Question

为了满足在Windows上安装IBM ApiConnect Developer Toolkit的必要条件，我尝试使用命令将npm升级到版本3 -

 npm install -g npm

以下是npm-debug.log的片段 -

Answer 1

首先，通过从提升的PowerShell运行以下命令，确保您可以在系统上执行脚本。要以管理员身份运行PowerShell，请单击“开始”，搜索PowerShell，右键单击PowerShell和select Run as Administrator。运行以下命令

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force

然后，要安装并使用此Windows升级程序工具，请运行（也可以从提升的PowerShell或cmd.exe运行）：

npm install --global --production npm-windows-upgrade
npm-windows-upgrade

最后通过键入

来验证普通cmd.exe或PowerShell中的npm版本

npm -v

Answer 2

chattopadhya，我遇到了同样的问题，我的解决方案是：

使用NPM 3安装NodeJS 6.14.0（LTS）
安装Windows Build Tools，版本3.1.0：npm install -g --production windows-build-tools@3.1.0
此任务将使您的NodeJS进入不安全状态：设置环境变量NODE_TLS_REJECT_UNAUTHORIZED=0以放弃TLS证书验证。（注意：对于在我自己的机器以外的计算机上执行此操作的任何后果，我不承担任何责任。）
最终安装的API Connect软件包，没有任何问题：npm install -g apiconnect。

希望有帮助。：）
