我很难找到这个错误，所以我发帖是为了帮助其他搜索类似错误的人。

我决定使用 eslint 和 Node.js 在 Atom 中的 Ubuntu 18.04 上建立一个新项目。

ESlint 本身安装并运行得很好eslint:recommended，但当我安装eslint-config-airbnb-base并更改配置以扩展时airbnb-base，我开始在 Atom 中收到错误，并且它不会解析我的文件。

Error while running ESLint: createRequire is not a function.

删除airbnb并依赖eslint-plugin-import会出现类似的错误：

Error while running ESLint: Failed to load plugin 'import' declared in '.eslintrc.yaml': createRequire is not a function.

但是，在命令行上运行 eslint 效果很好。

pip让我用一条消息升级:

You are using pip version 7.0.1, however version 7.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

所以我运行了该命令,我得到一个例外,即pip无法卸载旧版本,因为拒绝访问我的用户目录:

我正在使用以下代码计算从A点(右上角)到B点(左下角)的增量.但随着我们越来越接近B点,我的增量越来越远离预期的路径.图中的绿线是白点的预期路径.

        //double the steps to get more accurate calculations. 2 steps are calculated each frame
        var _stepT:Number = 2 * (dist * _speed); //_speed is in frames/pixel (something like 0.2)
