在mac电脑上运行报错 mac系统版本macOS 12.7.6

node版本14.8.0
Ask小助手
根据您提供的报错信息和
package.json，此问题通常与@vue/cli-service版本或node.js版本有关。在您的
package.json中，@vue/cli-service的版本为~5.0.0。根据社区反馈，uni-app 的 vue2 项目在使用 vue-cli 5.x 时可能会出现TypeError: Cannot convert undefined or null to object的报错，因为 uni-cli 对 vue-cli 5.x 的兼容性可能存在问题。您可以尝试以下两种解决方案：
降级 vue-cli 版本：将项目中的
@vue/cli-service、@vue/cli-plugin-babel等 vue-cli 相关依赖降级到 4.x 版本（例如 4.5.14）。您可以修改package.json中的版本号后重新安装依赖，或者执行以下命令：升级 node.js 版本：部分用户反馈此问题是由于 node.js 版本过低导致的，将 node.js 版本升级到 16 或以上可以解决此问题。
