create-react-app 不生成 package.lock 文件

Question

今天我在做一个 React Web 项目。所以它起作用了 fine.And 然后我创建了另一个反应项目。但是那里没有任何 package.lock 文件。所以我使用 npm install 手动创建了它。但是在那之后，当我使用 npm i react-particles-js 命令向该项目添加依赖项时，我收到了这样的错误消息。

npm ERR! code ERESOLVE

另外，当我手动创建 package.lock 文件时，我收到此日志消息。

npm WARN old lockfile
npm WARN old lockfile The package-lock.json file was created with an old version of npm,
npm WARN old lockfile so supplemental metadata must be fetched from the registry.
npm WARN old lockfile
npm WARN old lockfile This is a one-time fix-up, please be patient...

所以问题是为什么我没有自动获取 package.lock 文件以及为什么我不能正确安装依赖项？

Answer 1

可能是creat-react-app现在使用yarn了

而不是 npm install 使用 yarn
而不是 npm i react-particles-js 使用 yarn add react-particle-js

您可以确认您是否有 yarn.lock 文件
