在 Ubuntu 18.04 上安装 Pandas 时出错

Question

I am installing cdqa through the command "pip3 install cdqa", in pycharm virtual environment, but during installation I get this error:

command x86_64-linux-gnu-gcc failed with exit status 1 ERROR: Failed building wheel for pandas

I tried installing pandas separately and it successfully installs Installing collected packages: pandas Successfully installed pandas-1.1.5

When i again install cdqa, it stucks on "Building wheels for collected packages: pandas Building wheel for pandas (setup.py)"
and gives the same error.

Tried on Jupiter Notebook and Pycharm both.

I am on Ubuntu 18.04 desktop version. Python 3.8.6

Any suggestions?

The cdqa repo says

⛔ [NOT MAINTAINED] This repository is no longer maintained, but is being kept around for educational purposes. If you want a maintained alternative to cdQA check out: https://github.com/deepset-ai/haystack

so you should probably switch to that.

As for why you're getting this issue, cdqa is locked to pandas==0.25.0 , which is positively ancient, and as such there is no Python 3.8 Linux binary wheel, which means Python is attempting to build it from source. That generally fails unless you've got all the development packages you need. When you just pip install pandas , you're getting a newer version from a binary wheel you don't need to compile.
