因为我在Xcode中构建项目时遇到了这个错误，
ModuleNotFoundError: No module named 'requests'然后我尝试用git命令安装requests模块。
python toolchain.py pip install requests但是，我阅读了日志，我得到了这个FileNotFoundError消息。我该如何处理这个错误呢？

让我们分步骤来解决这个问题：
我假设您的
toolchain.py文件是您要运行的脚本，为此您需要requests模块。在使用
pip install <module>安装新模块之前，您希望激活虚拟环境，因为您希望将其安装在那里。您可以通过执行以下操作来执行此操作：
source <your-venv-path>/bin/activate<your-venv-path>\Scripts\activate.bat有关如何激活虚拟环境的一些好答案，可以在Windows和Linux中找到。
现在您的虚拟环境处于活动状态，您应该能够安装requests模块，如下所示：
pip install requests在此之后，您应该能够运行安装了requests模块的脚本，如下所示：
python toolchain.py
