问题描述
我正在尝试创建我的React项目的生产版本,但它选择了错误的配置。
I'm trying to create a production build of my React project, but it picks the wrong configuration.
在开发版本中,我使用的是HMR(热模块更换)。这是在.babelrc中,在 env>下配置的。发展>插件
。
添加额外节点 env>生产
似乎被忽略了。它仍在使用HMR的开发配置,这会导致错误:
In the development version I'm using HMR (Hot Module Replacement). This is configured in .babelrc, under env > development > plugins
.When adding an extra node env > production
it seems to be ignored. It's still using the development configuration with HMR, which causes an error:
我当然检查了这些信息,但一切似乎都是正确的。
当我从.babelrc的开发配置中删除HMR插件时,它可以工作,证明它确实使用了开发配置而不是生产。
这是我的档案:
Of course I've checked that information, but everything seems right.When I removed the HMR plugin from .babelrc's development config, it works, proving it is indeed using the development config instead of production.Here's my files:
package.json
{
"name": "myproject",
"main": "index.js",
"scripts": {
"serve": "cross-env NODE_ENV=development webpack-dev-server --content-base bin/ --devtool eval --progress --colors --hot --inline",
"deploy": "cross-env NODE_ENV=production BABEL_ENV=production webpack -p --config webpack.production.config.js"
}
//dependencies omitted in this example
}
.babelrc
{
"presets": ["react", "es2015", "stage-0"],
"plugins": [
["transform-decorators-legacy"]
],
"env": {
"development": {
"plugins": [
["react-transform", {
"transforms": [{
"transform": "react-transform-hmr",
"imports": ["react"],
"locals": ["module"]
}]
}]
]
},
"production": {
"plugins": []
}
}
}
当你可以在 package.json>中看到脚本>部署
,我甚至明确地将BABEL_ENV设置为'production'。
As you can see in package.json > scripts > deploy
, I'm even explicitly setting the BABEL_ENV to 'production'.
为什么会这样?如何确保生成构建忽略HMR插件?
Why is this happening? How do I make sure the production build ignores the HMR plugins?
顺便说一下,搜索通常会导致,这是一个没有明确解决方案的长线程。
By the way, searching often leads to issue #5 on the React-transform-HMR Github page, which is a long thread without a clear solution.

推荐答案
唯一对我有用的是,我写道 -
The only thing that worked for me, is that I wrote -
process.env.NODE_ENV = 'production';
。
