问题
I have a local nexus server, I'd like yarn to look through it before going online, basically prefer-offline
yarn install --prefer-offline --cache-folder C:\folder\yarn-cache --preferred-cache-folder C:\folder\yarn-cache --non-interactive --no-lockfile --registry http://server/repository/npm-group
Yarn fails to find a dependency offline then fails to go online. I don't know if that can be fixed.
回答1:
- Create an npm (hosted) repository to use as your private registry. I believe you have already done this.
- Create an npm (proxy) repository pointing to your external repository of choice (https://registry.yarnpkg.com or https://registry.npmjs.org/).
- Create an npm (group) with your private registry on first position and the proxy registry on second position.
- Point yarn to your group repository:
yarn config set registry http://nexus.local/repository/npm-group/. If required by your Nexus configuration, authenticate yarn:yarn login.
Also be wary of yarn using any npm config you might have over it's own: https://github.com/yarnpkg/yarn/issues/4862

You can set a different registry in yarn by using the following command:
yarn config set registry <url-to-your-registry>
Verify that it has been set by typing the following command:
yarn config get registry
For a one-off change in registry you can use the variable YARN_REGISTRY like this:
YARN_REGISTRY="<url-to-your-registry>" yarn config get registry
or
YARN_REGISTRY="<url-to-your-registry>" yarn publish
