为什么我无法获得https://registry.yarnpkg.com的本地颁发者证书

Question

在运行unable to get local issuer certificate时，我碰巧得到了错误的yarn add <anything>。

昨天它很好，但是今天它突然发生了，我不记得做了什么具体的事情。

在运行yarn config set strict-ssl false之后，它再次工作，但这是非常可疑的。

我知道我的问题似乎是重复的，但事实并非如此。我一直在到处搜索，但它们似乎是在某些情况下出现的，比如在公司代理后面运行，或者设置一个新的服务器。我不是任何代理人的幕后黑手。

请你帮我看看我应该在哪里进一步调查，以了解真正的根源。

我在macOS蒙特利12.0.1

1. 检查您的.npmrc是否没有指定手动CA。
2. 检查您是否在公司代理后面。
3. 检查您的本地证书是否已损坏。
