我无法构建旧的角度项目。我已经拉下代码,从npm install @angular/cli@1.7.4
开始,ng build抛出此错误:
@ angular / compiler-cli和打字稿的版本不能 决心。最常见的原因是npm安装失败。
请确保您的package.json同时包含@ angular / compiler-cli 然后在devDependencies中输入打字稿,然后删除node_modules和 package-lock.json(如果有),然后再次运行npm install。
我不确定1.7.4将是当前的cli版本,因为package.json不包含angular / cli。 如何在不触摸代码的情况下还原此项目的所有内容?
更新:
我已经将@ angular / compiler-cli @ 2.4.5和typescript@2.3.4安装到devDependencies中。这篇文章也包含更新的package.json。该错误现在显示:
在
.angular-cli.json
中找不到任何应用。
那是因为我没有.angular-cli.json。不需要此文件的angular cli的最新版本是哪个?
更新2:
我创建了一个.angular-cli.json文件并尝试构建该项目。在进行一些jsonn文件修改时,我遇到了一个错误的错误:
TypeError:无法读取未定义的属性“ length”
我想这是来自较旧的cli / compiler / typescript版本,但是如何确定真正的问题呢?
如果我开始更新cli和其他更新,那将是一场灾难,因为我无法停止将Angular更新到7.2,这意味着很多代码更改。 (尝试过这一天,一天后就放弃了。)

在阅读了GitHub存储库上报告的一些问题之后,我找到了解决方案。
为了更新系统中全局安装的angular-cli软件包,您需要运行:
npm卸载-g angular-cli npm缓存清理或npm缓存验证(如果npm> 5) npm install -g @ angular / cli @ latest 根据您的系统,您可能需要在上述命令前加上sudo前缀。
此外,您很可能还希望更新本地项目版本,因为在项目目录中将其选择为比全局目录更高的优先级:
rm -rf node_modules npm卸载--save-dev angular-cli npm install --save-dev @ angular / cli @ latest npm install
