如何安装旧版本的 Typescript？

Question

I recently installed Typescript 1.8 and found too many breaking issues. So for the time being I would like to install 1.7. Where can I get a link to down this?

Answer 1

要安装打字稿 1.7.5，请使用

npm install typescript@1.7.5

Answer 2

to install globally npm install -g typescript@1.7.5

to check open cmd and run tsc -v

to install it for the specific project you are working on change to the directory of your project

npm install typescript@1.7.5

and then check your package.json file

If you are using visual studio 2017, it may be using visual studio's version of typescript.

Answer 3

If you have a higher version of typescript and you want to install an Older version, you should Uninstall the current version by this command:

npm uninstall typescript

And then you can install the specific version you want like this for version(3.9.7):

npm install typescript@3.9.7

for Globally Install or Uninstall you can add -g to both of the above commands.
