Solusi Error: EACCES: permission denied, access '/usr/local/lib/node_modules'

Jadi ceritanya aku mau install package npm tapi kadang muncul pesan Error: EACCES: permission denied, access '/usr/local/lib/node_modules' .

Detail pesannya yang mucul di terminal seperti ini:

npm WARN deprecated [email protected]: request has been deprecated, see https://github.com/request/request/issues/3142

npm WARN deprecated [email protected]: this library is no longer supported

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

Nah ternyata setelah aku cari tahu ternyata aku ga bisa install karena semua di handle sama root, jadi kalo misal gagal seperti itu aku harus menambahkan perintah sudo misal: sudo npm install [nama-package]

karena aku menghindari perintah sudo, maka aku ganti handle accessnya ke user.

cara untuk nampilin user siapa aja yang bisa nge handle atau mengakses directory /usr/local/lib/node_modules:

    $  ls -la /usr/local/lib/node_modules

kalo di punyaku akan tampil seperti ini:

    ls -la /usr/local/lib/node_modules

    total 0

    drwxr-xr-x    8 root             wheel   256 May 26 01:35 .
    drwxrwxr-x  104 sanengineer      admin  3328 Aug 27 06:59 ..
    drwxr-xr-x    8 root             wheel   256 May 26 01:34 expo-cli
    drwxr-xr-x   11 root             wheel   352 Dec  4  2019 ghost-cli
    drwxr-xr-x   22 root             wheel   704 Mar  6  2020 gscan
    drwxr-xr-x   11 root             wheel   352 Dec  6  2019 gulp-cli
    drwxr-xr-x   13 root             wheel   416 May 23 03:14 nodemon
    drwxr-xr-x   23 root             wheel   736 Mar  6  2020 npm

Jadi dari hasil log terminal diatas, banyak permission directory yang hanya bisa di access oleh user root.

Oleh karena itu karena aku ingin mengganti permission directory .../node_module hanyak untuk nama User, jadi aku tulis perintah

    $ sudo chown -R sanengineer /usr/local/lib/node_modules

sanengineer adalah nama user di pc aku.

kalo misal di check lagi pake command dibawah ini:

    $ ls -la /usr/local/lib/node_modules

maka hasilnya seperti ini:

    $ ls -la /usr/local/lib/node_modules

    total 0

    drwxr-xr-x    9 sanengineer  wheel   288 Sep 20 06:47 .
    drwxrwxr-x  104 sanengineer  admin  3328 Aug 27 06:59 ..
    drwxr-xr-x    8 sanengineer  wheel   256 May 26 01:34 expo-cli
    drwxr-xr-x   11 sanengineer  wheel   352 Dec  4  2019 ghost-cli
    drwxr-xr-x   22 sanengineer  wheel   704 Mar  6  2020 gscan
    drwxr-xr-x   11 sanengineer  wheel   352 Dec  6  2019 gulp-cli
    drwxr-xr-x   13 sanengineer  wheel   416 May 23 03:14 nodemon
    drwxr-xr-x   23 sanengineer  wheel   736 Mar  6  2020 npm
    drwxr-xr-x   22 sanengineer  wheel   704 Sep 20 06:47 serverless

jadi kalo misal aku mau nge install sesuatu di directory node_modules aku ga perlu pake perintah sudo asalkan aku udah login di pc aku make user sanengineer.
