如何在OpenSUSE Leap 15.2上清理并重新安装NPM和NodeJS？

如何解决如何在OpenSUSE Leap 15.2上清理并重新安装NPM和NodeJS？

以root身份，我在OpenSUSE Leap 15.2 linux服务器上的/ usr / local / bin和/ usr / local / lib中删除了一些目录，以清理一些nodejs模块。然后，我使用Zypper（nodejs）卸载了npm和zypper remove nodejs npm。我在根目录的主目录中删除了“ .npm”目录。我从/为“ node_modules”做了一个find，但没有找到。之后，我安装了'nodejs'和'npm'（zypper install nodejs npm），并报告说已成功安装了它们。但是当我执行'npm -v'时，它失败并显示/usr/local/bin/npm: No such file or directory。我尝试多次卸载/重新安装这些软件包，但是npm始终失败并显示此错误。我有下面的输出。任何帮助将不胜感激。

解决方法

尝试强制重新安装节点和npm软件包。如果我没记错的话，可以通过以下方式做到这一点：

$ zypper in -f $(rpm -qa nodejs* --qf '%{NAME} ')
$ zypper in -f $(rpm -qa npm* --qf '%{NAME} ')

,

我必须执行以下操作：

rm -rf node_modules
rm -rf package_lock.json

在它们安装的所有位置（请记住：npm将它们安装在您执行npm install <module_name>的任何目录中）。 find在Linux上是一个有用的命令，用于跟踪所有这些目录。另外，我还必须从所有用户（不仅仅是根用户）中删除.npm目录。完成这些之后，然后使用zypper重新安装nodejs和npm成功。没有其他为我工作。祝你好运。
