[英]How can I solve the connection problem during npm install behind a proxy?
我按照说明操作: https : //www.electronjs.org/docs/tutorial/first-app
我输入了mkdir
、 cd
和npm init
。 他们都工作得很好。 出现了一个名为package.json
文件。
然后我输入npm install --save-dev electron
。 发生了一些错误。
lala@ubu:~/projects/electron/my-app 17:20:34
$ npm install --save-dev electron
> core-js@3.6.4 postinstall /home/lala/projects/electron/my-app/node_modules/core-js
> node -e "try{require('./postinstall')}catch(e){}"
Thank you for using core-js ( https://github.com/zloirock/core-js ) for polyfilling JavaScript standard library!

执行上述指令后,出现一个文件夹node_modules
和一个文件package-lock.json
。
看来我已经成功安装了依赖项。 但是为什么会出现一个连接错误呢?
我无法直接访问github.com(13.250.177.223)
,但我的代理有效。
我已经按如下方式配置了代理,但连接错误仍然存在。
我的 ~/.bashrc
export HTTP_PROXY=http://127.0.0.1:8123/
export HTTPS_PROXY=http://127.0.0.1:8123/
export http_proxy=http://127.0.0.1:8123/
export https_proxy=http://127.0.0.1:8123/
$ cat ~/.npmrc
proxy=http://127.0.0.1:8123/
http-proxy=http://127.0.0.1:8123/
https-proxy=http://127.0.0.1:8123/
noproxy=localhost,127.0.0.1,192.168.,10.
strict-ssl=false
节点 v12.14.1 npm v6.13.7
我怎样才能减少错误?
谢谢你的帮助!
尝试使用此解决方案从代理后面安装电子节点模块。
npx cross-env ELECTRON_GET_USE_PROXY=true GLOBAL_AGENT_HTTPS_PROXY=http://username:password@host:8080 npm install -D electron@latest
username:password
是您的网络用户名和密码。host:8080
是您的代理服务器主机名和端口号。cross-env
是另一个支持命令行变量的节点模块(可选)。
