TSConfig 未知编译器选项“lib”

Question

I am taking over an old angular 1 project with typescript 1.8.10.

However I can't compile and it keeps throwing me this :

Unknown compiler option 'lib'

if i comment out the "lib" line, then I will face a huge load of other errors such as

 Property 'X' does not exist on type 'Y'

this is a fairly huge old project and I only want it to run for 2 weeks, so re-coding it is not an option for me due to timeline.

I have tried changing many versions of typescript, but the same issue shows for me, I also tried to build using --noImplicitUseStrict but it doesn't help.

Here is my tsconfig.json and my package.json

tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
      "module": "commonjs",
      "target": "es5",
      "noImplicitUseStrict" : true,
      "lib": ["es2015", "dom"]
 },
  "exclude": [
      "bower_components",
      "node_modules",
      "typings"
  ]

Please give me some advice on this. I am building it using Gulp.

Answer 1

In my case, I just forgot to npm install before npm build . It might help someone.

Answer 2

lib is a TypeScript 2 feature, and as you mentioned you are using 1.8. You could remove that lib from the tsconfig.json or Try upgrading to a newer typescript version.

In my package.json, I'm using the following dev dependencies:

"ts-loader": "^5.4.4",
"typescript": "^3.4.5",

However, you may find some of your typescript breaks if you upgrade.
