我之前在这台机器上安装了phantomjs，但现在它找不到可执行文件了。所以我卸载它（npm uninstall phantomjs，npm uninstall phantomjs-prebuild）。
但安装它不起作用。有人可以告诉我为什么/如何解决它？
$ sudo -H npm -g install phantomjs-prebuilt
/usr/bin/phantomjs -> /usr/lib/node_modules/phantomjs-prebuilt/bin/phantomjs
> [email protected] install /usr/lib/node_modules/phantomjs-prebuilt
> node install.js
Considering PhantomJS found at /usr/bin/phantomjs
Looks like an `npm install -g`

虽然回答这个问题已经太晚了，但我仍然会继续这样做。
通过这样做，我得到了它的工作
sudo npm install -g [email protected] --unsafe-perm
检查评论here
只是一个快速修复：
# Install locally (in my case: ~/node_modules)
$ npm install phantomjs-prebuilt
# Add to path
$ cd ~/bin
~/bin$ ln -s ../node_modules/phantomjs-prebuilt/bin/phantomjs
# Check if it worked
$ phantomjs --version
2.1.1
我也遇到了这个错误并找到了2个解决方案：
npm config list --json | grep "user\|unsafe-perm"）
如果nesseccary改变你的npm-config
npm config set user 0以root身份运行包脚本时设置的UID。
npm config set unsafe-perm true设置为true以在运行程序包脚本时禁止UID / GID切换。如果显式设置为false，则以非root用户身份安装将失败。
