创建-反应-应用程序不生成package.lock文件

Question

今天我做了一个反应网络项目。因此，它的工作，fine.And，然后，我创建了另一个反应项目。但在这一点上没有任何package.lock文件。所以我使用npm install手动创建了它。但是之后，当我使用npm i react-particles-js命令将依赖项添加到该项目时，我得到了这样一个错误消息。

另外，当我手动创建package.lock文件时，我会得到这条日志消息。

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.

，所以问题是为什么我没有自动获得package.lock文件，为什么不能正确安装依赖项？

Answer 1

这可能是因为app现在正在使用纱线。

使用yarn

• Instead of npm i react-particles-js代替npm install使用yarn add react-particle-js

您可以确认是否有yarn.lock文件
