Dependent component information extraction method and device and computer readable storage medium

The invention discloses a dependent component information extraction method and device and a computer readable storage medium. The dependent component information extraction method comprises the steps of obtaining a to-be-detected package manager configuration file list; for each configuration file in the configuration file list, intercepting a part of text segments related to the dependency declaration, and performing matching by using a regular expression to obtain component information of a component directly dependent on the configuration file; based on the component information of the direct dependent component, obtaining the component information of the indirect dependent component by searching a component dependent knowledge base; and displaying the component information of the direct dependent component and the component information of the indirect dependent component. By the adoption of the invention, text analysis depending on the configuration file can be achieved, dependence constraints such as a
