Node.js 无法安装‘；文件’；从离子本机依赖相关？

因此，我对Ionic2非常熟悉，因此我遇到了一些新手问题=/我几乎搜索了所有内容，但找不到任何相关示例

我想做的是将一个文件写入设备的某个目录。我用的是Ionic2，我看到有一个“能满足我的需要”。但问题是我无法设置它

每当我执行

$npm安装--save@ionic native/file

时，我都会得到以下输出：

`project@0.0.1 D:\project\
+-- UNMET PEER DEPENDENCY @angular/core@2.2.1
+-- UNMET PEER DEPENDENCY @ionic-native/core@^3.1.0
+-- @ionic-native/file@3.2.1
-- UNMET PEER DEPENDENCY rxjs@5.0.0-beta.12`

`npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.1: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
npm WARN @ionic-native/file@3.2.1 requires a peer of @ionic-native/core@^3.1.0 but none was installed.
npm WARN @ionic-native/file@3.2.1 requires a peer of @angular/core@2.4.8 but none was installed.
npm WARN @ionic-native/file@3.2.1 requires a peer of rxjs@5.0.1 but none was installed.`

但每当我尝试使用npm安装来处理这些缺失的依赖项时，它总是一次又一次地给我同样的错误。我在这里迷路了。我已经尝试删除节点模块、缓存清理和安装，但仍然无法使文件正常工作

如果你能在这里帮助我，那就太好了。如果需要，我可以提供其他信息。干杯

---------以下是我在package.json中的依赖项

我试图在全新的项目中安装它，npm也抱怨@ionic native/core缺失。事实上，在安装@ionic native/file之前，您应该尝试分别安装它（和其他依赖项）

---

希望有帮助

我已经解决了这个问题

1：删除节点_模块，清理缓存并重新安装所有依赖项

rm -rf node_modules
npm cache clean
npm install

2：在我的问题上，我需要爱奥尼亚-native@core达到3.1.0或更高，能够使用离子-native@file. 所以我跑了

npm install --save @ionic-native/core

---

它得到了修复。

我试图安装未满足要求的angular、native和rxjs，但它一直在抱怨它=/它安装成功了吗？请尝试使用项目目录中的“npm ls”检查此项。您也可以尝试在其他订单中安装缺少的对等点好消息，我刚刚解决了这个问题。似乎我安装的“文件”版本需要-native@core版本为3.1.0或更高版本。
