由于这个“远程：sh：1：react-scripts：权限被拒绝错误”，正在努力将我的反应项目部署到 heroku

Question

I know that this answer has been asked in the past but I could not find a solution that pertains to my case. I've tried reinstalling my node_modules and my package-lock files, I've made sure that my.gitignore file properly excludes node_modules from the build. I'm not entirely sure what's going wrong when I try to deploy. I've been working on this for a couple of days, trying to diagnose the issue to no avail. So I figured that I'd try here. I am using a server-client setup wherein I have separate package files for my server-side code and my client-side code. Here are the package files, my gitignore file and the error log from the heroku build session:

Edit: I forgot to mention that it appears that my react scripts file has full permissions:

Answer 1

hey have you found the answer yet? I tried:

if (process.env.NODE_ENV === "production"){

app.use(express.static(path.join(__dirname,"client", "build")))

app.get("*", (req, res) => {
    res.sendFile(path.join(__dirname,"client", "build", "index.html"));
});
}

and i have to npm install react-scripts in the server package.json file. Also you have to put the "proxy": "http://localhost:5000" at the last curly brace in client package.json file. That proxy is the server port. It works for me!
