无法在 UBUNTU 上运行 Gatsy 项目

Question

我正在开发 Gatsby 项目并尝试在 UBUNTU 系统上运行它。尝试运行“npm install”时出现这样的错误。我从 git 存储库克隆了这个项目。在 Windows 上它工作正常，我可以用“gatsby develop”运行它，但在 UBUNTU 中它会抛出这样的错误...... 我该如何管理它？

Answer 1

关键是：

npm ERR! gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

Gatsby 和它们的一些依赖项和转换器（sharp、transformer-sharp，主要用于图像处理）是用 Python 编码的，因此它是一个强制依赖项。

在 Windows 中，由于windows-build-tools Python 依赖项是自动添加的，因此如果您从基于 Windows 的安装中克隆了 repo，则需要设置 Python。

尝试运行：

npm uninstall node-gyp -g
npm config set python python2.7
npm config set msvs_version 2015
npm cache clean -f
npm install

或者，您可以在您的机器上尝试installing and setting Python，然后重试该过程
