当我在代理设置中没有http/http前缀时，即使代理主机和端口是正确的值，npm也会失败。只有在添加协议前缀后，它才能正常工作。

去环境变量和删除或设置为空

HTTP_PROXY和HTTPS_PROXY

这也将解决企业环境的代理问题

如果有疑问，试试所有这些命令，就像我做的那样:

npm config set registry http://registry.npmjs.org/
npm config set proxy http://myusername:mypassword@proxy.us.somecompany:8080
npm config set https-proxy http://myusername:mypassword@proxy.us.somecompany:8080
npm config set strict-ssl false
set HTTPS_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
set HTTP_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
export HTTPS_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
export HTTP_PROXY=http://myusername:mypassword@proxy.us.somecompany:8080
export http_proxy=http://myusername:mypassword@proxy.us.somecompany:8080

npm --proxy http://myusername:mypassword@proxy.us.somecompany:8080 \
--without-ssl --insecure -g install

更新

将您的设置放入~/。Bashrc或~/。Bash_profile，这样你就不必担心你的设置每次打开一个新的终端窗口!

如果你的公司像我的公司一样，我必须经常更改密码。因此，我在~/中添加了以下内容。Bashrc或~/。这样每当我打开一个终端，我就知道我的npm是最新的!

Simply paste the following code at the bottom of your ~/.bashrc file: ###################### # User Variables (Edit These!) ###################### username="myusername" password="mypassword" proxy="mycompany:8080" ###################### # Environement Variables # (npm does use these variables, and they are vital to lots of applications) ###################### export HTTPS_PROXY="http://$username:$password@$proxy" export HTTP_PROXY="http://$username:$password@$proxy" export http_proxy="http://$username:$password@$proxy" export https_proxy="http://$username:$password@$proxy" export all_proxy="http://$username:$password@$proxy" export ftp_proxy="http://$username:$password@$proxy" export dns_proxy="http://$username:$password@$proxy" export rsync_proxy="http://$username:$password@$proxy" export no_proxy="127.0.0.10/8, localhost, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16" ###################### # npm Settings ###################### npm config set registry http://registry.npmjs.org/ npm config set proxy "http://$username:$password@$proxy" npm config set https-proxy "http://$username:$password@$proxy" npm config set strict-ssl false echo "registry=http://registry.npmjs.org/" > ~/.npmrc echo "proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "strict-ssl=false" >> ~/.npmrc echo "http-proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "http_proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "https_proxy=http://$username:$password@$proxy" >> ~/.npmrc echo "https-proxy=http://$username:$password@$proxy" >> ~/.npmrc ###################### # WGET SETTINGS # (Bonus Settings! Not required for npm to work, but needed for lots of other programs) ###################### echo "https_proxy = http://$username:$password@$proxy/" > ~/.wgetrc echo "http_proxy = http://$username:$password@$proxy/" >> ~/.wgetrc echo "ftp_proxy = http://$username:$password@$proxy/" >> ~/.wgetrc echo "use_proxy = on" >> ~/.wgetrc ###################### # CURL SETTINGS # (Bonus Settings! Not required for npm to work, but needed for lots of other programs) ###################### echo "proxy=http://$username:$password@$proxy" > ~/.curlrc Then edit the "username", "password", and "proxy" fields in the code you pasted. Open a new terminal Check your settings by running npm config list and cat ~/.npmrc Try to install your module using npm install __, or npm --without-ssl --insecure install __, or override your proxy settings by using npm --without-ssl --insecure --proxy http://username:password@proxy:8080 install __. If you want the module to be available globally, add option -g

我是这样解决这个问题的:

我运行这个命令: NPM配置strict-ssl为false 然后设置npm运行http，而不是https: NPM配置注册表http://registry.npmjs.org/ 然后我使用下面的语法安装包: NPM——proxy http://username:password@cacheaddress.com.br:80安装packagename

如果代理不要求您进行身份验证，则跳过用户名:密码部分

编辑:我的一个朋友刚刚指出，你可以通过设置HTTP_PROXY和HTTPS_PROXY环境变量来让NPM在代理后工作，然后正常地发出命令NPM install express(例如)

EDIT2:正如@ bstruthers评论的那样，请记住，包含“@”的密码不会被正确解析，如果包含@，则将整个密码放在引号中

在我的情况下，我忘记在配置文件中设置“http://”(可以在C: \Users \ [USERNAME] \ .npmrc中找到)代理地址。所以我们不需要

proxy=http://[IPADDRESS]:[PORTNUMBER]
https-proxy=http://[IPADDRESS]:[PORTNUMBER]

我有

proxy=[IPADDRESS]:[PORTNUMBER]
https-proxy=[IPADDRESS]:[PORTNUMBER]

这当然没有工作，但错误消息也没有多大帮助…

要设置http代理，请设置-g标志:

Sudo NPM配置代理http://proxy_host:port -g

对于https代理，再次确保设置了-g标志:

Sudo NPM配置http -proxy http://proxy_host:port -g
