我们最近将Meteor + React应用程序升级为使用Meteor 1.7。以前是Meteor 1.6。我们正在使用Babel进行转译。如迁移文档所建议，我们已将Babel升级到7。对于Babel 7，建议我们使用babel-preset-env代替babel-preset-es2015。由于我们进行了所有这些更改，因此在执行meteor run时遇到以下错误。
使用ecmascript处理文件时（对于目标web.browser）：
C:\Users\kashif.nazar\AppData\Local\.meteor\packages\ecmascript\0.11.1\plugin.compile-ecmascript.os\npm\node_modules\meteor\babel-compiler\node_modules\@babel\traverse\lib\scope\index.js:869:13:
Cannot read property 'bindings' of null
请注意，meteor npm install运行正常。
package.json文件中的依赖项如下。

.babelsrc具有以下几行。
{
"presets": ["env"]
}
配置中是否缺少导致错误的内容？
