在curl的页面上有关于SSL和证书问题的很好的信息。 我的大部分答案都是基于那里的信息。

使用strict-ssl false是不好的做法，可能会产生问题。我们可以做的是添加由“中间人”证书注入的证书。

如何在Windows上解决这个问题:

Download the CA Certificates from curl based on Mozilla's CA bundle. You can also use curl's "firefox-db2pem.sh" shellscript to convert your local Firefox database. Go to a webpage using https, for example Stackoverflow in Chrome or Internet Explorer Click the lock icon, click View certificates or "Valid" in Chrome Navigate to the Certification path. The top certificate, or the root certificate is the one we want to extract. Click that certificate and then "view certificate" Click the second tab, "Details". Click "Copy to file". Pick the DER format and make note of where you save the file. Pick a suitable filename, like rootcert.cer If you have Git installed you will have openssl.exe. Otherwise, install git for windows at this stage. Most likely the openssl executable will be at C:\Program Files\git\usr\bin\openssl.exe. We will use openssl to convert the file to the PEM format we need for NPM to understand it. Convert the file you saved in step 5 by using this command: openssl x509 -inform DES -in **rootcert**.cer -out outcert.pem -text where rootcert is the filename of the certificate you saved in step 5. Open the outcert.pem in a text-editor smart enough to understand line-endings, so not notepad. Find -----BEGIN CERTIFICATE----- lots of characters -----END CERTIFICATE----- and copy all text between them and also including the BEGIN / END lines Now we will paste that content to the end of the CA Cert bundle made in step 1. So open the cacert.pem in your advanced texteditor. Go to the end of the file and paste the content from previous step to the end of file. (Preserve the empty line below what you just pasted) Copy the saved cabundle.pem to a suitable place. Eg your %userprofile% or ~. Make note of the location of the file. Now we will tell npm/yarn to use the new bundle. In a commandline, write npm config set cafile **C:\Users\username\cacert.pem** where C:\Users\username\cacert.pem is the path from step 10. Optionally: turn on strict-ssl again, npm config set strict-ssl true

唷!我们成功了!现在npm可以理解如何连接了。额外的好处是，您可以告诉curl使用相同的cabundle。pem，它也能理解HTTPs。

在cmd或GIT Bash或其他提示符下使用以下命令

$ NPM配置代理http://192.168.1.101:4128

$ NPM配置http -proxy http://192.168.1.101:4128

其中192.168.1.101为代理IP, 4128为端口。根据您的代理设置进行更改。这对我很有用。

Windows系统

尝试删除代理和注册表设置(如果已经设置)，并通过命令行设置环境变量

SET HTTP_PROXY=http://username:password@domain:port
SET HTTPS_PROXY=http://username:password@domain:port

然后尝试运行NPM install。这样，你就不用在.npmrc中设置代理了，但是对于那个会话，它是可以工作的。

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

在最后捆绑了不同的答案后，@Kayvar回答的前四行帮助我解决了这个问题:

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

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
