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，请您建议可能的错误。

我正在使用命令

npm install --save realm

从网上-https://realm.io/docs/javascript/latest/

错误：

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

我已尝试安装

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

谢谢你

这是我的日志

    npm install --save realm

Answer 1

1）使用以下命令首次检查节点版本

节点-v
v10。16

如果版本与10.16不匹配。0，然后使用下面的链接安装节点

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

并安装节点10.16。0

使用下面的命令安装领域

npm安装--保存领域

域安装成功。！！！

Answer 2

感谢@Ashwin Mothilal，我必须回到节点的稳定版本（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。希望这有帮助

1-已卸载的节点。js完全来自我的机器。（Windows）遵循此链接-[如何从Windows中完全删除node.js（别忘了重新启动电脑）

2-从以下位置下载并安装稳定版本（8.11.3 LTS）：[https://nodejs.org/en/][1]

3-重新启动计算机。

4-现在检查节点版本(

5-在您的项目中删除所有节点_模块-rm-rf节点_模块/npm安装链接-[如何清理package.json中未包含的包的节点_模块文件夹？

6-然后做-

7-现在安装领域。

npm install --save realm

这已成功地将领域添加到我的项目中。

注意：当我得到这个错误，我已经张贴在我的实际问题，它建议我安装'node-pre-gyp'。我试图安装

  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，所以在执行上述步骤之前，我已经删除了“node pre gyp”。如果您已经安装了上述任何一个，您可以删除它们，因为这不是必需的。

希望这能有所帮助。R
