新建了一个conda环境"tf2"，在该环境内想要使用pip命令下载第三方包，结果出现问题：

Script file 'D:\software\Anaconda3\envs\tf2\Scripts\pip-script.py' is not present.

在网上查找解决方案后，使用easy_install命令进行安装，安装过程中的打印内容如下：

(tf2) C:\Users\DESNY>easy_install pip

虽然打印内容显示安装成功，但是再一次想要使用pip命令的时候依旧报之前的错误。

又仔细查看了一遍打印内容，发现pip相关文件都安装在用户文件夹下，而不是安装在conda环境的文件夹下，于是尝试将c:\users\desny\appdata\local\programs\python\python39\Scripts文件夹下的pip-script.py、pip.exe、pip3-script.py、pip3.exe、pip3.8-script.py、pip3.8.exe六个文件复制到D:\software\Anaconda3\envs\tf2\Scripts文件夹下。

再次使用pip命令就正常了。
