npm ERR! errno 1
npm ERR! [email protected] install: `node install.js`

将

复制代码

 npm install

改成

复制代码

npm install --save-dev node-sass

node_modules安装问题，执行以下：

复制代码

rm -rf node_modules
rm package-lock.json
npm cache clear --force
npm install

这一步清除npm缓存很重要

复制代码

npm cache clear --force

3. npm install时,报错 install: `node install.js`安装失败

复制代码

 error [email protected] install: `node install.js`
 error Exit status 1
 error Failed at the [email protected] install script.

初步判断是这个zip文件没下载下来，然后手动下载一个chromedriver_win32.zip丢到C:\Users\用户\AppData\Local\Temp\chromedriver\目录下，结果因为这是一个临时文件夹，每次初始化的时候都会重新下载这个文件，从而又无法初始化解决方案：

1. 加参数

复制代码

npm install --ignore-scripts

2. 更换数据源

复制代码

npm install chromedriver --chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver
