node.js - 构建 nodejs 失败，退出状态 126 - 权限被拒绝

Question

当我在 Linux 服务器中执行 npm start 时遇到问题。

显示错误，退出代码为 126，权限被拒绝。

我已经对 server.js 或者 demoTest 的整个文件夹执行了 chmod 777。

如何解决这个问题？

日志如下所示。

在运行 Nodejs 服务器和 Reactjs 客户端时，我遇到了同样的问题。这个过程对我有用，应该在受影响的目录中完成(我认为这对您来说是 demoTest):

1. 删除node_modules
2. 运行 npm install 以重新安装该目录的 package.json 中的依赖项

我相信当我将node_modules从主机复制到Ubuntu服务器而不是直接从服务器CLI运行安装时，这个问题就开始了。
