使用pip在osx 10.10.3上安装scrapy的问题

Question

我无法在osx 10.10.3上安装Scrapy。 我运行了pip install Scrapy，并收到以下错误消息，指示无法安装twis​​ted。 我运行xcode-select --install以确保安装了xcode工具。 我也尝试过运行sudo pip install Scrapy。 有什么建议么？

这是我收到的错误消息：

Answer 1

提示就在错误消息中：

同意Xcode / iOS许可证需要管理员权限，请通过sudo以root身份重新运行。

但是，我建议不要以root用户身份运行实际安装 。 只需接受一次XCode许可即可

sudo xcodebuild -license

然后重新运行安装即可解决问题。
