【中文标题】iOS NativeScript 权限错误产生 EACCES【英文标题】：iOS NativeScript permission Error spawn EACCES 【发布时间】：2018-03-15 11:16:55 【问题描述】：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
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，应用程序打开。
但是，在运行时
tns run ios
我收到以下错误：
Searching for Devices...
spawn EACCES
我已经尝试更改应用目录的权限
sudo chmod -R a+rwx /[AppFolder]
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
我还执行了以下操作以与您分享输出（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 为了得到尼古拉的回答，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。这也没有用。
我执行了以下操作以获取更多信息：
tns run ios --log trace > run.txt
这是相关的输出：

【问题讨论】：
【参考方案1】：感谢 Nikolay 的大力帮助，我终于可以解决问题了。
在 NativeScript 节点模块上未正确设置的权限，因此我做了以下操作：
chmod -R +x /usr/local/lib/node_modules/nativescript/
【讨论】：
【参考方案2】：您可以尝试使用清理 npm 缓存吗
npm cache clean
用tns platform remove ios删除平台
用tns platform add ios再次添加
使用tns run ios启动应用程序
如果问题仍然存在，您能否再次删除带有tns platform remove ios 的平台并重新添加它
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，您有两个选择。
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。
关于其他两个错误，请确保您已安装 xcodeproj 和 cocoapods。如果在关注时不安装它们：sudo gem install xcodeprojsudo gem install cocoapods
【讨论】：
您好尼古拉，感谢您的帮助。我安装了丢失的软件包，但我又被卡住了。请参阅我的编辑以了解我已完成的日志/步骤。 感谢您的支持:)以上是关于iOS NativeScript 权限错误产生 EACCES的主要内容，如果未能解决你的问题，请参考以下文章
