节点环境变量#

基于文件的配置

您可以为单个变量添加_FILE，以便在单独的文件中提供其配置。详情请参阅将敏感数据保存在单独文件中。

本页面列出了用于管理n8n中节点的环境变量配置选项，包括指定要加载或排除的节点、在代码节点中导入内置或外部模块，以及启用社区节点。

变量	类型	默认值	描述
`NODES_INCLUDE`	Array of strings	-	Specify which nodes to load.
`NODES_EXCLUDE`	Array of strings	-	Specify which nodes not to load. For example, to block nodes that can be a security risk if users aren't trustworthy: `NODES_EXCLUDE: "[\"n8n-nodes-base.executeCommand\", \"n8n-nodes-base.readWriteFile\"]"`
`NODE_FUNCTION_ALLOW_BUILTIN`	String	-	Permit users to import specific built-in modules in the Code node. Use * to allow all. n8n disables importing modules by default.
`NODE_FUNCTION_ALLOW_EXTERNAL`	String	-	Permit users to import specific external modules (from `n8n/node_modules`) in the Code node. n8n disables importing modules by default.
`NODES_ERROR_TRIGGER_TYPE`	String	`n8n-nodes-base.errorTrigger`	Specify which node type to use as Error Trigger.
`N8N_CUSTOM_EXTENSIONS`	String	-	Specify the path to directories containing your custom nodes.
`N8N_COMMUNITY_PACKAGES_ENABLED`	Boolean	`true`	Enables (true) or disables (false) the functionality to install and load community nodes. If set to false, neither verified nor unverified community packages will be available, regardless of their individual settings.
`N8N_COMMUNITY_PACKAGES_REGISTRY`	String	`https://registry.npmjs.org`	NPM registry URL to pull community packages from (license required).
`N8N_VERIFIED_PACKAGES_ENABLED`	Boolean	`true`	When `N8N_COMMUNITY_PACKAGES_ENABLED` is true, this variable controls whether to show verified community nodes in the nodes panel for installation and use (true) or to hide them (false).
`N8N_UNVERIFIED_PACKAGES_ENABLED`	Boolean	`true`	When `N8N_COMMUNITY_PACKAGES_ENABLED` is true, this variable controls whether to enable the installation and use of unverified community nodes from an NPM registry (true) or not (false).
`N8N_COMMUNITY_PACKAGES_PREVENT_LOADING`	Boolean	`false`	Prevents (true) or allows (false) loading installed community nodes on instance startup. Use this if a faulty node prevents the instance from starting.
