pkg_resources.DistributionNotFound: The 'pip==9.0.1' distribution was not found and is required by the application

答案1

通过 python 调用 pip 对我来说很有效，例如：

python3 -m pip install --upgrade pip==9.0.1

（或您在 中看到的任何版本Requirement.parse('pip==X.Y.Z')）

答案2

您需要先升级pip：

pip3 install --upgrade pip

答案3

您收到以下错误消息：

'pip==9.0.1' distribution was not found and is required by the application

pip 9.0.1 是 pip 当前的最新版本。要将 pip3 升级到版本 9.0.1，请运行以下命令。

sudo -H pip3 install --upgrade pip  
sudo -H pip3 install django==1.11 # latest django long term support release

这在我的系统上运行良好，系统安装有 pip3 9.0.1。结果如下所示。（如果这些命令不起作用，请将错误消息粘贴到您的问题中。）
