我创建了一个自定义插件，我尝试通过cmd添加它以获得以下错误
> cordova plugin add C:\r\work\custom_plugins\cordova-plugin-webrtc-video-call -
-save
x Running command - failed!
[ERROR] Cordova encountered an error.
You may get more insight by running the Cordova command above directly.

我已尝试使用--nofetch选项，我使用的是cordova v7.0.1
答案 0 :(得分：6)
确保插件中没有要安装的node_modules的文件/符号链接。如果存在，请将其删除并重新运行命令：
cordova plugin add C:\r\work\custom_plugins\cordova-plugin-webrtc-video-call --nofetch
希望有所帮助。 :)
答案 1 :(得分：1)
SO上有几个关于这个问题的帖子。
看来cordova在您用于安装插件的本地路径和config.xml中有关该插件的信息之间丢失。
有些人似乎通过首先使用--force标志删除插件然后重新安装它来修复它：
cordova plugin remove cordova-plugin-webrtc-video-call --force
cordova plugin add C:\r\work\custom_plugins\cordova-plugin-webrtc-video-call
（ - 在cordova 7中保存似乎没用，因为插件没有添加到config.xml中）
当我遇到问题时，我通过清理项目中的所有插件并重新添加插件来修复它：
ps：插件中的xml文件名为plugin.xml而不是config.xml，对吗？
答案 2 :(得分：0)
--nofetch选项是解决此问题的方法：https://stackoverflow.com/a/46010348/327862
但是，自Cordova 8.0.0起，--nofetch选项已被删除：https://issues.apache.org/jira/browse/CB-13055
如果您已经安装了Cordova 8.x.x并想使用--nofetch选项，那么您需要将cordova降级到7.1.0。
运行以下命令将Cordova降级为7.1.0：
npm install -g cordova@7.1.0
如果上述命令不起作用，请先尝试卸载cordova，然后再安装cordova版本7.1.0：
npm uninstall -g cordova
npm install -g cordova@7.1.0
然后，检查Cordova版本以确认它是否降级：
cordova --version
