Rust & Wasm 初始设置

Question

我遵循本教程使用rust创建web组装应用程序，但当我尝试使用node运行捆绑的web组装代码时(在添加任何自己的代码之前，并完全遵循教程(

$ npm run start

webpack.config

const CopyWebpackPlugin = require("copy-webpack-plugin");
const path = require('path');
module.exports = {
entry: "./bootstrap.js",
output: {
path: path.resolve(__dirname, "dist"),
filename: "bootstrap.js",
},
mode: "development",
plugins: [
new CopyWebpackPlugin(['index.html'])
],
};

package.json依赖项

"dependencies": {
"minimist": "^1.2.5",
"wasm-game-of-life": "file:../pkg"
},
"devDependencies": {
"copy-webpack-plugin": "^6.1.0",
"hello-wasm-pack": "^0.1.0",
"webpack-cli": "^3.1.0",
"webpack-dev-server": "^3.11.0"
}

我和以前一样重新编写了教程，得到了同样的结果。我认为这是我的npm设置的问题，但我不确定。

Answer 1

由于安全警报，当我从教程文件中指定的版本更新复制webpack插件时，我遇到了类似的错误。配置参数的格式同时发生了变化，所以我不得不更改它们以匹配。

本教程将"copy-webpack-plugin": "^5.0.3"和我升级为"copy-webpack-plugin": "^6.0.3"，在webpack.config.js中我必须更改

new CopyPlugin([
path.resolve(__dirname, "static")
]),

new CopyPlugin({
patterns: [
path.resolve(__dirname, "static")
]
}),

我不熟悉webpack或复制webpack插件，除了通过你正在学习的相同的rust-wasm教程，所以使用这个建议的风险自负；我只能说它似乎起了作用。

Answer 2

我在尝试从同一教程运行npm run start时遇到了类似的错误

我的错误是没有Node.js的LTS版本，而是最新版本。

• 我按照以下步骤完全删除了我的Node.js
• 并安装了安全的LTS
