Android Ionic Cordova - 错误：无法获取已安装模块的绝对路径

Question

我已经创建了一个自定义插件，我正在尝试通过 cmd 来添加它，得到以下错误

> 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.

我已经尝试过使用 --nofetch 选项，我正在使用 cordova v7.0.1

Answer 1

确保在要安装的 node_modules 中没有插件的文件/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

希望对您有所帮助。 :)

Answer 2

在 SO 上有几篇关于这个问题的帖子。

您用于安装插件的本地路径与 config.xml 中有关该插件的信息之间似乎丢失了cordova。

有些人似乎通过首先删除带有 --force 标志的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

（-save 在cordova 7 中似乎没用，因为插件被添加到 config.xml 没有那个）

当我遇到问题时，我通过清除项目中的所有插件并重新添加插件来解决它：

1. 删除插件文件夹
2. 删除platforms/android文件夹
3. 删除 config.xml 中的所有插件引用
4. 将所有插件重新添加到项目中

ps：你插件中的xml文件是plugin.xml而不是config.xml吧？

Answer 3

--nofetch 选项是解决此处提到的问题的方法：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 并且想要使用 --nofetch 选项，那么您需要将 cordova 降级到 7.1.0。

运行以下命令将 Cordova 降级到 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，然后安装cordova 7.1.0版本：

npm uninstall -g cordova
npm install -g cordova@7.1.0

然后，检查 Cordova 版本，确认是否降级：

cordova --version
