启动项目时报错,如下:

node:internal/crypto/hash:71

this[kHandle] = new _Hash(algorithm, xofLen);

^

Error: error:0308010C:digital envelope routines::unsupported

at new Hash (node:internal/crypto/hash:71:19)

at Object.createHash (node:crypto:140:10)

{

opensslErrorStack: [ 'error:03000086:digital envelope routines::initialization error' ],

library: 'digital envelope routines',

reason: 'unsupported',

code: 'ERR_OSSL_EVP_UNSUPPORTED'

}

出现这个错误的原因是,node版本太高,跟openssl不匹配,node官方也说明: Node.js v17.x, v18.x, and v19.x use OpenSSL v3. 我的配置: node版本:node -v => v19.8.1 openssl版本:openssl version => LibreSSL 2.8.3

搜索了一番,在stackoverflow中搜到了解决方案。

方法一:

最简单 降低node版本,node<17以下即可,我这儿使用的nvm降低node到 v16.20.0,就可以正常启动项目了。

方法二:

设置node环境变量的参数: export NODE_OPTIONS=--openssl-legacy-provider windows端cmd:set NODE_OPTIONS=--openssl-legacy-provider windows端PowerShell: $env:NODE_OPTIONS = "--openssl-legacy-provider" 担心影响其他使用到node的程序,没有采用。

方法三:

跟上一种类似,只不过加入到启动项目的命令中 React:

"scripts": {

"start": "export SET NODE_OPTIONS=--openssl-legacy-provider && react-scripts start",

"build": "export SET NODE_OPTIONS=--openssl-legacy-provider && react-scripts build"

}

or

"scripts": {

"start": "react-scripts --openssl-legacy-provider start",

"build": "react-scripts --openssl-legacy-provider build",

}

Vue.js:

"scripts": {

"serve": "export NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve",

"build": "export NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service build",

"lint": "export NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service lint"

}

or

"scripts": {

"serve": "vue-cli-service --openssl-legacy-provider serve",

"build": "vue-cli-service --openssl-legacy-provider build",

"lint": "vue-cli-service --openssl-legacy-provider lint"

}

Angular:

"scripts": {

"start": "set NODE_OPTIONS=--openssl-legacy-provider && gulp buildDev && ng serve ",

"publish": "set NODE_OPTIONS=--openssl-legacy-provider && gulp build && ng build --prod",

}

方法四:

修改webpack版本,跟webpack中使用了md4哈希算法有关,在v5.61.0中使用了wasm实现的md4算法

https://github.com/webpack/webpack/releases/tag/v5.61.0https://github.com/webpack/webpack/issues/14532 or 如果webpack版本大于5.54,可以尝试一下修改experiments.futureDefaults: true和output.hashFunction: 'xxhash64',我没有尝试配置hashFunction:https://webpack.js.org/configuration/output/#outputhashfunction 但是更改webpack版本或者是修改output配置,也不一定就可以解决全部的问题,如果有别的node_modules包中,也使用了node的crypto.hash,那么还是会出问题,个人感觉还是降低node版本最划算。
