EPERM，不允许操作

Question

我正在使用钛和 genymotion 作为 android 模拟器。我收到以下错误：-

[ERROR] 触发“执行后”事件时出错 [错误] 错误：EPERM，不允许操作 'C:\Users\sudatta.titanium\analytics_session.json' 在 fs.openSync (fs.js:439:18) 在 fs.writeFileSync (fs.js:978:15) 在 c:\Users\sudatta\AppData\Roaming\npm\node_modules\titanium\node_modules\node-appc\lib\analytics.js:192:7 在 c:\Users\sudatta\AppData\Roaming\npm\node_modules\titanium\node_modules\node-appc\node_modules\async\lib\async.js 完成后（c:\Users\sudatta\AppData\Roaming\npm\node_modules\titanium\node_modules\node-appc\node_modules\async\lib\as 在 c:\Users\sudatta\AppData\Roaming\npm\node_modules\titanium\node_modules\node-appc\node_modules\async\lib\async.js 在 c:\Users\sudatta\AppData\Roaming\npm\node_modules\titanium\node_modules\node-appc\node_modules\async\lib\async.js 在 c:\Users\sudatta\AppData\Roaming\npm\node_modules\titanium\node_modules\node-appc\lib\analytics.js:113:5 在 getOSInfo (c:\Users\sudatta\AppData\Roaming\npm\node_modules\titanium\node_modules\node-appc\lib\environ.js:205:3

我检查了几篇关于 genymotion 错误的文章，但我的错误似乎与此无关。任何人都知道为什么突然开始出现此错误。 我有文件analytics_session.json 的权限。 谢谢。

Answer 1

也许您应该结束 Nodejs 任务，然后再次尝试构建。发生这种情况是因为 EventIO 仍然附加到早期的构建过程。

Answer 2

您正在尝试写入一个您没有写入权限的文件。既然您似乎有一个文件句柄，那么您肯定是以读取模式而不是写入模式打开它的。
