Angular 2问题:typings:找不到命令

Question

所以这可能是一个非常基本的问题,但它已经困扰我好几天了,实际上还没有找到解决方案.

我正在使用npm从命令行安装打字输出,它似乎运行良好但我输入任何打字命令,它说该命令不存在!

它类似于:

    Kevyns-MacBook-Pro:~ kevynquiros$ sudo npm install typings --global
Password:
/Users/kevynquiros/npm/bin/typings -> /Users/kevynquiros/npm/lib/node_modules/typings/dist/bin.js
typings@1.0.4 /Users/kevynquiros/npm/lib/node_modules/typings
??? listify@1.0.0
??? xtend@4.0.1
??? wordwrap@1.0.0

??? minimist@1.2.0

??? typings-core@1.0.1 (array-uniq@1.0.2, thenify@3.2.0, zip-object@0.1.0, popsicle-status@2.0.0, graceful-fs@4.1.4, popsicle-retry@3.1.0, throat@2.0.2, lockfile@1.0.1, promise-finally@2.2.0, string-template@1.0.0, strip-bom@2.0.0, sort-keys@1.1.2, make-error-cause@1.1.0, debug@2.2.0, has@1.0.1, rc@1.1.6, object.pick@1.1.2, configstore@2.0.0, parse-json@2.2.0, invariant@2.2.1, detect-indent@4.0.0, mkdirp@0.5.1, touch@1.0.0, is-absolute@0.2.5, popsicle-proxy-agent@2.0.1, rimraf@2.5.2, typescript@1.8.7, popsicle@6.2.0)

然后就是这样:

Kevyns-MacBook-Pro:~ kevynquiros$ typings search tape
-bash: typings: command not found

请帮忙!

Answer 1

尝试使用 npm install typings -g

Answer 2

从您的问题中的cmd输出开始,typings安装包/Users/kevynquiros/npm/bin/typings.您需要将该文件夹添加到您的PATH.

一种方法是:

• 创建"或编辑"文件 /Users/kevynquiros/.bash_profile

• 在该文件中,添加一行:

  export PATH=${PATH}:/Users/kevynquiros/npm/bin/

• 关闭并重新打开terminal,它应该工作.
