使用 pip 在 Mac 上安装 Pandas

Question

I am trying to install Pandas with pip , but ran into to a problem. Here are the details:

Mac OS Sierra
which python => /usr/bin/python
python --version => Python 2.7.10
Inside "/System/Library/Frameworks/Python.framework/Versions" there is the following
2.3 2.5 2.6 2.7 Current

I want pandas to be linked to Python 2.7.10 in "/usr/bin/python"

When I do pip install pandas , I get the following error message:

Collecting pandas

Thanks for helping.

Answer 1

Try running the pip install command as sudo.

sudo pip install pandas

Python packages are installed in the operating systems file system where not all users have permission to write files to. This is why you need to run the command as sudo, as sudo elevates your privileges to do this.

Edit: This seems to be getting some upvotes so I've added some clarity to this question regarding user specific installation. You can also install this just for your user should this fit your use case with: pip install --user pandas .

Answer 2

如果你在Python 3.0上， pip3 install pandas而不是pip install pandas应该可以解决问题

Answer 3

在终端窗口上运行pip3安装pandas在MAC OS上为我工作。

Answer 4

for mac terminal using mojave works with

pip3 install pandas

or

pip3 install --upgrade pip

after

pip install pandas

Answer 5

Yes, running with sudo should solve the problem. Although its frowned upon . You can also do: pip install --user <packagename>

Also, I highly recommended using anaconda to manage python versions for you.

Answer 6

除了其他答案之外，我还必须考虑使用 MacOS 上的一些编译器特定问题

sudo CFLAGS='-Wno-implicit-function-declaration' pip3 install pandas
