react 启动异常 & 代码未做任何改动 =》怀疑安装elint时包有问题

错误日志:

撤销代码修改、配置修改,yarn start,错误同上(非代码、配置问题)

 

重新安装yarn: yarn install,错误同上(非 yarn版本问题)。

 

查找.gitignore文件:

# See https://help.github.com/articles/ignoring-files/ for more about ignoring files.

# dependencies
/node_modules
/dist
/__MOCK__
/.pnp
.pnp.js
/src/index.js

# testing
/coverage

# production
/build

# misc
.DS_Store
.env.local
.env.development.local
.env.test.local
.env.production.local

npm-debug.log*
yarn-debug.log*
yarn-error.log*
yarn.lock

  

 

删除文件夹:node_modules & dist

重新安装yarn: yarn install  (yarn install //安装package.json里所有包,并将包及它的所有依赖项保存进yarn.lock

重新运行:成功  (maybe:包安装冲突 or 包缺失)
