Node.js 从另一个文件夹启动Persevere，而不是安装在中

我使用“npm安装persevere示例wiki”安装了Perserver，如这里所述。 从文件夹节点_modules/persevere example wiki启动服务器确实可以按指定方式工作。这是我请求的服务器日志

$ pwd
PROJECT_ROOT/node_modules/persevere-example-wiki
$ node index.js 
Listening on port 8282
persevere>createContext { id: 'Example',
  content: 'this is a test\n\n   and some other test',
  createdBy: 'admin',
  status: 'published',
  lastModifiedBy: 'qwe123' }
createContext public not found
error writing [object Object]TypeError: first argument must be a string or Buffer

但有几件事我不明白： 尽管我提供了正确的数据库凭据，数据库服务器中不会保存任何内容，但我输入到应用程序中的所有数据都只会以纯文本JSON文件的形式保存在“node_modules/persevere example wiki/data”文件夹中

如何从与node_模块/persevere示例wiki不同的文件夹启动persevere？我确信有一种方法可以配置路径，我想知道如何配置路径。我尝试将local.json复制到祖父母文件夹，并尝试从那里开始，但出现了更多错误：

$ node node_modules/persevere-example-wiki/index.js 

fs.js:427
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

现在，Persevere框架本身似乎过于复杂——或者可能只是文档问题。无论如何，有一个非常复杂的例子似乎不是一个好主意。通常，我更喜欢从较小的示例中构建。

使用

NODE\u PATH

环境变量添加

PROJECT\u ROOT/NODE\u modules/persevere示例wiki

作为搜索的默认目录：

   export NODE_PATH=$PROJECT_ROOT/node_modules/persevere-example-wiki
