安装Node-js移除ros旋律桌面满

Question

我试图安装npm，但是我得到了一个错误: npm :依赖: not (>= 0.10.9)，但是它不会被安装。

于是我在互联网上找到了一个答案：npm :取决于: not (>= 0.10.9)，但它不会被安装

我写

sudo apt-get install nodejs-dev node-gyp libssl1.0-dev

到控制台，它移除了很多东西，下面是几个：

dpkg: libignition-fuel-tools1-dev:amd64: dependency problems, but removing anyway as you requested:
 libgazebo9-dev:amd64 depends on libignition-fuel-tools1-dev.

现在，ros项目没有运行，我使用的是PX4-Autopilot，现在它没有运行。

$ make px4_sitl gazebo

产出如下：

这一切为什么要发生？如果我重新安装Ros和其他软件包，他们会删除节点吗？

具体的冲突是ROS旋律和称为libcurl4-gnutls-dev的NPM依赖之间的冲突。这是依赖链: NPM ->节点-gyp -> nodejs -> libssl1.0-dev -> libcurl4-gnutls-dev
