在 Mac 上安装 pip

Question

I was trying to install my dependencies of a project I did in a windows. But every time it complains about dependencies of nltk especially regex. I'm trying to do in virtual environment of python 3.7.5.

Complete output (17 lines):

Answer 1

xcode-select --install

执行此命令后，这将在您的系统上更新或安装 clang。

Answer 2

Are you having problem after the update? Then your developer path is not set.

If you have XCODE then to setup the path you need to

1. Go to preference in Xcode

2. Go to Locations tab

3. Select Command Line Tools version from dropdown
