JavaScript babel"TypeError:无法读取null的属性'bindings'"试图转运时 [英] JavaScript babel "TypeError: Cannot read property 'bindings' of null" when trying to transpile
问题描述
据我了解,使用PhpStorm,当我修改JavaScript源文件时,我有一个文件监视程序( babel ),该文件监视程序会做一些魔术,并将这些文件稍微转换一下后放在另一个文件夹中(dist
),以便 gulp 可以编译"所有内容,并且可以运行该应用程序.但是每当我修改文件而不是发生魔术时,我都会得到
Using PhpStorm, as I understand it, when I modify a JavaScript source file, I have this filewatcher (babel) that will do some kind of magic and places these files a little transformed in another folder (dist
) so that gulp can "compile" everything and the application can be run. But whenever I modify a file instead of the magic happening I get a
"TypeError:无法读取null的属性'bindings'" **
"TypeError: Cannot read property 'bindings' of null"**
我不明白为什么.
-
我的老师告诉我修改配置,以便它是babel.cmd而不是babel,因为我在Windows上,但这没用.
My teacher told me to modify the configuration so that it's babel.cmd and not babel because I'm on Windows, but that didn't work.
目前,我几乎已卸载并重新安装了所有内容,并且所有内容都达到了我认为的最新版本.
I pretty much uninstalled and re-installed everything at this point and everything is up to the latest version i believe.
我试图将.babelrc
文件中的预设设置为"@babel/preset-env"
,但这也不起作用.
I tried to set the preset in my .babelrc
file to "@babel/preset-env"
but that didn't work either.
{
"presets": ["@babel/preset-env"]
}

错误的详细信息
我真的不明白这个绑定"属性指的是什么,我应该对此进行更改,我没有在任何称为绑定的属性中进行编码.
Detail of the error
I don't really understand what this "bindings" property refers to and what i'm supposed to change about it, I didn't code in any property called bindings..

推荐答案
这是由于6和6之间的babel依赖项不匹配引起的. 7.您目前似乎已经安装了这两者.
This is caused by a mismatch of babel dependencies between 6 & 7. You currently seem to have both installed.
尝试从package.json
中的依赖项中删除babel-core
,babel-polyfill
和babel-preset-env
.
Try removing babel-core
, babel-polyfill
and babel-preset-env
from your dependencies in package.json
.
如果需要babel-polyfill
,则应该安装版本7软件包,该软件包已重命名为@babel/polyfill
.
If you need babel-polyfill
then you should install the version 7 package instead, which has been renamed to @babel/polyfill
.
