无法为我的 React Native App 安装 Realm

Question

我正在尝试为我的 React 本机应用程序安装 Realm，但出现以下错误，您能否提出可能的问题。

我正在使用命令

npm install --save realm

来自网络 - https://realm.io/docs/javascript/latest/

错误：

npm ERR! Failed at the realm@2.11.0 install script.

我已经尝试安装了

npm install -g node-pre-gyp

和

npm install -g node-gyp

还是不行。任何建议都会很有帮助

谢谢 回复

这是我的日志

    npm install --save realm

感谢@Ashwin Mothilal，我不得不回到稳定版本的 Node (v8.11.3)。我是怎么做到的。

花了一段时间才弄清楚整个过程，写下我执行的步骤。希望这会有所帮助

1 - 从我的机器上完全卸载 Node.js。 （视窗） 关注此链接 - [How to completely remove node.js from Windows （别忘了重启你的电脑）

2 - 从 - 下载并安装了稳定版本 (8.11.3 LTS) [https://nodejs.org/en/][1]

3 - 重启你的机器。

4 - 现在检查节点版本（>> node -v）。

5 - 在您的项目中删除所有 node_modules - rm -rf 节点模块/ npm 安装 关联 - [How to clean node_modules folder of packages that are not in package.json?

6 - 然后在您的项目中执行 - >>npm install。 这应该会安装所有必需的依赖项。

7 - 现在安装 Realm。

npm install --save realm

这已成功将 Realm 添加到我的项目中。

注意： 当我收到我在实际问题中发布的这个错误时，它建议我安装“node-pre-gyp”。 我尝试安装

  npm install --save node-pre-gyp --fallback-to-build
  npm install --save node-pre-gyp
  npm install -g node-pre-gyp 

这不起作用，所以在我执行上面提供的步骤之前，我已经删除了“node-pre-gyp”。如果您已经安装了上述任何一个，您可以将它们删除，因为它不是必需的。

希望这会有所帮助。 回复

1) 首先使用以下命令检查节点版本

节点-v
v10.16.0

如果版本与 10.16.0 不匹配，则使用以下链接安装节点

https://nodejs.org/en/download/

并安装节点 10.16.0

使用以下命令安装领域

npm install --save 领域

Realm 安装成功。！！！
