npm install --force 和 npm install --legacy-peer-deps 有什么区别？

Question

我正在尝试使用

npm install

为项目安装node_modules。但失败了。

错误日志：

日志建议使用

npm install --force

或

npm install --legacy-peer-deps

我想了解

npm install --force

和

npm install --legacy-peer-deps

之间的基本区别。

另外，如果

--force

的性能优于

--legacy-peer-deeps

或反之亦然，那么更优选使用哪一个？

任何建议/指示都非常值得赞赏。谢谢！

Answer 1

两者的区别如下

--legacy-peer-deps

：安装时忽略所有对等依赖项，采用 npm 版本 4 到版本 6 的风格

--strict-peer-deps:

遇到任何冲突的对等依赖项时会失败并中止安装过程。默认情况下，npm 只会因根项目的直接依赖项引起的 PeerDependency 冲突而崩溃。

--forces :

将强制 npm 获取远程资源，即使磁盘上存在本地副本也是如此。
