不到万不得已不要是要sudo权限

  • teminal 终端出现了这个错误，警告中出现了 missing，这个是提示 root权限不允许，需要在npm 命令欠加 sudo。sudo是给予 root权限的，会车以后会出现一个 ？的密码，别担心：这个输入电脑登录密码就好，输入的时候屏 幕上不会出现几位数，是为了防止别人看到几位数来破解，输入密码后回车就好。

  • 下面出现了一个 no such file or directory, access ‘/Users/a1/github/samplate/node_modules/_nervjs@1.3.13@nervjs/node_modules/nerv-shared’

    这是少了什么包，下载那个缺失的包就好。输入 sudo npm install nerv-shared 就好，然后再运行sudo npm i ,继续 sudo npm i taro-ui - S ,继续往下进行。

  • 由于本次在npm的解决问题上使用了 cnpm 的install插曲， 所以需要 执行 cnpm i 的全部下载操作，然后再进行 sudo npm i /sudo npm i taro-ui -S 操作。cnpm需要翻墙。

  • 开发环境搭建的时候不需要翻墙，翻墙会下载很多不需要的东西，速度会很慢，下载的时候如果翻墙了中途不能中断，会出现很多问题，最好搭建的时候不要翻墙。
