今天在npm install 的時(shí)候報(bào)依賴(lài)錯(cuò)誤

不管是重新拉去代碼户辞，還是重新install 都不能解決這個(gè)問(wèn)題武通，后來(lái)比較了新舊電腦的兩個(gè)項(xiàng)目渴频，原來(lái)是新缺少了package-lock.json這個(gè)文件桑驱。
package-lock.json這個(gè)文件的作用是鎖定依賴(lài)版本號(hào)懂盐，具體到特定的版本逸嘀，例如
"node_modules/@amap/amap-jsapi-loader": {
"version": "1.0.1",
"resolved": "https://registry.npmjs.org/@amap/amap-jsapi-loader/-/amap-jsapi-loader-1.0.1.tgz",
"integrity": "sha512-nPyLKt7Ow/ThHLkSvn2etQlUzqxmTVgK7bIgwdBRTg2HK5668oN7xVxkaiRe3YZEzGzfV2XgH5Jmu2T73ljejw=="
},
"node_modules/@ant-design/colors": {
"version": "5.1.1",
"resolved": "https://registry.npmjs.org/@ant-design/colors/-/colors-5.1.1.tgz",
"integrity": "sha512-Txy4KpHrp3q4XZdfgOBqLl+lkQIc3tEvHXOimRN1giX1AEC7mGtyrO9p8iRGJ3FLuVMGa2gNEzQyghVymLttKQ==",
"dependencies": {
"@ctrl/tinycolor": "^3.3.1"
}
},
"node_modules/@ant-design/icons-svg": {
"version": "4.1.0",
"resolved": "https://registry.npmjs.org/@ant-design/icons-svg/-/icons-svg-4.1.0.tgz",
"integrity": "sha512-Fi03PfuUqRs76aI3UWYpP864lkrfPo0hluwGqh7NJdLhvH4iRDc3jbJqZIvRDLHKbXrvAfPPV3+zjUccfFvWOQ=="
},
而package.json只能描述大版本號(hào)，因此在添加完package-lock.json文件之后允粤，在此執(zhí)行npm install 后成功安裝了依賴(lài)
