Python 复制网页包插件配置问题
在electron.js应用程序中,我试图根据以下指示从node.js调用并执行python脚本: 我得到了这个错误:Python 复制网页包插件配置问题,python,node.js,webpack,child-process,copy-webpack-plugin,Python,Node.js,Webpack,Child Process,Copy Webpack Plugin,在electron.js应用程序中,我试图根据以下指示从node.js调用并执行python脚本: 我得到了这个错误: error:python3: can't open file '/home/marco/webMatters/electronMatters /PythonConnection/.webpack/main/scripts/factorial.py': [Errno 2] No such file or directory Closed 注释选项时部分: execFil

注释选项时
部分:
execFile('./scripts/factorial.py',
[parseInt(msg)],
//{ cwd: './scripts',
//env: '/home/marco/anaconda3/bin/python3'
//},
(error, stdout, stderr) => {
if (error) {
throw error;
}
console.log(stdout);
}
);
我也犯了同样的错误
以下是此处发现的迹象:
我修改代码如下:
const { spawn } = require('child_process');
let nb = parseInt(msg);
function runScript() {
return spawn ('python3', [
"-u",
path.join(__dirname, './scripts/factorial.py'),
nb,
]);
}
const subprocess = runScript();
subprocess.stdout.on('data', (data) => {
console.log(`data:${data}`);
});
subprocess.stderr.on('data', (data) => {
console.log(`error:${data}`);
});
subprocess.stderr.on('close', () => {
console.log("Closed");
});
我得到这个错误:
error:python3: can't open file '/home/marco/webMatters/electronMatters
/PythonConnection/.webpack/main/scripts/factorial.py': [Errno 2] No
such file or directory
Closed
下面是这里的提示:我将/tools/webpack/webpack.plugins.js修改为:
const CopyPlugin = require("copy-webpack-plugin");
module.exports = [
new ForkTsCheckerWebpackPlugin(),
new webpack.ExternalsPlugin('commonjs', [
'electron'
]),
new CopyPlugin({
patterns: [
{ from: "src/scripts/", to: ".webpack/main/script/" },
],
}),
];
对我来说,这似乎是尊重标准的,但我得到了一条很长的错误信息:

这似乎更进一步,但仍有一些问题需要解决
节点版本:v14.5.0
操作系统:ubuntu18.04桌面版
如何解决这个问题?
期待您的帮助看来您的问题在于您使用的是webpack<5和复制的webpack plugin 7,它们不兼容 只要做:
npm install copy-webpack-plugin@6 --save-dev
来修复它。谢谢你@Grègory L。我用组合解决了这个问题:“复制网页包插件”:“6”,“网页包”:“4”
