如何找到我的IDLE的Python，然后将pip升级应用到它使用的包中？

Question

我有两个python 2.7的兴趣：

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

我使用MacOS。 （我知道我已经迟到了切换到Python 3）

我想将pip install --upgrade PackageName应用到IDLE的Python使用的包中，但是当我在我的终端中键入它时，它会尝试将它应用到我的anaconda版本。

有没有办法可以找到我的IDLE的python，指向它，然后应用pip命令呢？

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：根据this answer，我打开了IDLE并打字

import sys
sys.executable

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

然后我打开了一个终端并进入了/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -m pip install --upgrade skyfield

我收到以下内容：

我关闭IDLE然后重新打开它，然后键入

import skyfield
skyfield.__version__

而且它仍然只有1.0

没有更新。

Skyfield目前正在版本1.10 https://rhodesmill.org/skyfield/installation.html，我今天使用1.10将我的anaconda版本成功升级到pip install --upgrade skyfield

Answer 1

要查找您的IDLE版本，请打开IDLE，然后转到菜单栏中的help部分。点击About IDLE，还有你的python版本！

要验证您的pip是否是您想要的版本，您只需键入以下内容：

pip -V

它会在Windows上给你这样的东西（MAC会类似）：

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

如果是不正确的路径，只需获取get-pip.py然后使用您希望它编译的python版本运行它，如下所示：

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

要使用您想要使用的点，请键入：

/usr/local/bin/pip install foo

Answer 2

在IDLE shell中，输入import sys; sys.executable，您将看到执行IDLE的python的完整路径。

要安装到该特定可执行文件，请输入Terminal path/to/python.exe -m pip install ...。
