Question

在学习Meteor（基于Node.js构建）

的同时，设置一个简单的开发环境

从一个简单的测试开始，在env.sh中我只有：

导出CUSTOM_VAR =“某些值”

然后在app.js中，我有：

if (Meteor.isClient) {
  console.log(Meteor.settings);
}

if (Meteor.isServer) {
  console.log('Meteor Settings:');
  console.log(Meteor.settings);

  console.log('');
  console.log('Environment Variables:');
  console.log(process.env);
  console.log(process.env.CUSTOM_VAR);
}

我得到的结果似乎是来自其他一些env.sh的变量，并且CUSTOM_VAR未定义。

一旦它达到了“某种价值”，但不会再次（并且我已经做了所有事情）

这里有完整的结果：

这条线特别有趣：

为什么Python文件夹中的路径？我想也许几年前我在python中建立了一个全球环境？我是这个环境的新手。如何解决这个问题？

环境变量undefined
