angular项目错误

Question

刚拿到一个项目要做二次开发，是一个angular项目，我拿到后yarn install 装上所有插件，然后ng serve，报了很多错误，蒙圈了。
先报了很多行lodash的错误。我这里就放了3行，差不多有好几十行错误。
ERROR in /Users/www/quanke3.0/node_modules/@types/lodash/common/object.d.ts (1405,67): ';' expected.
ERROR in /Users/www/quanke3.0/node_modules/@types/lodash/common/object.d.ts (883,45): Cannot find name 'ObjectIterator'.
ERROR in /Users/www/quanke3.0/node_modules/@types/lodash/common/object.d.ts (893,31): Cannot find name 'ObjectIterator'.

第二块错误。
/Users/www/quanke3.0/src/app/patients/medical-records-details/diagnosis-orders/doctor-orders/order-laboratory/order-laboratory.component.ts (102,15): Property 'pick' does not exist on type 'LoDashStatic'.

第三块错误
ERROR in ./node_modules/css-loader?{"sourceMap":false,"importLoaders":1}!./node_modules/postcss-loader?{"ident":"postcss"}!./node_modules/@angular/cli/node_modules/sass-loader/lib/loader.js?{"sourceMap":false,"precision":8,"includePaths":[]}!./src/styles.scss

yarn remove lodash @types/lodash
yarn add lodash
按照这步，lodash 的错误没了,不过有以下错误，有什么影响

warning " > @ngx-loading-bar/core@2.2.0" has incorrect peer dependency "@angular/common@>=5.0.0".
warning " > @ngx-loading-bar/core@2.2.0" has incorrect peer dependency "rxjs@^5.6.0-forward-compat.0 || ^6.0.0-beta.0".
warning " > ng-zorro-antd@0.5.5" has unmet peer dependency "@angular/cdk@2.0.0-beta.8".
warning "@angular/cli > @ngtools/webpack@1.6.2" has unmet peer dependency "enhanced-resolve@^3.1.0".

然后yarn add sass 它提示node版本大于4并小于9
The engine "node" is incompatible with this module. Expected version ">=4 <=9". Got "18.16.0"
我node切换 v8.17.0，又提示我
sass@1.78.0: The engine "node" is incompatible with this module. Expected version ">=14.0.0". Got "8.17.0"
这该怎么弄？
请问这些错误应该怎么解决？

1. 重新安装YARN和NPM。
2. 检查ANGULAR版本是否正确。
3. 确认你的NODE.JS环境是正确的。
4. 检查ANGULAR项目的配置文件是否有错误。
5. 如果以上步骤都正常，可能是你正在使用的是旧版本的ANGULAR版本或者某些依赖项与你的新环境不兼容导致的问题。你可以尝试更新到最新的ANGULAR版本或重新安装NGA来解决问题。
