今天用pip install flask时，总因为uninstall blinker失败，报错如下：

```

ERROR: Cannot uninstall 'blinker'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

解决办法 卸载blinker版本再安装，命令如下： ``` apt-get remove blinker 1.4 sudo -H pip install --ignore-installed -U blinker ``` 最后再次安装flask尝试，终于安装成功了：
