下面的命令对我有用:

sudo npm install -g appium --unsafe-perm=true --allow-root

对于linux / ubuntu如果命令

NPM install -g <package_name>

npm WARN deprecated superagent@4.1.0: Please note that v5.0.1+ of superagent removes User-Agent header by default, therefore you may need to add it yourself (e.g. GitHub blocks requests without a User-Agent header).  This notice will go away with v5.0.2+ once it is released.

修复:安装与根权限

Sudo NPM install <package_name> -g

它是100%的工作

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

你所需要做的就是将USER添加到/local/lib的所有者

sudo chown -R $USER /usr/local/lib

编辑:

要精确地定位并只定位node_modules文件夹，请在使用前一个命令之前尝试使用这个命令:

sudo chown -R $USER /usr/local/lib/node_modules

当在ubuntu中安装全局包时，你需要特殊的写入权限，因为你正在写入usr/bin文件夹。这是出于安全考虑。 所以，每次你安装一个全局包时，使用:

sudo npm install -g [package-name]

对于您的具体情况，它将是:

sudo npm install -g typescript

我尝试了@okanda给出的答案的解决方案，但对我不起作用。

然而，当我在这个线程中提到的几个文件夹中这样做时，它工作得很完美:https://github.com/angular/angular-cli/issues/9676#issuecomment-464857493

sudo chown -R $USER /usr/local/lib/node_modules/
sudo chown -R $USER /usr/local/bin/
sudo chown -R $USER /usr/local/share/
