Python 安装MODEL报错WARNING version xx is available

Posted 2022-03-02 Adorable_Rocy

Q1:在安装模块的时候发现系统报错如下：

ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: 'C:\\\\Users\\\\Dell\\\\AppData\\\\Local\\\\Temp\\\\pip-req-tracker-_nyodpl_\\\\e497bd74205deb88b286d3556502f61a4d67dd2b0bf63d8a57f23ee7'

WARNING: You are using pip version 20.2.3; however, version 22.0.3 is available.
You should consider upgrading via the 'c:\\users\\dell\\pycharmprojects\\untitled1\\venv\\scripts\\python.exe -m pip install --upgrade pip' command.

意思是pip版本太低了，上面很明显的说明了需要安装更高的版本，解决方式如下：

C:\\Users\\Dell>python -m pip install --upgrade pip

Q2:看似安装成功了，但是在添加MODEL的时候依旧报错

一大堆的红色失败字体引入眼帘，我们只好暴力重装了

重新装一遍之后，Successfully installed pandas
