NPM通过package.json安装Express时出错 [英] Error in NPM installing express via package.json

问题描述

我的节点和npm版本是最新的.但是在./node_modules下出现错误并且没有快速文件夹.Express文件夹位于/home/vagrant/.npm下生成npm-debug.log.不确定如何附加.

My node and npm versions are recent. But getting error and no express folder is coming up under ./node_modules. Express folder is coming up under /home/vagrant/.npm npm-debug.log is generated. Not sure how to attach that.

推荐答案

您需要使用-no-bin-link 选项运行npm，以告诉npm您的文件系统不支持链接

You need to run npm with -–no-bin-link option to tell npm that your filesystem doesn't support links

如果要在每个npm命令上执行-no-bin-link ，则可以使用以下命令将别名添加到主目录中的 .bashrc 文件中:该命令:

If you want to do the --no-bin-link on each npm command, you can add an alias to your .bashrc file in your home directory with this command:

echo "alias npm='npm --no-bin-links'" >> /home/vagrant/.bashrc

另一种可能性是将您的配置设置为允许Vagrantfile中Windows主机上的符号链接

Another possibility is to set your configuration to allow symlinks on Windows hosts in your Vagrantfile

config.vm.provider "virtualbox" do |v|
    v.customize ["setextradata", :id, "VBoxInternal2/SharedFoldersEnableSymlinksCreate/vagrant", "1"]
end
