[英]can not build react project due to webpack
我遇到了一个烦人的问题。 我正在尝试在其他事情上使用 web3 构建一个项目,但我遇到了一些我无法解决的编译错误:
Compiled with problems: X
ERROR in ../node_modules/cipher-base/index.js 3:16-43
Module not found: Error: Can't resolve 'stream' in 'C:\CAS\node_modules\cipher-base'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "stream": require.resolve("stream-browserify") }'
- install 'stream-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "stream": false }
我尝试了很多东西,但无法成功。 有人可以帮忙吗?
我设法让它工作
在网站根目录添加:webpack.config
包含:
module.exports = {
resolve: {
fallback: {
assert: require.resolve('assert'),
crypto: require.resolve('crypto-browserify'),
http: require.resolve('stream-http'),
https: require.resolve('https-browserify'),
os: require.resolve('os-browserify/browser'),
stream: require.resolve('stream-browserify'),
},
},
// Webpack 5 is enabled by default
// You can still use webpack 4 while upgrading to the latest version of Next.js by adding the "webpack5: false" flag
webpack5: false,
};
