如何安装dotenv，避坑指南，安装包的包名有误？
嗨，大家好，我是蓝若姐姐。最近在研究AI大模型，想写一个调用openai接口的demo，结果发现在装一个三方库的时候一直报错，mac电脑安装dotenv报错，具体情况是
执行这个命令：
pip install dotenv
遇到报错：error: subprocess-exited-with-error，pip subprocess to install backend dependencies did not run successfully
以下是完整报错

error: subprocess-exited-with-error我尝试了很多的方法，大概包括以下几种：
- 更新 pip 到最新版本:
python -m pip install --upgrade pip
2.尝试重新创建虚拟环境:
# 删除原有虚拟环境
rm -rf venv# 创建新的虚拟环境
python -m venv venv
source venv/bin/activate
3.清理缓存并重新安装 dotenv 包:
pip cache purge
pip install dotenv
4.尝试手动下载 dotenv 包并安装:
# 下载 dotenv 包
wget <https://files.pythonhosted.org/packages/b6/ad/b1d7e6933c8ddd910efed44c8ffea8bf76e1c10b0114e06e0e78055ad10/dotenv-0.0.5.tar.gz># 解压并安装
tar -xzf dotenv-0.0.5.tar.gz
cd dotenv-0.0.5
python setup.py install
以上方法全部尝试过，还是不行，当然这上面大部分方案都是询问的chatGPT,最终没能解决问题，但是我并没有放弃，我可不是那么容易放弃的人，chatGPT不行，我转战谷歌，之前在谷歌搜索：如何安装dotenv，出来很多数据，我随意的点击了一个进去，看到了里面的内容之后，我如遭雷击，搞半天不是我安装的方式不对，而是我安装的包名错误，因为导入的代码如下
所以我想当然的使用了这个命令：
pip install dotenv结果dotenv根本不是正确的包名，正确的包名是：python-dotenv
所以正确的安装命令是
pip install python-dotenv后来我马不停蹄的输入这个命令执行，果然没有预期中的报错，果然成功安装，然后运行代码成功
