Question

我有两个感兴趣的python 2.7：

IDLE来自https://www.python.org/downloads/的版本
anaconda 2.7安装

我使用MacOS。（我知道我该改用Python 3了。）

我想将pip install --upgrade PackageName应用于IDLE的Python使用的软件包，但是当我在终端中键入该软件包时，它将尝试将其应用于我的anaconda版本。

有没有办法找到我的IDLE的python，指向它，然后对其应用pip命令？

这就是我所拥有的：

$ which python

/Users/david/anaconda2/bin/python

$ which -a python

/Users/david/anaconda2/bin/python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
/usr/local/bin/python
/usr/bin/python

更新：每this answer，我打开IDLE并输入

import sys
sys.executable

，它返回了/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python。

然后我打开一个终端并输入/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -m pip install --upgrade skyfield

我收到了以下信息：

我关闭IDLE，然后重新打开它，然后键入

import skyfield
skyfield.__version__

仍然只有1.0

没有更新。

Skyfield当前的版本为1.10 https://rhodesmill.org/skyfield/installation.html，我今天使用1.10将anaconda版本成功升级到了pip install --upgrade skyfield

Answer 1

要找到您的IDLE版本，请打开IDLE，然后转到菜单栏中的help部分。点击About IDLE，就有您的python版本！

要验证您的点子是否是您想要的版本，只需输入以下内容即可：

pip -V

它将在Windows上为您提供类似的信息（MAC将类似）：

pip 19.0.2 from c:\python27\lib\site-packages\pip (python 2.7)

在错误路径的情况下，只需获取get-pip.py，然后使用要编译的python版本运行它即可：

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

要使用您想使用的点子，请输入以下内容：

/usr/local/bin/pip install foo

Answer 2

在IDLE外壳程序中，输入import sys; sys.executable，您将看到执行IDLE的python的完整路径。

要安装到该特定的可执行文件，请在终端path/to/python.exe -m pip install ...中输入。

如何找到我的IDLE的Python，然后将pip升级应用于它使用的软件包？
