18n": "file:./../MyProject.Shared/myproject-i18n",

这也适用于 Yarn 和 NPM.

This works both for Yarn and NPM as well.

它与 NPM 客户端不兼容，Yarn 团队意识到并声明支持此行为 - 参考GitHub 问题.

It is incompatibility with NPM client, Yarn team is aware and declared to support this behavior - reference on GitHub issue.

更新:

自 v0.21.0 发布以来，不需要 file: 前缀.参见 pull-request with fix 和 更改日志.

Since v0.21.0 release, file: prefix is not needed. See pull-request with fix and changelog.
