使用npm过程中几个小错误

1. 使用npm安装hexo-cli时报错：node-gyp

# npm install -g hexo-cli
/usr/local/bin/hexo -> /usr/local/lib/node_modules/hexo-cli/bin/hexo

> [email protected] install /usr/local/lib/node_modules/hexo-cli/node_modules/fsevents
> node install

坑爹的网络给出的答案是删除node-gyp，于是我就rm -rf node-gyp，把整个node-gyp目录干掉了

再次执行时，又出一个错：

npm ERR! Cannot find module '../node_modules/node-gyp/bin/node-gyp'

错误一，无法安装hexo-cli原因为无法下载，解决方案：使用cnpm再次执行命令即可：cnpm install -g hexo-cli

错误二，找不到模块，之前删掉了，再次安装即可：sudo npm install node-gyp -g

2. Error: ENOENT: no such file or directory, uv_cwd错误

将blog文件夹中的文件全部删除后，再次在Terminal中执行命令，报出以下错误:

path.js:1142
          cwd = process.cwd();
                        ^
Error: ENOENT: no such file or directory, uv_cwd

    at Object. (/usr/local/lib/node_modules/npm/bin/npm-cli.js:75:3)
    at Module._compile (module.js:570:32)

解决方案:

重启一个终端(Terminal)
