技术标签: node.js 前端 npm vue.js javascript
在新版nodejs已经集成了npm,所以npm也都安装好了。可以通过输入下面命令来测试是否成功安装
node -v
npm -v
如果安装成功,都会出现版本号
用npm -v测试,报错:
node:internal/modules/cjs/loader:936
throw err;
^

解决办法:
1.卸载重装
2.以管理员方式运行
配好npm之后,在项目中报错,
输入安装依赖命令
npm install
报错如下:

解决办法:
删除npmrc文件,需要注意的是:不是nodejs安装目录npm模块下的那个npmrc文件,而是在C:\Users{账户}\下的.npmrc文件.
继续安装依赖:
npm install
出现下面结果:

原因:默认的安装源是国外网站,国内访问不了无法获取依赖包信息。
解决办法:添加
npm config set registry http://registry.npm.taobao.org/
其他常见命令:
# 查看自己的安装源
npm config get registry
# 更换npm源为国内淘宝镜像
npm config set registry http://registry.npm.taobao.org/
# 或者更换为国内npm官方镜像
npm config set registry http://registry.cnpmjs.org/
# 还原npm源
npm config set registry https://registry.npmjs.org/
继续执行:
npm install
