简介：

我最近完成了MERN堆栈课程，并去将我的构建推送到Heroku，但遇到了上面的错误。我最初认为这是visual studio权限错误，所以我用提升的权限运行vs代码。然而，这并没有奏效。

我尝试过，但没有成功：

1. 将nodejs脚本构建包添加到我的部署中
2. 修改我的package.json以包含引擎，该引擎选择要运行的node.js版本
3. 在脚本部分将.js扩展添加到服务器的末尾，认为这可能有一个简单的问题
4. 仔细检查我的本地实例是否正常工作(确实如此(
5. 立即把我的电脑扔出窗外(感觉很好，但仍然无法工作(

请参阅此链接，了解如何检查文件的正确权限以及如何设置权限(在Windows 7上使用git bash更新文件权限(

Answer 1

sh: 1: react-scripts: Permission denied

所以这是一个权限问题。转到包含react-scripts的正确路径并执行chmod +x react-scripts将解决此问题。

Answer 2

我看了你的GitHub repo，它似乎是你的.gitignore文件中的一个简单的拼写错误：

node_module/ config/default.json

这应该是：

node_modules/ config/default.json

注意node_modules文件夹的名称，因此快速修复方法是编辑.gitignore文件并输入wright名称，然后运行以下操作：

• git rm -r --cached node_modules
• delete node_modules in root directory as well in client/
• git commit -am 'ignore node_modules'最后推送您的更改，这应该会修复错误

Answer 3

检查您的软件包.json=>React脚本-->

步骤＝1＝＝>quot；反应脚本"："(change_current_version("；

例如："；反应脚本"："1.0.1"；更改===>quot；反应脚本"："3.4.3"；

步骤＝2＝＝>install=>npm i

步骤＝3＝＝>npm启动
