npm install express失败。ENETUNREACH错误

Question

我尝试在树莓派上安装express已经有几个小时了。不太确定问题是什么。

pi@raspberrypi:~ $ npm -v
8.1.0

pi@raspberrypi:~ $ node -v
v17.0.1

pi@raspberrypi:~/Project-Folder $ npm install

up to date, audited 1 package in 803ms

found 0 vulnerabilities

npm install运行良好，但是当我尝试访问注册表时，它失败了。

pi@raspberrypi:~/Project-Folder $ npm install -g express
npm ERR! code ENETUNREACH
npm ERR! syscall connect
npm ERR! errno ENETUNREACH
npm ERR! request to http://registry.npmjs.com/express failed, reason: connect ENETUNREACH 0000:0000::0000:0000:80

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/pi/.npm/_logs/2021-10-26T17_22_03_292Z-debug.log

它实际上没有那个ip地址，我只是不想泄露任何东西。

我已经做了下面的所有事情。

npm config set registry https://registry.npmjs.org/ -失败

npm config set registry https://registry.npmjs.com/ -失败

npm config set registry http://registry.npmjs.org/ -失败

npm config set registry http://registry.npmjs.com/ -失败

npm cache clean -失败

nslookup返回以下内容

pi@raspberrypi:~ $ nslookup registry.npmjs.org

我已经看了很久了，似乎每个人都通过更改注册表来修复这个问题。这对我不管用。

这不是网络问题。下面是来自MacBook专业版的相同网络。

username Project-Folder % npm install -g express

added 50 packages, and audited 51 packages in 2s

感谢您所能提供的任何帮助。

问题最终是我的本地网络不支持IPv6，所以我只需要在我的树莓派上禁用它，这个问题就解决了。

检查是否启用了IPv6。

使用ifconfig

如果它包含inet6，则已启用IPv6

要禁用

sudo nano /etc/sysctl.conf

在结尾处添加这个：

net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1
net.ipv6.conf.eth0.disable_ipv6 = 1

sudo nano /etc/rc.local

将此代码添加到末尾(但在“exit 0”之前)：

service procps reload

重新启动Pi

sudo reboot

使用ifconfig并查找inet6如果它没有出现，则IPv6被禁用
