有没有人遇到同样的问题?如果有，那么解决方案是什么？

Answer 1

我在使用npm@7.13.0时遇到了同样的错误，并能够通过降级到npm@7.5.4或运行npm update --force命令来修复它。

Answer 2

尝试：

npm i --legacy-peer-deps

Answer 3

这肯定是npm 7.*.*出了问题..我试过npm i --legacy-peer-deps，它对我很管用。

然而，它不应该是这样的，依赖关系应该在最新的稳定版本中处理。

以下是它可能导致的原因的详细推理：

What does npm install --legacy-peer-deps do exactly? When is it recommended / What's a potential use case?
