npm ERR！当运行npm安装时，代码为ELIFECYCLE

Question

每次在样板项目上运行npm安装时，我都会收到以下错误：

ERROR in multi react-color moment ag-grid ag-grid-react es6-promise react-dom-factories react-spinners sortablejs
Module not found: Error: Can't resolve 'react-spinners' in 'C:Codereact-boilerplate'

我该怎么解决这个问题？

编辑：

运行npm install -S react-spinners && npm install后得到这个：

ERROR in multi react-color moment ag-grid ag-grid-react es6-promise react-dom-factories react-spinners sortablejs
Module not found: Error: Can't resolve 'sortablejs' in 'C:Codereact-boilerplate'
@ multi react-color moment ag-grid ag-grid-react es6-promise react-dom-factories react-spinners sortablejs vendor[7]

Answer 1

错误告诉您没有安装react-spinners和sortablejs。你可以安装它们并将它们添加到你的dependencies中，它就会工作：

npm i -S react-spinners sortablejs && npm install

可能是其他软件包将react-spinners和sortablejs作为peerDependecies，也可能是您之前安装了这些软件包而没有将它们添加到dependencies中，如果删除node_modules并重新安装，则会导致错误。
