Question

我在Mac osx上安装了2个python安装程序。

$ which python
/usr/bin/python

$ which python3
/Library/Frameworks/Python.framework/Versions/3.4/bin/python3

$ pip install --upgrade setuptools

$ which pip
/Library/Frameworks/Python.framework/Versions/3.4/bin/pip

$ pip -V
pip 18.1 from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/pip (python 3.4)

我可以用pip fine安装模块。例如 $ python3 -m pip install --user张量流成功安装了absl-py-0.6.1 astor-0.7.1 gast-0.2.0 grpcio-1.17.1 markdown-3.0.1 protobuf-3.6.1 tensorboard-1.12.1 tensorflow-1.12.0 termcolor-1.1.0 werkzeug -0.14.1

但是当我尝试用熊猫做同样的事情时 $ python3 -m pip install-用户熊猫

它通过收集和下载依赖项一直进行到最后，但由于以下错误而出错。

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/d5/k1w6m6xj5g727x952sdkkc1r0000gn/T/pip-install-r4n38agj/pandas/

问题似乎是它正在使用Python，而应该在python setup.py egg_info中使用python3

我如何确保pip在脚本中使用python3或是否存在其他问题？

Answer 1

您可以使用下面给出的任何代码

    imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            if(isFirstTimeClick){
                isFirstTimeClick=false;
                Toast.makeText(PicturePreviewActivity.this, "First Time Click", Toast.LENGTH_SHORT).show();
            }else {
                isFirstTimeClick=true;
                Toast.makeText(PicturePreviewActivity.this, "Second Time Click", Toast.LENGTH_SHORT).show();
            }
        }
    });

OR

pip3 install pandas --no-build-isolation

OR

sudo apt-get install python3-pip
sudo -H pip3 install pandas

OR

sudo pip install pandas

，对于使用mojave的mac终端，

pip install --user pandas

或

pip3 install pandas

之后

pip 3 install --upgrade pip

在Mac上使用pip安装pandas模块时出现问题
