Process is not defined in dependency package - reactjs

Question

Recently i had to create a new project in react using typescript / webpack. I have included the package "sass-loader" which has a dependency of chalk (1.1.3).
When I try to npm start, the console shows this error:
Uncaught ReferenceError: process is not defined
at Object../node_modules/chalk/index.js (main.js:62661)
at __webpack_require__ (main.js:228732)

I don't know if this could be a problem with this package or maybe is my webpack configuration... I'm new in webpack.
Here is my webpack conf:
{
mode: "development",
output: {
publicPath: "/",
},
entry: "./src/index.tsx",
module: {
rules: [
{
test: /\.(ts|js)x?$/i,
exclude: /node_modules/,
use: {
loader: "babel-loader",
options: {
presets: [
"#babel/preset-env",
"#babel/preset-react",
"#babel/preset-typescript",
],
},
},
},
{
test: /\.s[ac]ss$/i,
use: [
// Creates `style` nodes from JS strings
"style-loader",
// Translates CSS into CommonJS
{
loader: 'css-loader',
options: {
modules: {
localIdentName: 'styles_[local]_[hash:base64:5]'
}
},
},
// Compiles Sass to CSS
"sass-loader",
],
},
{
test: /\.css$/i,
use: [
// Creates `style` nodes from JS strings
"style-loader",
// Translates CSS into CommonJS
{
loader: 'css-loader',
options: {
modules: {
localIdentName: 'styles_[local]_[hash:base64:5]'
}
},
}
],
},
],
},
resolve: {
extensions: [".tsx", ".ts", ".js", ".jsx"],
alias: {
'#': '/src',
},
},
plugins: [
new Dotenv(),
new HtmlWebpackPlugin({
template: "public/index.html",
}),
new webpack.HotModuleReplacementPlugin(),
new ForkTsCheckerWebpackPlugin({
async: false,
}),
new ESLintPlugin({
extensions: ["js", "jsx", "ts", "tsx"],
})
],
devtool: "inline-source-map",
devServer: {
contentBase: path.join(__dirname, "build"),
historyApiFallback: true,
port: 4000,
open: false,
hot: true,
stats: 'errors-only'
},
}
Thanks in advance.
