iOS NativeScript 权限错误生成 EACCES

Question

我正在尝试设置 nativescript 开发环境。我按照官方文档中描述的步骤进行操作。 Link

之后我使用

创建了一个新项目

tns create my-first-app --template tns-template-hello-world-ng

然后我使用以下命令添加了 iOS 和 Android 平台

tns platform add ios
tns platform add android

执行时

tns run android

一切正常。模拟器正在启动并打开应用程序。

然而，当运行

tns run ios

我收到以下错误：

Searching for Devices...
spawn EACCES

我已经尝试更改应用程序目录的权限

sudo chmod -R a+rwx /[AppFolder]

正在执行

sudo tns run ios

没有解决问题

编辑 2017-10-5 回应 Nikolai Tsonevs 的回答：

执行以下没有解决问题：

tns platform remove ios
npm cache clean --force
tns platform add ios
tns run ios

我的节点版本是：v8.4.0 我的 npm 版本是：5.4.2

我还执行了以下命令与您分享输出（假设 Nikolai 的意思是 ios 而不是 android）：

tns platform remove ios
tns platform add ios --log trace > out.txt

这是输出：

编辑：2017-10-06 作为尼古拉回答的结果，我做了以下事情：

npm i -g node-gyp
sudo gem install xcodeproj
brew install mono
brew install gradle (was not installed as well)
brew install cocoapods
brew link -overwrite cocoapods (brew was complaining about link issues)

之后我再次删除了 iOS 并添加了它。这也不起作用。

我执行了以下操作以获取更多信息：

tns run ios --log trace > run.txt

这里是相关的输出：

Answer 1

你能尝试用

清理 npm 缓存吗

npm cache clean
删除平台 tns platform remove ios
再次添加 tns platform add ios
使用tns run ios

如果问题依然存在，能不能把tns platform remove ios的平台去掉再重新添加 tns platform add android --log trace > out.txt 然后您可以共享 out.txt 文件的输出，这有助于进一步调查问题。此外，请提供有关您的 node 和 npm 版本的信息。

编辑：

嗨@Anton 由于提供的日志，我发现有几个错误，这些错误是在添加平台时抛出的。第一个是找不到 node-gyp 插件。要解决此问题，您有两种选择。

第一个是使用 npm install node-gyp --g 手动安装插件。如果这不能解决问题，我建议使用 npm cache clear 清理 npm 缓存并降级到最新的 LTS 节点版本 6.11.4。

关于另外两个错误，请确保您已安装 xcodeproj 和 cocoapods。如果在以下情况下没有安装它们：sudo gem install xcodeproj sudo gem install cocoapods

Answer 2

感谢Nikolay的大力帮助，我终于解决了这个问题。

NativeScript 节点模块上的权限设置不正确，因此我执行了以下操作：

chmod -R +x /usr/local/lib/node_modules/nativescript/

iOS NativeScript 权限错误生成 EACCES

iOS NativeScript permission Error spawn EACCES

ios

nativescript
