How to change pip installation path
提问by xtt
I am using Mac. My pip installation path is /Library/Python/2.7/site-packages. How do I change it to ~/anaconda/lib/python2.7/site-packages/?
我正在使用 Mac。我的 pip 安装路径是/Library/Python/2.7/site-packages. 我如何将其更改为~/anaconda/lib/python2.7/site-packages/？
Oftentimes, the package installed by pip won't be found by my jupyter notebook and that's why I want to change the path.
通常，我的 jupyter notebook 找不到 pip 安装的包，这就是我想更改路径的原因。

You can tell pip where to install the package. Use the -tflag , that means the target directory where you want to install the package. Have have look at pip install --help
您可以告诉 pip 安装包的位置。使用-tflag ，这意味着要安装包的目标目录。有看过pip install --help
-t, --target <dir> Install packages into <dir>. By default this will not replace existing
files/folders in <dir>. Use --upgrade to replace existing packages in <dir> with
new versions.
You can change this on permanent basis by changing the pip.iniconfiguration file. See this for detail: pip install path
您可以通过更改pip.ini配置文件永久更改此设置。有关详细信息，请参阅：pip install path

在 Windows 上，配置文件是： %HOME%\pip\pip.ini %HOME% 位于
C:\Users\Bob on windows assuming your name is Bob
You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like
当您找到 pip 目录时，您可能需要创建 pip.ini 文件。在您的 pip.ini 或 pip.config 中，您将需要放置（假设您在 Windows 上）类似的内容
