  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

这发生在我运行 npm i

我尝试删除 node_modules 并从头开始安装它，但没有帮助。

您知道如何解决它吗？

【问题讨论】：

标签： tensorflow npm terminal dependencies

【解决方案1】：

一些节点模块正在使用 node-gyp 来编译它们的代码。

在你的情况下，你使用的是 macos，所以你需要为 macos 安装编译工具。

您可以通过安装命令行工具来做到这一点。这可以通过执行轻松完成

xcode-select --install

或从应用商店安装xcode

安装好命令行工具后，重新运行npm install（之前会建议你删除node_module目录）

【讨论】：

我已经安装好了。但是，删除 xcode-select 并使用最新版本重新安装会有所帮助。
