求助,使用vue时安装node-sass报错

[beimyy]

使用vue时安装node-sass报错

在服务器上部署vue项目时,node-sass安装不了,导致项目不能build,特来此求助.

操作系统是centos7
```shell
[root@vm172-31-48-7 apps]# uname -sr
Linux 3.10.0-693.21.1.el7.x86_64
```

node版本
```shell
[root@vm172-31-48-7 vuetest]# node -v
v8.11.3
[root@vm172-31-48-7 vuetest]# npm -v
6.1.0

```
通过vue-cli搭建了项目
```shell
vue init webpack vuetest
cd vuetest
npm install
```
到这里一切正常.
安装sass-loader
```shell
[root@vm172-31-48-7 vuetest]# npm install sass-loader --save-dev --registry=https://registry.npm.taobao.org
```
安装成功,然后安装node-sass失败
```shell
[root@vm172-31-48-7 vuetest]# npm install node-sass --save-dev --registry=https://registry.npm.taobao.org

通过配置npm解决

npm config set user 0 
npm config set unsafe-perm true

应该是权限不够，用root试试

用sudo找不到命令
```shell
[root@vm172-31-48-7 vuetest]# sudo npm install node-sass --save-dev --registry=https://registry.npm.taobao.org
sudo: npm：找不到命令
```

仔细一看还真是root账户

看报错就是mkdir失败，看起来就是权限不够的样子。 算了，睡觉去，明天再来围观。
