Cannot install ‘libclang-dev‘--Ubuntu20.04 安装 libclang-dev 插件

Posted 2021-11-23 Z.Q.Feng

项目场景：

作者是在通过 dpkg 与 gdebi 安装 rstudio 的 deb 包时出现此错误的，本想着通过 apt 安装 libclang-dev 插件，但是绕来绕去都不成功。、

• 系统环境为 Ubuntu20.04 
• rstudio 版本为 1.4.1717 
• R 版本为 4.1.0

具体解决方法如下：

---

解决方案：

1. 安装 aptitude

打开终端，键入以下命令：

sudo apt-get install aptitude

2. 通过 aptitude 安装 libclang-dev

复制以下命令：

sudo aptitude install clang

接着我们可以看到如下输出：

/home/zq/Downloads> sudo aptitude install clang

The following packages have unmet dependencies:
 libc6-i386 : Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.3 is installed
The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     clang [Not Installed]                              
2)     clang-10 [Not Installed]                           
3)     lib32gcc-s1 [Not Installed]                        
4)     lib32stdc++6 [Not Installed]                       
5)     libc6-i386 [Not Installed]                         
6)     libclang-common-10-dev [Not Installed]             

Accept this solution? [Y/n/q/?] n
The following actions will resolve these dependencies:

     Remove the following packages:                                         
1)     libc-dev-bin [2.31-0ubuntu9.3 (now)]                                 

     Install the following packages:                                        
2)     libc-dev-bin:i386 [2.31-0ubuntu9.2 (focal-updates)]                  

     Downgrade the following packages:                                      
3)     libc6 [2.31-0ubuntu9.3 (now) -> 2.31-0ubuntu9.2 (focal-updates)]     
4)     libc6:i386 [2.31-0ubuntu9.3 (now) -> 2.31-0ubuntu9.2 (focal-updates)]
5)     libc6-dbg [2.31-0ubuntu9.3 (now) -> 2.31-0ubuntu9.2 (focal-updates)] 
6)     libc6-dev [2.31-0ubuntu9.3 (now) -> 2.31-0ubuntu9.2 (focal-updates)] 

注意这里第一个方案我们选 n 拒绝掉， 接着它会提示第二个安装方案，我们选取第二个安装方案：

Accept this solution? [Y/n/q/?] y
The following packages will be DOWNGRADED:
  libc6 libc6:i386 libc6-dbg libc6-dev 
The following NEW packages will be installed:
  binfmt-support{a} clang clang-10{a} lib32gcc-s1{a} lib32stdc++6{a} libc-dev-bin:i386{a} 
  libc6-i386{a} libclang-common-10-dev{a} libclang-cpp10{a} libobjc-9-dev{a} libobjc4{a}

Need to get 76.2 MB of archives. After unpacking 377 MB will be used.
Do you want to continue? [Y/n/?] y

接着一路点 y，我们就能成功安装 libclang-dev 了。
