npm install -g @angular/cli 因语法错误而失败

Question

我有一个在 centos 7 容器上运行的 jenkins 作业。 一旦容器启动，jenkins 作业就会运行一个脚本 执行

 npm install -g @angular/cli

这已经工作了大约一年，但今天开始失败：

 /usr/bin/ng -> /usr/lib/node_modules/@angular/cli/bin/ng
 > @angular/cli@8.0.4 postinstall /usr/lib/node_modules/@angular/cli
 > node ./bin/postinstall/script.js

Answer 1

我能够解决这个错误。问题是当我安装npm 时，我只是执行了：yum -y install npm。我猜我必须使用的容器的 yum 存储库没有npm rpm 的最新副本。所以我改变了我安装npm的方式。现在我这样做：

yum install -y gcc-c++ make
curl -sL https://rpm.nodesource.com/setup_10.x | bash -
yum -y install nodejs
node -v
npm -v
npm install -g @angular/cli

根据https://tecadmin.net/install-latest-nodejs-and-npm-on-centos/

Answer 2

替换

npm install -g @angular/cli

在

npm install -g @angular/cli@~8.0.0

当前 8.0.4 版本 @angular/cli 存在依赖问题

使用 ~8.0.0 或更少（版本与 package.json 匹配的理想选择）

Answer 3

我刚刚在 Windows 上遇到了同样的错误：原来我有一个超级旧版本（v.6.11.0）的 Node，所以我会尝试在你的 centos 机器上更新本地版本的 Node（或者你的任何环境）在...上）。请注意，这也会更新您的 npm 版本（很可能）。
