我需要帮助，我刚刚执行了 npm uninstall react-bootstrap 然后又执行了 npm install react-bootstrap，但现在webpack无法再加载这个模块了。
我是这样启动webpack的：
/var/www/cloud/node_modules/.bin/webpack --config webpack.config.js --watch --display-error-details
以下是错误信息，它找不到 react-bootstrap 内的 package.json 文件：
ERROR in ./core/static/core/js/modules/dashboard/admin/Customer.js

这真的很奇怪，我的package.json看起来像：
{
"name": "cloud",
"version": "1.0.0",
"description": "hehe",
"main": "gulp.js",
"scripts": {
"dev": "webpack-dev-server --devtool eval --progress --colors --content-base build"

"style-loader": "^0.12.3",
"webpack": "^1.9.10",
"webpack-bundle-tracker": "0.0.51"
}
}
我的webpack配置：
var path = require("path");
var webpack = require('webpack');
var BundleTracker = require('webpack-bundle-tracker');
var bower_dir = __dirname + '/components/bower_components/';
var node_modules_dir = path.resolve(__dirname, 'node_modules');
module.exports = {
context: __dirname,
entry: {
app: [ './core/static/core/js/main.js', ],
vendor: ['react', 'react-router', 'react-bootstrap', 'react-google-recaptcha', 'react-spinkit'],
},
output: {
path: path.resolve('./static/bundles/'),
filename: 'bundle.js',
publicPath:''
},
externals: {
// require("jquery") is external and available
// on the global var jQuery
"jquery": "jQuery",
"utils": "utils"
},
plugins: [new BundleTracker({filename: './webpack-stats.json'}),
new webpack.optimize.CommonsChunkPlugin(/* chunkName= */"vendor", /* filename= */"vendor.bundle.js"),
/*new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery"
})*/],
module: {
loaders: [{ test: /\.jsx?$/, exclude: node_modules_dir, loaders: ['babel']}, // to transform JSX into JS
{ test: require.resolve("jquery"), loader: "imports?jQuery=jquery" },
{ test: /\.json$/, loader: "json" },
{ test: /\.css$/, loader: "style-loader!css-loader?root=." }],
},
resolve: {
modulesDirectories: ['node_modules', 'bower_components'],
extensions: ['', '.js', '.jsx']
},
};
此外，文件夹
react-bootstrap确实存在于我的node_modules中。我的目录结构如下：
webpack.config.js
node_modules
package.json
我完全迷失了......
react-bootstrap并在demo/index.js中执行了var bs = require('react-bootstrap');。对我来说很有效。 - Juho Vepsäläinenrm -r node_modules命令删除旧的包文件夹，然后再运行npm install命令，看是否仍会出现相同的问题。 - Austin Praynode_modules文件夹无效，请确保您也删除了package-lock.json文件，然后再尝试运行npm i。这对我来说解决了问题。 - Dominik
