Note: Dependabot security and version updates are currently in private beta and subject to change. Please contact your account management team for instructions on enabling Dependabot updates.
注意：站点管理员必须先为 your GitHub Enterprise Server instance设置 Dependabot updates，然后你才能使用此功能。 有关详细信息，请参阅“对企业启用 Dependabot”。
If anything prevents Dependabot from raising a pull request, this is reported as an error.
When Dependabot is blocked from creating a pull request to fix a Dependabot alert, it posts the error message on the alert. The Dependabot alerts view shows a list of any alerts that have not been resolved yet. To access the alerts view, click Dependabot alerts on the Security tab for the repository. Where a pull request that will fix the vulnerable dependency has been generated, the alert includes a link to that pull request.
There are several reasons why an alert may have no pull request link:
Dependabot security updates are not enabled for the repository.
The alert is for an indirect or transitive dependency that is not explicitly defined in a lock file.
An error blocked Dependabot from creating a pull request.
If an error blocked Dependabot from creating a pull request, you can display details of the error by clicking the alert.
When Dependabot is blocked from creating a pull request to update a dependency in an ecosystem, it posts the error icon on the manifest file. The manifest files that are managed by Dependabot are listed on the Dependabot tab. To access this tab, on the Insights tab for the repository click Dependency graph, and then click the Dependabot tab.
To see the logs for any manifest file, click the Last checked TIME ago link, and then click View logs.
Pull requests for security updates act to upgrade a vulnerable dependency to the minimum version that includes a fix for the vulnerability. In contrast, pull requests for version updates act to upgrade a dependency to the latest version allowed by the package manifest and Dependabot configuration files. Consequently, some errors are specific to one type of update.
Security updates only. Dependabot cannot create a pull request to update the vulnerable dependency to a secure version without breaking other dependencies in the dependency graph for this repository.
Every application that has dependencies has a dependency graph, that is, a directed acyclic graph of every package version that the application directly or indirectly depends on. Every time a dependency is updated, this graph must resolve otherwise the application won't build. When an ecosystem has a deep and complex dependency graph, for example, npm and RubyGems, it is often impossible to upgrade a single dependency without upgrading the whole ecosystem.
The best way to avoid this problem is to stay up to date with the most recently released versions, for example, by enabling version updates. This increases the likelihood that a vulnerability in one dependency can be resolved by a simple upgrade that doesn't break the dependency graph. For more information, see "Configuring Dependabot version updates."
Dependabot cannot update to the required version as there is already an open pull request for the latest version
Security updates only. Dependabot will not create a pull request to update the vulnerable dependency to a secure version because there is already an open pull request to update this dependency. You will see this error when a vulnerability is detected in a single dependency and there's already an open pull request to update the dependency to the latest version.
There are two options: you can review the open pull request and merge it as soon as you are confident that the change is safe, or close that pull request and trigger a new security update pull request. For more information, see "Triggering a Dependabot pull request manually."
Dependabot took longer than the maximum time allowed to assess the update required and prepare a pull request. This error is usually seen only for large repositories with many manifest files, for example, npm or yarn monorepo projects with hundreds of package.json files. Updates to the Composer ecosystem also take longer to assess and may time out.
This error is difficult to address. If a version update times out, you could specify the most important dependencies to update using the
allow parameter or, alternatively, use the
ignore parameter to exclude some dependencies from updates. Updating your configuration might allow Dependabot to review the version update and generate the pull request in the time available.
If a security update times out, you can reduce the chances of this happening by keeping the dependencies updated, for example, by enabling version updates. For more information, see "Configuring Dependabot version updates."
There's a limit on the number of open pull requests Dependabot will generate. When this limit is reached, no new pull requests are opened and this error is reported. The best way to resolve this error is to review and merge some of the open pull requests.
There are separate limits for security and version update pull requests, so that open version update pull requests cannot block the creation of a security update pull request. The limit for security update pull requests is 10. By default, the limit for version updates is 5 but you can change this using the
open-pull-requests-limit parameter in the configuration file. For more information, see "Configuration options for the dependabot.yml file."
The best way to resolve this error is to merge or close some of the existing pull requests and trigger a new pull request manually. For more information, see "Triggering a Dependabot pull request manually."
If Dependabot attempts to check whether dependency references need to be updated in a repository, but can't access one or more of the referenced files, the operation will fail with the error message "Dependabot can't resolve your LANGUAGE dependency files." The API error type is
Similarly, if Dependabot can't access a private package registry in which a dependency is located, one of the following errors is generated:
- "Dependabot can't reach a dependency in a private package registry"
(API error type:
- "Dependabot can't authenticate to a private package registry"
(API error type:
- "Dependabot timed out while waiting for a private package registry"
(API error type:
- "Dependabot couldn't validate the certificate for a private package registry"
(API error type:
To allow Dependabot to update the dependency references successfully, make sure that all of the referenced dependencies are hosted at accessible locations.
Version updates only. 在运行安全性或版本更新时，有些生态系统必须能够解决来自其来源的所有依赖项，以验证版本更新是否成功。 如果清单或锁定文件包含任何私有依赖项，Dependabot 必须能够访问这些依赖项所在的位置。 组织所有者可以授予 Dependabot 访问包含同一个组织内项目依赖项的私有仓库. 有关详细信息，请参阅“管理组织的安全和分析设置”。 你可以在存储库的 dependabot.yml 配置文件中配置对专用注册表的访问。 有关详细信息，请参阅“dependabot.yml 文件的配置选项”。 Additionally, Dependabot doesn't support private GitHub dependencies for all package managers. For more information, see "About Dependabot version updates."
If you unblock Dependabot, you can manually trigger a fresh attempt to create a pull request.
- Security updates—display the Dependabot alert that shows the error you have fixed and click Create Dependabot security update.
- Version updates—on the Insights tab for the repository click Dependency graph, and then click the Dependabot tab. Click Last checked TIME ago to see the log file that Dependabot generated during the last check for version updates. Click Check for updates.
