Yarn install Invariant Violation：应该有一个解决的参考

Question

我正在尝试在 Jenkins 2.150.1 上构建一个版本，但在安装 yarn 时遇到错误： Invariant Violation: should have a resolved reference

安装在我的本地机器上运行良好，配置相同。

有人知道我该如何解决这个问题吗？

发现这是由于 CI 服务器的 yarn 版本造成的。

在本地降级到版本 1.3.2 并且能够复制该问题。

升级到yarn 1.16，问题就消失了。

解决方案：升级yarn：

sh "curl --compressed -o- -L https://yarnpkg.com/install.sh | sh"
