EPERM，不允许操作

Question

我使用钛和genymotion作为Android模拟器。我收到以下错误： -

[ERROR]触发“后执行”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     at done（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     at getOSInfo（c：\ Users \ sudatta \ AppData \ Roaming \ npm \ node_modules \ titanium \ node_modules \ node-appc \ lib \ environ.js：205：3

我已经查了几篇关于genymotion bug的文章，但我的错误似乎并不相关。任何人都知道为什么突然出现这个错误。 我拥有文件analytics_session.json的权限。 谢谢。

Answer 1

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

Answer 2

您正在尝试撰写一份您没有写入权限的文件。您似乎有一个文件句柄，您必须以读取模式打开它而不是写入。
