无法将" Gatsby - plugin -netlify-cms“插件安装到Gatsby博客

Question

我无法将Gatsby plugin for Netlify CMS安装到我的博客。我一直在学习将Netlify CMS添加到现有博客中教程，也提到了这个文档。

复制步骤

这里有一个链接到我的回购：https://github.com/mohammedasker/blogger

1. 克隆我的repo并转到项目目录。
2. 运行npm install --save netlify-cms-app gatsby-plugin-netlify-cms

预期结果

成功安装了Gatsby plugin for Netlify CMS。

实际效果

安装Netlify CMS的Gatsby插件时出错。

这是我从终端获得的错误日志：

我试过的东西

我尝试在其他Gatsby项目中安装插件，并以root/Administrator (命令提示符)的身份再次运行该命令。不幸的是，它们都没有起作用。

Answer 1

正如错误显示的那样：

您的操作系统拒绝了该操作。该文件可能已经在使用(由文本编辑器或防病毒)，

在不运行gatsby develop的情况下重试相同的操作。

出现这些错误是因为在运行gatsby develop时，您正在读取node_modules文件夹，因为许多功能都使用它(作为导入、活动重载等)。当程序读取这些文件时，系统无法覆盖或安装/添加其他来源的新文件夹(本例中为npm)，因为您的操作系统正在使用它们。

Answer 2

在运行Gatsby plugin for Netlify CMS之前安装gatsby develop插件解决了这个问题。
