有人在另一个帖子中说它需要QT5。我尝试安装 QT5 但仍然遇到错误。

Answer 1

我在 Windows 上遇到了这个问题。另一个答案对我不起作用。

然而，运行这个确实：

pip install python-dotenv 

或者，如果您有pip3Python 3：

pip3 install python-dotenv

Answer 2

我认为问题与distribute包有关，而不是与dotenv. 更新pip并单独setuptools安装distribute，然后尝试dotenv再次安装。

更新pip并setuptools：

python -m pip install --upgrade pip setuptools

distribute单独安装：

pip install distribute

重试安装dotenv：

pip install dotenv
