This is an oft-reported issue in the <a href="https://github.com/rust-lang/rls-vscode" rel="noreferrer">rls-vscode</a> repository, and I found the solution buried in some of the discussions (<a href="https://github.com/rust-lang/rls-vscode/issues/622#issuecomment-561596264" rel="noreferrer">1</a>, <a href="https://github.com/rust-lang/rls-vscode/issues/577#issuecomment-487231858" rel="noreferrer">2</a>).

The issue seems to be with the path to the <code>rustup</code> executable.
<code>rustup</code> works fine on the terminal, but VS Code cannot locate it.

Adding the following to the <code>setting.json</code> of the extension fixes the path for the extension.

<pre><code>"rust-client.rustupPath": "/home/XXX/.cargo/bin/rustup"
</code></pre>

@suj1th <a href="https://github.com/rust-lang/vscode-rust/issues/622#issuecomment-561596264" rel="nofollow noreferrer">first cited approach</a> fixed it for me. 
Add: <code>&quot;rust-client.rustupPath&quot;: &quot;$HOME/.cargo/bin/rustup&quot;</code> to your user settings.

My fix was to launch VSCode from the terminal with <code>code</code>.

On Windows:
<code>Start &gt; search for &quot;Edit environment variables for account&quot; &gt; Edit &quot;Path&quot; &gt; Add &quot;%USERPROFILE%\.cargo\bin&quot;</code>

blocks|key|99590|text|我在夜间使用时发现了这个错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|99591|把它放回稳定点，然后它就起作用了：|99592|cargo+default+stable|code-block|syntax|javascript|99593|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I got this error when using nightly. 
Set it back to stable, then it worked:
<pre><code>cargo default stable
</code></pre>

blocks|key|672541|text|我需要添加Windows+(没有$HOME)才能让它正常工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|672542|"rust-client.rustupPath":+"C:/Users/myusername/.cargo/bin/rustup"|code-block|syntax|javascript|672543|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I needed to add the Windows path (without $HOME) to get it to work.
<pre><code>&quot;rust-client.rustupPath&quot;: &quot;C:/Users/myusername/.cargo/bin/rustup&quot;
</code></pre>

After installing the <code>Rust</code> extension for VS Code, building the project fails with the following error:

<a href="https://i.stack.imgur.com/wLnmx.png" rel="noreferrer"><img src="https://i.stack.imgur.com/wLnmx.png" alt="Error Message Displayed by vscode"></a>

<blockquote>
 Couldn't start client Rust Language Server
</blockquote>



<blockquote>
 Rustup not available. Install from <a href="https://www.rustup.rs" rel="noreferrer">https://www.rustup.rs</a>
</blockquote>

This is in spite of the fact that <code>rustup</code> is installed in the system, and accessible from the VS Code terminal.

How do I solve "Couldn't start client Rust Language Server" with the Rust VS Code extension?
