ReactJs 錯誤：npm 啟動不工作，我還綁定了“npm cache clean --force”。 我被困在我的項目中間

Question

這是錯誤：

my-app@0.1.0 start /home/gaurav/Desktop/Django + React/Saurav Hardware/saurav_hardware/my-app react-scripts start

              }
            }

每次我嘗試啟動 npm 時都會發生這種情況。 它昨天工作正常，但完全停止了。我該怎么辦？ 這個 package.json 文件中缺少什么？ 我也無法安裝節點模塊......！

Answer 1

您尚未安裝所有模塊。 運行npm install以安裝package.json中指定的模塊，然后npm start工作。 請注意，找不到react-scripts的錯誤消息，這是您未安裝 package 的線索
