Fedora 26系统Python3.6环境安装datatable失败求助

Hey there! This error isn’t normal—let’s break down why it’s happening and get datatable installed properly.

Why this error pops up #

The wheel file you’re targeting is built for linux_x86_64, but older pip versions or Fedora’s specific system labeling can make pip misjudge compatibility. Also, datatable depends on some system-level libraries that might be missing from your Fedora 26 setup.

Step-by-step solutions #

1. Upgrade pip first #

Older pip versions often struggle to recognize valid wheel files. Update pip with this command:

pip install --upgrade pip

After upgrading, try re-running your original wheel installation command to see if it works.

2. Install required system dependencies #

Datatable needs several system libraries to run or compile correctly. Install them using Fedora’s package manager:

sudo dnf install libcurl-devel openssl-devel gcc-c++ git

3. Install datatable from source (most reliable for your setup) #

If the wheel still fails, compiling from source bypasses the platform compatibility check. Here’s how:

• Clone the datatable repository:

  git clone https://github.com/h2oai/datatable.git
  

• Navigate into the repo directory:

  cd datatable
  

• Check out the exact 0.3.2 version you need:

  git checkout 0.3.2
  

• Install from the source code:

  pip install .
  

Quick tip #

If you’re using a virtual environment (highly recommended for Python projects), activate it before running any of these commands to avoid messing with your system-wide Python installation.
