我使用react-native来开发Android应用程序。当应用程序运行时,我尝试从react-native开发人员菜单中选择Debug in Chrome,然后它应用程序崩溃,但在控制台中,我运行命令react-native start我看到并错误:

Launching Dev Tools...

Haven在堆栈和互联网上没有发现任何类似的问题。

我已经能够重现这个错误,并且它似乎是一个边缘情况,因为使用babel-polyfill版本6.16.0运行旧版本的React Native(0.22.x)。当前版本的React Native(0.40.0)和Babel Polyfill(6.20.0)不会出现此错误。我们认为它不相关,但我们正在运行节点7.2.0。

如果您无法更新您的环境,一个临时解决方法是编辑&#babel-polyfill / node_modules / core-js / modules / _typed-buffer.js'并修改该文件的第157和175行的缓冲区检查:

if(numberLength != byteLength)throw RangeError(WRONG_LENGTH);

如果您正在运行babel-polyfill 6.20.0,那么您的文件将在此处:

node_modules/core-js/modules/_typed-buffer.js

我们已经能够通过评论这个长度检查来让我们的开发环境工作,但需要注意,你可能不想让它投入生产。
