Question

我正在尝试制作我的第一个汇合宏，我正在按照此处列出的说明进行操作：https：//developer.atlassian.com/cloud/confluence/getting-started/？_ga=2.78735767.2027190294.1547046060-2004234667.1546438516

目前，我在执行步骤 2 和 4 时遇到问题;NPM 安装和 NPM 启动：

收到以下错误：

Answer 1

先运行npm cache clean --force，然后运行npm install，然后运行npm start

这应该可以解决它。

--或者删除node_modules文件夹并重新运行npm install

--或1. npm 缓存清理 --强制

2. 删除node_modules和package-lock.json ，

3. npm 安装
