【问题描述】：

我尝试在我正在接管开发的节点/反应应用程序上运行 npm install 时遇到错误。

我不想在全球范围内安装任何软件包。我在运行 Big Sur 的 M1 Macbook Pro 上。我用 Homebrew 重新安装了 node 和 npm。我还尝试删除 package-lock.json 文件，清理 npm 缓存，并将 .npmignore 文件添加到目录中，正如其他一些帖子所建议的那样；这些都不起作用。

这是我运行npm install时的输出

MacBook-Pro-2 frontend % npm install

我尝试运行npm install --legacy-peer-deps，这会导致稍有不同的错误：

【问题讨论】：

你能发布 package.json 吗？

标签： node.js reactjs npm node-modules

【解决方案1】：

我解决了自己的问题。我认为这是一个常见的错误信息，有很多潜在的解决方案；以下是我尝试过的两件事，为我解决了这个问题：

确保您已安装 postgresql（如果您的项目包括一个 postgresql 数据库，如我的）。在带有自制软件的 Mac 上，只需运行 brew install postgresql。
我还将我的 Node.js 版本降级为最新的长期支持版本（之前我使用的是开发版本）。在撰写本文时，LTS 版本是 14.7。

进行这些更改后，我能够正确安装和启动我的网站。
