How to resolve yarn error: Invalid violation: Expected a key

Question

我遇到了 yarn 的一些问题。因此通过自制软件（mac）卸载并重新安装它。现在运行上的任何纱线命令都会出现以下错误（即使在 yarn -v 上）

Invariant Violation: Expected a key
    at invariant (/usr/local/Cellar/yarn/1.22.15/libexec/lib/cli.js:2314:15)

因为 none 的 yarn 命令正在运行，所以也无法清除 yarn 缓存。如何解决这个问题？

运行今天遇到同样的问题，原来是 yarn.lock 文件中的空字符串引起的：

"@dockite/field@>= 1.1.14", "", "@dockite/field@^1.1.0","@dockite/field@^1.1.33":
