title: error TS5014: Failed to parse file 'tsconfig.json': Unexpected token / in JSON at position 57
body: <p>I moved my typescript project to a win 7 computer.
  I get this error when the tsconfig works perfectly fine in my win 10 computer.
  I removed the last two trailing commas as suggested <a href="https://github.com/nrwl/nx/issues/1462" rel="nofollow noreferrer">here</a> and the error persists.</p>
  <p>My tsconfig:</p>
  <pre><code>{
    &quot;compileOnSave&quot;: true,
    &quot;compilerOptions&quot;: {
      /* Visit https://aka.ms/tsconfig.json to read more about this file */
      /* Basic Options */
      // &quot;incremental&quot;: true,                   /* Enable incremental compilation */
      &quot;target&quot;: &quot;es5&quot;,                          /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', 'ES2018', 'ES2019', 'ES2020', or 'ESNEXT'. */
      &quot;module&quot;: &quot;commonjs&quot;,                     /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', 'es2020', or 'ESNext'. */
      &quot;strict&quot;: true,                           /* Enable all strict type-checking options. */
      // &quot;esModuleInterop&quot;: true,                  /* Enables emit interoperability between CommonJS and ES Modules via creation of namespace objects for all imports. Implies 'allowSyntheticDefaultImports'. */
      //&quot;inlineSourceMap&quot;: true,                  /* Emit a single file with source maps instead of having a separate file. */
      //&quot;inlineSources&quot;: true,                    /* Emit the source alongside the sourcemaps within a single file; requires '--inlineSourceMap' or '--sourceMap' to be set. */
      &quot;sourceMap&quot;: true,
      /* Advanced Options */
      &quot;skipLibCheck&quot;: true,                     /* Skip type checking of declaration files. */
      &quot;forceConsistentCasingInFileNames&quot;: true, /* Disallow inconsistently-cased references to the same file. */
      &quot;outDir&quot;: &quot;./src/ts-built&quot;,
      //&quot;rootDir&quot;: &quot;./src&quot;,
      // &quot;strictNullChecks&quot;: false,
      &quot;baseUrl&quot;: &quot;src&quot;,
      &quot;allowJs&quot;: true,
      &quot;downlevelIteration&quot;: true
    }
  }
  </code></pre>
  <p>It also surprises me that when I run</p>
  <pre><code>tsc --init
  </code></pre>
  <p>I obtain:</p>
  <blockquote>
  <p>error TS5023: Unknown compiler option 'init'.</p>
  </blockquote>
  <p>Thanks for any help.</p>
